Needed: a trick to debug a circuit on a breadboard - (The Spaghetti Incident)

The situation: I'm prototyping a circuit with a 14-legged logic IC on a breadboard. What happens: The picture tells it all: The breadboard looks like a Spaghetti Incident. What a mess. It's hard to find the right holes between all the leads sticking out, and avoiding shorts is even trickier. And of course: The circuit doesn't work. Not suprising considering the chaos. No biggie, but debugging a circuit on such a breadboard is a real pain! So please: Share your tips / tricks / magic to keep a proper and readable circuit on a breadboard. Thanks! Ynze PS: The circuit is not very complex btw. It's a solar engine, with one logic IC (NAND gates) and about 15 other parts. The circuit does contain feedback loops, which make it a bit trickier...

Looking for Eagle file for standard breadboard power.

Hello;   I am trying to find an Cadsoft Eagle .brd file. I want to plug boards into a standard breadboard, for power. I want to plug onto the thin side. It seems to be a metric measurement, even though it is 0.1" hole spacing. Or if someone has the spacing info for the pins? I measured 4mm on centre, then 40mm to 51mm for the far row. So it would be on the left or right of the breadboard. I always round ground at the outside, and 5v in the middle. So swapping ends will work. Thanks, and I will keep looking Mick M

I will paypal someone $10.00 dollars to draw this in breadboard fashion for me!

Hi, I really need help. I've been working on this dern motion detection alarm and am having problems with the delay circuit. I think I have assembled it right and it never works. I have completely re-done it twice! What it is supposed to do is once power from the relay is sent to the 555 timer it will impose a 1 minute delay before sending the power to the alarm/horn. This gives owner adequate time to enter code to disarm. The relay part of the circuit works fine and sends power to the 555 timer and latches as it should. However, the 555 timer never sends power out of pin 3. Could someone please, please, please draw the attached schematic in breadboard fashion so I can double check everything is assembled properly? I would really appreciate it!!! Anyways I will paypal someone $10.00 dollars to draw this in a breadboard layout for me!

Circuit works when I poke a connection, but the connection is sound

So, I've started playing with vfds since this weekend jaycar (if your an Aussie) is selling 11 digit, 10 segment vfds for $1.90. Cheap as :P. It runs off 12v for the segments, 4.5v for the filament. I'm using 3 4094s to control the segments and an atmega168 to control the 4094s, using 3 transistors to up the voltage between the 4094s data, clock and latch pins and the the atmega I/O ports. I'm pretty sure everythings hooked up correctly but, as with most projects, it's not working first time :P. Here's the thing, it works if I poke either the green or brown connection with just one probe of my multimeter/finger it works. My first thought is that i've hooked up my transistors incorrectly, the base is 5v with a 2.2k current limiting resistor, and the collector is 12v with a 5.1k current limiting resistor. To much? I blew out a resistor in initial testing and it got me a little worried :P Thoughts?

Odd Breadboard Question

Hi All  I am brand new to hobby electronics and would love one day to be able to create the endless amount of cool Instructables but I have ran into a problem on my first attempt at putting theory into practice and would really appreciate any help. I have made two diagrams / images showing the circuit I made I have attached them to this post. I am using an Arduino Uno as a power source.... I ran a 5v positive from the 5v pin on the Arduino using solid core jumper to the top of the breadboard onto the positive row / rail and a negative / ground jumper to the bottom of the breadboard. In the middle of the breadboard I placed a 1k ohms resistor bridging the gap / grove/ divide and ran the positive feed through it and on to the anode leg of the LED. The cathode leg of the LED was connected to the negative row / rail completing the circuit. All works as it should because of the high resistance from the resistor the LED barely lights and is green as it should be. So without using a multimeter I know and can see the resistor is clearly working. However if I move the resistor so it's still on the same line / row as it was but no longer bridging the gap the LED goes super bright and turns yellow which means that the resistor is no longer working which I can't figure out why because I know there is definitely current flowing through it given the extreme reaction of the LED. I vaguely remember reading somewhere on these forums that Fritzing is not liked very much so I hope no one minds but to help explain what I mean above I have created two diagrams / pictures using Fritzing. The images diagrams shows the resistor "bridging" and working and the other shows it not bridging and therefore not working. So my question would be why given the resistor has current flowing through it does it not work unless it's bridging this middle divide / gap / grove? It makes me think I am missing something really stupid that everyone should know about breadboards but just seems really odd to me. Many Thanks Rab

FREE Schematic publisher(also includeds breadboard and PCB view)IN ALPHA

I did a search and didn't see it on this site anywhere, but I see a huge need for a number of the members here to be able to draw schematics and even simulate a breadboard or PCB. This software is free(but it is still in ALPHA testing). I have no affiliation with this site so I can only answer questions about usability from my opinion. For what a lot of people need on this site to help make "instructables"  that have electronic curcuits in them I think this is perfect. Especially if you can't afford high dollar software, plus if you're not an electronic engineer this software will teach you proper terminalogy and proper drawing designations as well. From what I know, all parts on the program are editable. So if you need a green 3.6v LED you can edit the one that comes default on the program and save it in your tool kit and use it for another project later. Hopefully everybody sees this. If the Mods know of a place to put this where it may be more accesible and visible to everybody here, please move it. Here's the link to find the software. They have it for Windows, Mac OSX, Linux 64 and 32 bit Enjoy PS, don't forget this software is in Alpha, so contact the devs and tell them if you have problems or you'd like to see changes

Quick question

Hi, I need help. You see the street I live in has more cats than, well the musical cats,  and seeing as my garden seems to be they're preferred  choice for going to the toilet, I decided to build a motion sensing water sprayer. So off to Amazon I went and purchased some PIR sensors, a solar pump with a DC connection, bread boards wires and batteries and chucked it all together. Now the sensor will light an LED no problem but when I switch in the pump I get nothing. I read on tinternet that transistors can be used to up the juice but I was already far beyond my knowledge of circuits, components and the like. I even tried looking at sketches of PIR sensors to transistors, but after weeks of trying I'm no closer and have nothing to show for it but a headache.  If anyone can help and describe to me (in child like, basic terminology) how I wire up a transistor to a PIR and then a 4-12v 3.5watt pump that would be just super.  Or at-least put me out of my misery and tell me it's not doable.  Thanks.

Looking for advice on panel mount connectors (something like banana plugs)

Not sure if Tech is the right place to post but it seems appropriate. I have been doing some breadboarding lately and in an effort to clean up my work I plan on making a box/panel with several commonly used components (potentiometers, audio jacks, DC jacks, other sockets). I would like to have some sort of quick way of connecting these components to a breadboard. I saw a post here in instructables on how to make Banana plug to breadboard pin jumpers. The only problem I have with this solution is that all of the panel mount banana plug jacks I can find are fairly pricey and somewhat bulky for what I want. Does anyone know of something like a panel mount breadboard socket? The components I will be using will have anywhere from 2-9+ wires coming from them so I would like a way to have some sort of socket or connector mounted with the component and use wires to connect to the breadboard only when the component will be used (as to avoid lots of excess, unused wires coming from my panel). A source of cheap banana plug jacks (female, panel mount) and crimp on male plugs would help as well, if I cant find another option.

Schematics, Help Please

Hello, I'm trying to create a simple timer that sets off a device after a set amount of time. I'm using a schematic from a basic electronics book that my grandfather had given me a few years ago. And it seems simple enough to the point where I can understand how it works. But I just can't seem to figure out how to actually put it down on a breadboard to even test it. So if you could possibly help me find out how to place this down on a breadboard to at least test, I thank you very very much. -The picture of the schematic should be below.

Robot troubles.

I am trying to build a mini-sumo edgebot, as featured in Junkbots, Bugbots and Bots on Wheels. Below is a quick scan of the schematic I'm following. It is supposed to drive forwards until the edge sensor closes, at which point it will reverse and turn before carrying on.Trouble is, it doesn't work.The symptoms:I have breadboarded the circuit, and when I connect the battery, it runs. But when I make the connection to simulate the edge sensor, both motors kick into reverse, but only for a fraction of a second, and then never again - further touches of the edge sensor elicit no reaction at all.When I disconnect the battery, and trip the sensor, the LEDs light and the relays click, showing that the capacitor is still charged.The only things in the breadboard not to "spec" are the motors - I haven't bought my intended motors yet, so I am trialling with a pair of un-geared 3V motors (these are the motors I intend to buy: item number 5855781458 )How can I fix it so that it will react to the edge more than once in a combat?

Hi,I breadboarded the pin-pointer metal detector and am having trouble with the front end. pcounterA reads 11-14 on the serial port monitor.See previous question on instructibles reproduced below:_________________Asked by jont4e 2 days ago Hi, I bread-boarded your circuit for just the end coils to start, and loaded the sketch. It seems to be pulsing the coil OK but the leds aren't responding nor the buzzer. I uncommented the serial port code and it shows ledthreshold1 always at .97, pcounterA at 12, and calav1 at 81. Is this OK? (The other reported variables are always 1000.) I wound the end coils with some bifilar wire I reclaimed from a microwave HV supply transformer. I assumed that was OK? Do you have a flow chart or description of how the code works so I can troubleshoot? Any help or hints would be greatly appreciated. Jon T 0 Answer from TechKiwi... 2 days ago The pcounterA value should be much higher 200 to 800 at least. My advice is to focus on one channel. Try reversing the polarity of one of the coils as this often is the problem as the pulseIn function needs to have a clean leading edge to trigger the timing process. Ensure your breadboard connections to the coil are short and well grounded. If this does not work direct message me with a link to some photos of your setup and I will try to assist. I'm just building a second unit so your timing is fortuitous as I can provide some test measurements._______________________________Attached are images of the front end scope traces and a shot of the breadboard. Coils are off screen to the left.Swapping coil polarity did not seem to change any waveforms.Hope someone has some suggestions I can try.JT

help with a chaser board

Hi all i am very very new to all of this and i am working to light up a model if you can help me i would be very great full. Ok so i want to connect Led 1 threw 5 to the 555 timer and 6and 7 to be solid on. The resistors are 1/4 W 5% 470R OHM I was told to put the resistors on the negative point of the LED for the chasers. Do i need to put some on the Solid ones? I am using 4 AA Batteries for power and that gives me 6V. All of the lights will be in a serial circuit. The chasers Led are 3mm 5.0V @ 20mA The solid Led are 3mm 3.6V @ 20MA The fun part: How do i connect it all together? I bought a Breadboard and i am trying to figure it out lol !!! Now i was told that the timer chip is to bridge the gap image 2 That i also has to connect the the bottom and top of the gap like so image 3 OK so on the breadboard the resistors go parallel? from the 555 chip image 4? And the Led goes like this for the chaser image 5 ? Any help would be great and thanks

making webcam/monitor

Hello i am hoping that i can build a simple webcam or monitor with a cellphone that i've stripped down. i have the image sensor... i am just a beginner at electronics so i dont know much about it. i hope its possible to make one (i really really wanted to make one no matter what it takes) i have some other tools like the essential breadboard, capacitors, resistors, and some other stuffs thanks!

FT232RL+breadboard arduino programming problems

I am trying to program a breadboard arduino with an ft232rl programming adaptor that I found online. I made the 'duino using a atmega 328 preloaded with arduino uno optiboot from sparkfun. I attached 5volts power, 16mhz crystal, reset button, and an led to pin 13. When power is supplied, the led pulses then stopps suggesting that the bootloader is working correctly. I then connected a ft232rl to the arduino with rx to tx and tx to rx as well as the DTS pin to a 0.1 UF cap and to reset. Then i connected it to my computer via usb and installed the VCP drivers. It shows up as a com port in the IDE and I selected the board as an uno and tried to flash the blink sketch. The lights on the breakout blink, but i keep getting the avrdude not in sync message. I have tried switching cables, usb ports, pressing the reset button while programming, i have gotten rig of the 0.1 uf cap and jumped directly to DTS, i have tried both sets of drivers and have restarted the board, my computer, and the IDE as well as feeding a separate 5 volt source to the chip. How can I fix this? I am using windows vista SP1 with ide version 1.0.1 and a cheap programmer from ebay.

My iPod Crystal Radio Idea

I'm Sure someone has had this idea before but I just want to know if people think this would be cool. I was thinking about make a breadboard with a crystal radio transmitter with a head phone jack sticking out of it, that would fit in some sort of case, and have it stick into my iPod Nano 3rd Generation. My iPod is red so I would paint the case red to match, Please post idea and links to the parts please.
