Pet Feeder

There is a feral cat that I have been feeding, but I am afraid it now depends on me for food. If I go on a vacation I want to be able to feed it dry kibbles, but there are raccoons and other critters that would eat food left out. I have looked at several DIY feeders but they are too complex for my taste. What I would like is something that, when it got a power input from a 24 hour timer, would send power down to some sort of solenoid that I could use to open a box of food. But I would need a series of these in sequence so that the next time the timer sent power it would complete a circuit to the next solenoid the next day and then do it again for up to seven times (so I could be gone for seven days). What sort of device would sequence power to different solenoids to open a series of boxes? Thanks in advance.

How to make: LED circuit that can be switched on and off sequentially using an input button

Dear Instructables Community, I am trying to create the following LED circuit for a school project and would be grateful for any help. I would like to create a circuit containing a grid (see attached image) with 2 rows of LEDs in 3 columns. In this circuit, pressing an input button must move the "LIGHT ON" signal from 1 LED to the very next LED on the circuit in the following manner: Button click -> RowA column1 "ON" (Rest OFF)- > button click -> RowA column2 "ON" (Rest OFF) -> button click -> RowA column3 "ON" (Rest OFF)-> button click -> rowB column1 "ON" (Rest OFF) -> etc etc eventually leading to RowB Column3 "ON" (Rest OFF) -> button click -> rowA column1 "ON" (Rest OFF) -> etc etc 1) What would be the simplest circuit design for such a circuit? 2) How difficult would it be to add a second input that moves the "light on" down a column? (The circuit would then have 2 inputs: 1 button to move "light on" down a row, and the other input to move "light on" down a column. Looking forward to your advice! Thank you :-)

How to make a 2-row Sequential LED flashing circuit? Answered

I want to make a circuit that lights up two LED's then turn them off then lights up the next two LED's and so on. I want it so it looks like the light is scrolling across the LED's. I know how to do this with one row but how do I do it with two rows so that the two row are in sync? *Update: August 8, 2013* I have a ramp for my R/C car with 2 rows of 6 LED's. I want the bottom two to light up, then turn off. Then the next two above them to light up, then turn off and so on. As if the light was travel from the first two LED's, to the second one, to the third, to the fourth and so on. Then have the light come back to the start. I'm also really new to electronics so, if possible, try to keep it as simple as possible.

How to make 6 led blink in a repeatedly sequence ? Answered

Hello everyone, I am a novice in all  of this and  I really need help.

How to connect 10 lights or LED's in sequence having all lights on when the switch reaches 10?

I want to construct a panel with a 10-position rotary switch that lights a vertical column of lights or LED's.  At position 1 the bottom light is on, at position 2 both lights 1 and 2 are on. At position 8, lights 1 through 8 are all on until at position 10 all 10 light are on.  The bottom lights will be green... then middle lights yellow, and finally red lights at the top.  I was going to use LED's but for 10 it seems I may need 24v supply?  If I use 6-volt lamps, maybe I can get then to stay on with a 6-volt lantern battery or 9v battery ?  Can I simply use a rotary switch and blocking diodes to keep the next light from coming on too soon?  This is such a simple idea but I have not found a simple solution yet - any help will be very much appreciated.

Building a flasher circuit with a single led to flash Once, then Twice, then Three times, and then loop it? Answered

I've built some simple flasher circuits in high school, but what I need now requires a bit more than a simple flasher. I want to avoid using a micro controller or arduino. I hope there is a simple way to just loop a simple flasher circuit through multiple stages of capacitors or something, but that's why I've come here. :) This is what I need: A flasher circuit with a single LED, flashing in 3 sets before looping. It will flash ONCE (Beep). And then TWICE in quick succession (BeepBeep). And then THREE times in quick succession (BeepBeepBeep). There needs to be a delay between each set of flashes. After the 3 sets of flashes, it will loop and do it again and again. I would love lots of help on this! Thanks so much.

Update - Circuit problem: Can anyone figure out what may be causing this project to only work half way?

Ok, I have a recently built prototype of a circuit I was going to publish, but it is not working exactly as planned. It is not that it is not working at all, but it is acting strangely.What is happening: pairs are blinking alternately, when they should be blinking in sequence. Can anyone see a fundimental flaw in my drawing, or is it a possible soldering error. Opinions and insights welcome. PS: the included video is the first one I have even edited too (I forgot that the camera picked up sounds, and I had grunted, and verbally expressed surprise and it sounded inappropriate, so I edited it out.)PPS: I believe I have to declare FAILure on this one, at least for now.

LED Decade Counter IC?

Help me light some LEDs with an IC. Is there a simple 10-stage counter IC, just like the 4017, but where the outputs stay high until the chip resets. So the output would be as following: 1000000000 1100000000 1110000000 1111000000 1111100000 1111110000 1111111000 1111111100 1111111110 1111111111 and then repeat I'm building a circuit where the number of lit LEDs constantly increase. Do you know of a chip that can do this? Or can it only be achieved with a PIC? Thanks in advance Martin

How do I make a string of LEDs light up in sequence (one after another as if the the light is "moving")? Answered

I am trying to make it so when I press a button the LEDs would "run" up and down the strand a few times and then all blink at once (totaling about 5-10 seconds).

12v water pumps on/off running in sequence? Answered

Hello everyone. I am trying to create a demonstration of my waterproofing products. As it stands i have a single water pump inside a 25x25x25 clear acrylic cube. At the moment they are either on of off. I have 3 of these in total. See attached image. What i am trying to achieve is the pump to come on for an amount of time (roughly 2 seconds) then off for an amount of time (roughly 2 seconds) then repeat the cycle on loop. What I would like is to have the ability to change how quickly or slowly the cycle loops (longer ON duration etc) and also which pump activates first and in which order.  The pumps are UK plugs adjustable from 3v - 12v which changes the litres p/hr  I've done some research but not sure if arduino will do the job? I'm complete novice so your help and advice would be greatly appreciated. As much detail of the items required and where to source in the UK would be amazing.

HELP! Electronic sequencer for vintage door chime.

Seeking any manner of help in making an electronic sequencer for a multi-note doorbell. I restore old door chimes and one particular model from the 1940's-1950's has an electromechanical linear distributor that works as the chime sequencer. It has a limited life expectancy- long since expired- and it defies repair. You can see details of this device by looking up patent number 2245443. The task to be done though is just like that of any more common chime sequencer that uses a rotary distributor. The idea is to replace the electromechanical mess with modern electronics to time the power sequence to three or four 16v or 24v solenoids. Looking for any help… guidance, advice, moral support... but mostly hoping to find someone who can design and build a few of these, as I am largely clueless about electronic design.

How to make a "Timed" LED Color Sequencer ?

I would like a "timed" LED Color Sequencer. So instead of a board that flips between leds or strobes I want it to stay in a color for a couple of minutes. Ex: green for 3mins, then fade to red for 3mins, then fade to blue for 3mins then fade back to green.. Time as 3mins is just a example but must be for a longer period then just a fade and longer then just a couple of sec. It must be driven with small batteries, must be driven on its own so no interference of people as a touchpad to switch/fade.How would one do such a idea, do I need to have a microproc or can I skip that ?

starting circuit for programmable sequence, for flashing LED?

Hi- I am interested in suggestions for starting points to build a programable flashing LED.  The intervals of dark/light should be configurable, kind of like morse code.  But not subject to what I recall as requirements for Morse- dashes are 2x as long as dots, or something- duration will vary for both.  Maximum total length of sequence is 10 seconds. There are a lot of flashing LED circuit Instructables, some very old and referencing 7 yr old chips- unsure if I can get those chips. In an ideal world, when I am done, I could have multiple EEPROMs that I could switch out to configure the flash sequence I wish.  One sequence per EEPROM.  Or another means to accomplish this. My background:  I can solder a little, I can program and shell script a little, I have not much idea about electronics at all. Thank you for pointers to a jumping-off spot for me!

How can I sequence several small motors. Answered

Wife approved Home Theater ​I plan to build raised panel cabinets that also hide home theater speakers and 60" screen. Open display/bookshelves sit between the speaker garage and the 60" screen. The raised panel (I'll make with my 5hp shaper) covering the speaker will roll over the display cabinet allowing the speakers to move out into the room on motorized platforms. Then, the speakers will rotate on a motorized turntable  to the desired position. Next, the two panels covering the screen will move under the speaker panels and also cover the display cabinet plus a little of the garage space. I want this to all be initiated with the push of a button. The motors will all be sequential in the above order. First, the speaker panel can roll until it hits a button, next, the speaker platform movement could be controlled by motor revolutions as in a stepmotor and would stop the platform at the right spot. When this action is complete, the speaker rotation could also use a step motor count. Next, the two screen panels will roll under the speaker panels until they hit a final stop button. I will need a central controller to manage the sequence order. I am familiar with Fishertechnik robotics controllers but I'm hoping that someone here can give me some suggestions to make this work. Thanks for reading. Chuck

Simplest way to make an LED flash (part of) the Fibonacci Sequence? Answered

I'm trying to figure out if I can make one (or possibly several) LEDs blink maybe the first 15 Fibonacci numbers. Wonderfully awesome (but unnecessary) would be if I could also have it emit a sound (loaded from my computer) at the same time, in sync. Would something like a 555 timer work for this, or is that silly? Would that also drive the audio? What is the simplest way to do this? My experience with electronics is very, very basic - nothing beyond playing with LEDs, soldering/unsoldering components, wire splicing, a super-simple Jacob's ladder, etc. Is this project too advanced for the time being? I'm not asking for the schematic to be built for me, just some direction - I don't know what I'm doing here. Help?

And secondly, would an integrator (R-C-Ground) work with that DC supply? Thanks in advance for you help and advice.
