RC Tank - Transmitter (gun sytle) conversion kit

Well, this is my mod on the RC Tank by Staind. I wanted to control the tank with a so called gun or stick RC transmitter (Easy of use for "all" ages). To do this i run the signals thru a Arduino and translate them to "tank" drive.

If you use a Car ESC i added a bracket to hold that very neatly, its mounted by the 2 mounting points already there, you only need longer screws ( i used some leftovers )

As you can see in the parts i added a PING sensor to mine but i left this out of the code for the thingiverse version. Mainly fore easy of use, if you know what to do by all means print the corresponding parts and "hack" it in there.

#CAUTION

1. the arduino bracket has "wrong" hole spacing but one hole will always line up.
2. in the drawings i used a 2-way switch but you NEED a 3-way switch (cant find the fritzing part).
3. the Lipo is of course you're RC Lipo battery the one i added is just for illustration
4. the + and - from the Lipo ONLY GO TO THE ESC'S !!!
5. A V-Tail mixer is also a solution for this if you only want the tank drive. Al thou i prefer the options Arduino gives me you might not.

There is a switch ( 3 way switch) to enables speed limiting, you can leave it completely out and it will go on full power, so its optional.

I did my best to ad as much commentary to the arduino code... youre able to tune the script to the receiver by the config section.

Just as a heads up (as OGER found the solution for) the pinout for the interrupts is somewhat complicated. Check the pinout for your board and connect accordingly but use the interrupt values within the code. On the pinout documentation the pins are labeled INT1 and INT0 there in "pink" and are called "Interrupt Pin". So if you use INT0 and INT1 there is no need to change anything within the code.

Arduino UNO
Interrupt Pin 0 = Pin D2
Interrupt Pin 1 = Pin D3

Arduino Nano
Interrupt Pin 0 = Pin D2
Interrupt Pin 1 = Pin D3

As requested i added the code i use with the ping sensor please understand that this is experimental it works but needs tuning so use at your own discretion.

It so happend a fellow 3d printed tank was made close to my location, and after one evening the electronics where done. So added some pictures of how it can be done (actualy i am a bit jallous now as mine is not as needly ;-) )

On request a arduino code file for drone esc's no break no reverse. And disclamer code not tested (i have no way to) use at youre own risk!
