Hi, So in computer engineering I've got to make a arduino based car, I've added a whole bunch of features such as IR tracking, obstacle avoidance(proximity sensor), optical tracking(follow a black line), and remote control through an android based phone. Since I'm a total newbie to technology I'm having trouble. I would appreciate it if You guys can point me towards resources and arduino libraries(for coding) that will work for me. Right now for coding I've only got basic pseudo-code setup since I do not know what libraries to use. I have searched up many sketches online and looked at them but didn't really understand any of the code. Here's the basic pseudo-code I got setup on the things that I've got to work on: DC Motor (4 of em for the wheels) (I also plan to add a stepper motor for turning right and left so if you could direct me on that as well) //Import necessary library //Setup the motors and pins //If signal for forward received //Code for moving forward //Set speed //Else If signal for backward received //Code for moving backward //Set speed //Else If signal for right received (keep turning right till stop signal received) //Code for moving right //Set speed //Else If signal for left received (keep turning left till stop signal received) //Code for moving left //Set speed //Else If signal for stop is received (Should we slow down to a stop or just stop?) //Code for stop //Set speed IR (I've got transmitting and recording diodes) //Import Library //Declare Pin for the IR Sensor //While loop: Move Right //If IR signal is received //move forward //Else //Jump back to top of loop Proximity Sensor (obstacle avoidance mode) (I might either use the one from Lego kit or buy a separate one ) //Import Library //Declare Pin for proximity sensor //While Loop: Send out sonar(echolocation or whatever) every second //Is there any obstacle? //Yes, turn right so many degrees, and go back to while loop //No, move on forward at set speed //If you’re surrounded and cannot exit send out a message through flashing LED's ________________________________________________________________________________________________________ I'm not asking for the code or for any of you to do all my stuff for me, I'm just asking for direction and resources. Thank You

First off, this is a question about speakers sound quality loudness and all that stuff, it doesn't really have to do with any math or equations, just experience. So I want some sub woofers, and after looking around I have determined that there are cheap ones, and very expensive ones. Now, if I get a fairly affordable 15" (med quality) will it be louder/better than a 12" one that costs $900
Question by jj.inc | last reply
I bought a car battery just so I could take it with me camping and charge my cell phone. Here is the problem: car powered devices are designed to be charged in a car while the car is running. The voltage of car power is 14.4 volts and the voltage of a fully charged car battery is 12.6 volts. The car battery will charge my cell phone because it is low amperage and does not drop the voltage very much (only if the car battery is mostly full), but if I try to connect my inverter and power higher-amp devices the inverter will beep and not work because it senses low voltage. One way I can get my battery to work is if I had a DC step up transformer. A car battery ranges between 0 and 12.6 volts. I need something which can supply a constant 14.4 volts as the battery is drained. Another option is if I got two batteries and hooked them together in series for 24 volts. If I did that I would need a transformer which could convert 24 to 14.4 volts as the batteries drained. So what is the best way to do this? This is for my camera drone: a DJI Mavic Air. If I could charge my drone batteries with a car battery I could fly a lot longer. Thanks-Jacob

Ok, so my back speakers of my car aren't working properly... they were working good for a while but aren't as of today... I brought both of them inside and connected them to a household stereo and they both work perfectly in that scenario but one works a lot better than the other in the car. speaker A works well when it is place on either the driver side or the passenger side, speaker B sounds weak and tinny when on either the driver side or the passenger side... Please help me out, i've been racking my brain trying to figure out why they arent working correctly in my car when they play perfectly in my house... and they are car speakers not house speakers

Hello! I am new here. I want to know if i can connect this type of speakers ( http://m.jbl.com/products/GTO609C_JBL_US ) to this amplifier( http://www.sony.ro/electronics/amplificatoare-auto/xm-n502 ) or with this one ( http://m.jbl.com/products/GX-A3001_JBL_US?skuId=GX-A3001_JBL_US&searchMode=regularProductOnly&sCatId=cat140033 )? I want to mention that i want to buy two pairs of speakers. If no, what amplifier do i need (may i increase the impedance of the speakers instead of changing the amplifier?) Thank you!

I am interested in building an R/C car for the first time but i don't want just a standard bought kit i was more interested in buying all the parts individually can any one suggest where i start and what parts will be needed do i start with the motor or the chassis i really don't have any idea. So if anyone can give me some serious direction and helpful information on how to start and possible parts that would be great. Also could i just purchase an instruction manual for a kit and buy the parts individually instead of the kit and upgrade certain parts. thanks very much and no clever comments about how to use google my self i have tried but it just keeps sending me to self build kits and this forum site with other questions about self build kits thanks again

Ok so I work at a car audio shop as an installer and I see so much different stuff and do a lot of custom stuff on cars.. Ive seen a lot of cars that are keyless.. its just a key fob. when you have the fob in your pocket the car knows you are there and lets you start the car with a push button... that stuff is at least 5 years old.. now the other day a new z07 corvette came in for work and the guy handed me a fob to bring it in the shop,, nothing new at first,, but as I approached the car I heard the locks click,, so I stopped and walked back a few feet and I heard them click again... this thing is unlocking and locking on its own as I get near and away from it... And it still gets better.. after walking to and from it a few times to confirm my suspension I finally opened the door... the dash was flashing and it said welcome technician. the key I had was a valet key.. the other key fob I had welcomed the owner by name... this is really cool... I needed both fobs because I was putting a remote starter on the car and both keys are required to program it.. the valet key I had also turned on the traction control and the car wouldn't go over 40 mph... that's a lot from just a key fob... NOW FOR MY QUESTION HERE.... Is this done with rfid or some sort of proximity sensor on the fobs?? I want to build one for my car but just for the locks and push button starter... but I want to retain the factory key also..any ideas or maybe a link to an instructable?? ive searched them but cant find one for my purpose.. lots of rfid stuff though..

Dear all, I have a Skoda audio system integrated into my Skoda which has a cd reader plus a cd changer, but only a CD button(no AUX available). I would like to stick inside the audio system a Bluetooth receiver so I can listen to music stored in my phone. The goal is to solder a Bluetooth receiver to the audio system without loosing the cd functionality. On top of that I would like to be able to change from one source to the other without having to use an external button like a 3PDT switch. Thanks in advance, Pedro

Question by redsuit09 | last reply
Hi everyone, I am at a dilemma, I have 2 old PC stereo speakers, and since the rear set of speakers in my car are broken, I was thinking it was an easy transplant. However, when I took them apart, I saw that these speakers are 9V, and the car ones are (obviously) 12V, so I was thinking if it is going to fry them right away, or is it going to sing for some time and then fry them OR if it is going to be just fine. Also, these are a bit smaller (65mm in diameter) than the car's original ones, and since they are a generic brand and have no wattage rating inscribed on them, I am thinking that they require less W to power. Since the car ones are about 50W and my stereo can supply 4x50W, would that cause a problem one day if i uknowingly cranked up the volume, would that fry them aswell? I am not using anything big, just a simple stereo, with a simple output, no special equipment whatsoever. Thanks ahead everyone! EDIT: I just looked and found an inscription on the transformer in the back of the main speaker: I/P 240V ~50Hz O/P 9V ~500mA That gives me like, what 4.5W? Is that each or altogether? I am thinking these are too old/weak for this :o

Motor-manufacturer Nissan have announced a Â£200 million ($330 million) investment in a factory intended to produce lithium ion batteries for electric cars.Along with the news from Nissan, Peter Mandelson (Business Secretary) said a "low-carbon economic area" would be established in the North East.As part of the project, 750 charging points would be installed across the region and a training centre specialising in the manufacture and maintenance of low-carbon vehicles would be set up. "The North East has distinguished itself as the first specialised region for ultra-low-carbon vehicles," Lord Mandelson said.The announcement from Nissan comes only days after its Japanese rival Toyota said it would start manufacturing the new Auris hybrid petrol-electric vehicle at its plant in Burnaston, Derbyshire from mid-2010.

Question by ARJOON | last reply
Hi, I have been trying to design a circuit to monitor my 12V leisure car battery, I'm thinking this should be fairly simple, but its been years since I did any real electronics. So the basic idea: Use the circular bargraph to indicate the level of the battery when a momentary push button is pressed the circular LED bar graph: https://www.sparkfun.com/products/11492 So the range of the battery would be something like 10.5V to 13.5V, there are 32 LEDs in pairs, so essentially 16. 1. So if we take the first LED pair, this should illuminate when less than 10.5V, so that should be easy, as long as there is some life in the battery it should illuminate 2. The next LED should only illuminate at the next step, 16 LEDs, 3V range 16/3= steps of 0.2V So at the following steps: 10.5, 10.7, 10.9, 11.1, 11.3, 11.5, 11.7, 11.9, 12.1, 12.3, 12.5, 12.7, 12.9, 13.1, 13.3, 13.5. So for 10.7V I guess I should use resistor before each LED. 3. The LEDs should light up after a momentary push switch is triggered, I would like this to be graceful, so the ring lights up smoothly one LED at a time as the voltage increases, I guess capacitors between the resistors and LEDs? This is the simplest way I can think of doing it, I have seen circuits which use a LM339 chip, but that can only monitor 4 voltages, perhaps 4 of these in series could do the job? http://www.electroschematics.com/7068/lm339-lm239-lm2901-datasheet/ I think this is the way to go rather than using inline resistor/ capacitor pairs? So I am a clear novice when it comes to electronics (but I'm enthusiastic), so if anyone can help me with this I would be more than happy to put together an instructables how to, something similar has been done before: https://www.instructables.com/id/Car-battery-tester/ In that example only one bar is lit, I want the other bars to stay lit. I can use Eagle to make the PCB diagram and get it printed, but I need to figure out what components I need and how to do it! Thanks for any help. Gary

browsing for parts, thinking about resting it on the window itself. just looking to see if anyone has any type of ideas? This is pretty much my plan at the moment but I have to find parts for it. http://i.imgur.com/FrIGm.png But with this plan I for see 2 issues 1. The arm would most likely swing from side to side when speeding up or slowing down 2. If you wanted to record the driver, the window has to be down for this plan so wind would seriously be an issue. You could solve the first issue by using 2 arms, but windows are curved so.. im not so sure about that.

Alright, so ive got this rc car, it runs off of a 7.2v battery pack and has variable speed and turning. it is not a hobby-grade car, but it is still something id like to hold onto. today, when i tried to drive it, i discovered it could not accelerate, forwards or reverse. it can steer fine, but trying to accelerate does nothing. ive ruled out the controller and the motor, which means the h-bridge and associated circuitry must be to blame. i tested the battery in another car of the same model (not mine), and all was well there. the h-bridge must be PWM controlled in order for there to be variable speed, so heres what im figuring: the motor is making a clicking noise when i pull the trigger on the remote, looking at the motor, it is turning very little and then stopping and then doing this again, at a fast rate. when it stops turning for that split seond it returns to the original position, because it has turned so little. i know the motor itself is fine, because i connected the battery straight to it and it spun up and turned the wheels. i have a feeling the issue lies within the PWM control. i cannot guarantee the receiver chip is fine but it seems kind of odd that it would be the part to fail; regardless i cannot find a datasheet using the numbers on the chip. if i were to try and look for an issue/failed part somewhere, where might you guys think i should start? there are a number of transistors on the board around the h-bridge, some capacitors, and a lot of resistors as well. i checked all the resistors inside the h-bridge and they are all the same value as the bands indicate, andthere are no corroded or cold solder joints. i plan to test the h-bridge on its own once i find a diagram i can reference to, that way if the h-bridge works i can rule it out and narrow the possibilities. if you need any more information please let me know.
