I have understand all the connections but RC transmitter. for my control, the trainer signal is input by 3.5 mm headset interface. from the project， I am confused that how the ppm signal output from the arduino nano is input to the RC transmitter? Does it directly connect 3.5 mm to the pin on the arduino？
