Step 6: Circuit (Josytick Controlled)

Here you can see the circuit of the controller and the robot's circuit. Build these two with the help of your soldering iron.

On the transmitter, so on the joystick's circuit the Arduino Mini Pro measures the incoming signals from the joystick and the potentiometer than transmits these to the Bluetooth module or RF module in bytes. The measurement happens at analog pin A1, A0 and A2. The 5v step up module ensures the voltage for the micro-controller and the vharger circuit charges up the battery safely. The serial communication module is connected to pin D3 and I used a 1k and a 2k resistor to decrease the voltage to 3.3 volts.

On the receiver, I mean the robot's circuit the Arduino UNO gets the bytes from the RF or Bluetooth module and the controls the motors via the motor shield or turns on/off the lights. The camera is powered up by the 3.3 volt regulated pin of the Arduino. The serial comm. module is connected to pin A0.

<p>Great idea. I got excited to use the FPV Wifi camera you link to for another project so went and got a couple off Ebay. Unfortunately what you link to is not a Wifi camera. May have been at one time and is 'advertised' and described by the 'store' as Wifi but they obviously either don't know or don't care what they are selling. Caveat Emptor to anyone else thinking of this.</p>
<p>Yea, I also got that camera and it does not seem to have any wifi. I also can not figure out what the wires are. When I open it up to look the yellow is marked ad positive and red as negative. Nothing is happening when I connect red to 3.3 V and black to ground so I am not sure it is working at all anyway.</p>
<p>I did get that far. You figured out the same polarity I got. If you have the SD card installed and then connect the black wire to the 3.3V it will start recording video for as long as its connected to the 3.3V. If you 'pulse' it by momentarily touching black to 3.3V, it'll take a screen shot and store it as a jpg in a separate folder on the SD card. It also has and records audio with the video. </p>
<p>Dualism is a lie.</p>
Hi I'm having trouble buildibg it. The uno-board (receiver) seems to receive signals from the transmitter (blinking while turning the joystick) but the motors dont run. Is it posdible that this joystick is not compatible?
Plz need help <br>
<p>Hello, yes I am here.</p>
For how many distance the camera work? It is work on wifi? <br>
For how much the camera work? And it work on wifi? I need same wifi source to connect it to my phone?
Can i do it without programing skills? I can just copy the code and past in the prog.app?
Yes you can ☺
Hello i need your help with sonething please can i you with email or any app like facebook ,....? This is my email Roudyhazzouri2001@gmail.com
Thx :)
<p>Hi, AMAZING PROJECT, really loved it, want to try out something similar on my quadruped project,</p><p><a href="https://www.instructables.com/id/QUATTRO-the-Arduino-Quadruped-Robot/">https://www.instructables.com/id/QUATTRO-the-Arduin...</a></p><p>but i have used up all my pins for the servos, any suggestions?</p><p>thnx in advance</p>
Bonjour, <br>Bravo pour votre projet. Une question : comment avez vous branch&eacute; la cam ?<br>D'avance merci
<p>hey, thanks for all the links and step by step instructions. my parts are all ordered and are begining to come in the mail. I got the double gear box first..what ratio did you build the double gear boxes? they can be built in 4 configurations...12.7/1 or 38.2/1 or 114.7/1 or 344.2/1. I am happy to play around to see what works, but what did you use??</p>
<p>I found this just now and thought it might help.</p><p>https://www.pololu.com/product/114/specs</p><p>If you look in the different tabs (specs, faqs) there is enough info to know what rpm each ratio will get.</p>
<p>Same here. My gearbox arrived today and I was wondering the same thing. The ratio used in the video looks good to me, so I was wondering which you used.</p>
<p>wow nice</p>
<p>amazing! voted all 3!</p>
good work
<p>very nice!!!!</p>
<p>Magnifique! Excellent Build!</p>
<p>wow. This is very good. </p>
<p>a tank controlled with brain??cant imagine what a full size will look like lol!</p>
<p>Du bist mir wirklich am besten, ich bin sehr stolz auf Dich! Viel Spa&szlig;, Erfolg und Ausdauer! Ich bin immer bei Dir Schatz! :)</p>
<p>Dankesch&ouml;n Kicsipuca! :) </p>
This is the coolest thing I've seen ever
<p>Thank you very much! You can give me a kindly Vote. ;) </p>
<p>would you be willing to sell this to me on ebay?</p>
<p>Sorry :) I can't...</p>
<p>verry nice</p>
Oh this is a verry nice project.I vote for you:))
