To a lesser extent single colour LEDs have the same problem. A blue or green LED might need 2.8v and red and yellow LEDs turn on at approximately 1.8v. If you are running your circuit with a battery and you expect it to work right down to 1.8v then you are going to need to get ...
(digital pin 12). This allows you to adjust the code to fit the needs of your radio system. You will have smooth 0-100% PWM control of both LED's and the neutral light will turn on when the control stick is centered. If needed, you can widen the deadband for Neutral, but doing ...
