I added some circuit examples for three tractors today, just scroll to the bottom of each page

Does that help?
Yes you have 6 analogue inputs on an Arduino Uno so that is six potentiometers, there are two per joystick so you can have up to 3 joysticks.
I am working on new code as I’ve made many changes to suit the new controller I designed and one change I plan to make is to change the tracked tractor code so that I can control it in the same way as the other tractors. The reason is that it makes the code more manageable when your controller has to deal with many different vehicle configurations and it will allow me to control the tracked tractors using the basic controller if I need to.
Hi,
This thread has code for the transmitter and the receiver used in a crane. It controls three motors, if you want to control a servo instead of a motor then add a servo in the normal way and use buf[1] as the servo value.
I am working on new code for the tractors and trucks at the minute which should have many improvements, I’ll be uploading that as a library next month when I finish it. This will help you and also contain many examples.
Thanks for the links, I am not very familiar with these micro RC components so it is good see them and see how they are used. Excellent job on your conversion.
Funny I just saw that link somewhere else in this forum. It’s a good build he done a nice conversion with the sound and everything especially in such a small model. Very impressive.
Yes that is the kit I was thinking of, they are pricey but then again you are getting a nicely machined 4WD system for the price of around the price of three siku models so the question is would prefer four static siku models or one 4WD RC one 🙂 Thanks for the link, it will be useful a lot of people I’m sure.
Well a few minor changes and I think it will be good to go. I might add a IR receiver to help with decoding IR signals also as I’m finding that to be a useful feature 🙂
That is an amazing build, the detail you have finished the model with is just perfect. I think you sent me a link to those differential before didn’t you, they were pretty expensive weren’t they? I suppose everything is in these hobbies but there is no denying it the end end result is amazing.
Welcome to the forum, I’m glad you like the website and videos. I don’t think I’m quite an expert yet but I’m glad to share what I’ve picked up over the last few years.
Sounds like you have a good build going but what do you mean “close and open the differential via a relais”? Are you using four N20 motors or a differential like you used in your steyer truck?
Sounds like you have great experience with different types of RC vehicles, I definitely lack knowledge in normal RC vehicle design. I kind of went to RC from the hobby electronics side rather than starting with the models and than learning the electronics.
I actually received the version 2 prototype PCBs yesterday and have assembled one and started testing. So far so good but I have a lot of code to write to do everything I want but the PCB seems good, I have a few minor change to make with holes sizes to make assembly easier but no huge changes. I am building a library so basically anyone who buys the controller can download my library and upload it to their controller immediately getting exactly my controller. Or if they prefer they can of course start from scratch themselves. I’m hoping to launch a kickstarter next month and by the end of the kickstarter I’ll release V1 of the library and just update it as I update it for myself or if others give me suggestions on how to improve it.
I will have control for all my normal vehicles, I’m trying to get the infrared working to control siku control 32 models but that is not easy. Also I’m trying to get control of some syma IR helicopters I have and then I have a plan to make a sort of drone from an old RC helicopter and maybe so small robots made from old RC cars, just ideas so far. Then I’m trying to include some basic features just because they should be easily done with the Arduino so I have IR remote code to control TVs other IR control things which should allow me to test the IR is working before moving onto the complex IR things like the helicopter and control 32. Also I added some basic games pong, snake and brick. The snake game works really well so far, the others aren’t great I might make pong two player because it’s a bit crap at the minute and the brick game isn’t working at all yet. These are minor additions, I spent about three or four hours to add the games whereas I’ve spent a lot of time trying to get the IR helicopters working with no success yet.
The speed of the radio transmission is another thing I need to test, I’m planning to add a tool where you set up a node and select the tool from the menu on the controller and it reads out various performance data. That’s the plan but I haven’t got there yet.
I do have a prototype for a board to go inside the model, it basically does all the wiring for the TB6612FNG and the smaller NRF24L01. It uses a PCF8574 to to control the direction of the motor driver so it can control two motors and put the driver into sleep plus adds 3 extra outputs while only using 4 arduino pins. I haven’t receiver the PCF chips yet though so can’t test that properly, I have some through hold versions so maybe I’ll do a bodge just to the test the PCB is working fine.
That reply got very long very quickly 🙂
Yes the code can control two or more RC cars so it is different to your code, I’ll make a start on some new code for you since I think I see an easy way to do what your want. I’ll post the code here because it’s quite different to this code.
