I have a VEX Robotics Receiver Module (Link,) and I was wondering if I can use it with my Arduino Uno R3. I have a few ideas where to start. For one, I know it uses PPM to communicate. I metered it today, and it was getting 5V from the VEX PIC controller. My first guess would be that you would wire the RX directly into one of the Arduino's interrupts.
Thanks to those who can help. :)
