RC Control and Arduino a Complete Works 1. Steps. This final step is a culmination of all previous topics and my tank steer code. I made the tank steer code to only use the right thumb stick of the transmitter to then control two CR servos. Remember that my TX is set to mode 3 and I dont have any channels reversed. The right thumbstick is channel 3 for the horizontal axis and channel 4 for the verticle axis. Following is my sketch using an Arduino UNO instead of the MEGA. Im using differnt servo limits that enable a micro servo to move a full 1. Make sure to thank my wonderful model Sid above picture for being such a good sport while Ive been using him to refine my program. This will sketch will read all 8 channels of a RC receiver and input the values via serialmonitor. Programmed for the Arduino Uno and Adafuit Servo Driver Boardpins A5 SCL and A4 SDA. My transmitter is also set in mode 3 so the right thumbstick is as follows Verticle Axis Channel 3.

The fourth quadrant doesnt work and I have yet to get working. It wasnt that big of a problem as this is a proof of concept robot in working with RC control and Arduino before I move full scale. Let me know if you have any questions and I will do my best to answer and update accordingly. Please include the step and some detail explaining your problem to help me get on the same page with you.
