hi,
my goal is to control 4-5 servos with 1 Arduino Nano, what needs pwm.
for servos VarSpeedServo.h is included.
For first tests servos will be controlled for 2 positions (model railway rail switches) by buttons, where JC_Button.h is included.
The pins 5,6,9,10 (D-Side) work well for PWM, but 19,20 (A-Side) dont.
Is there something needed additionally to bring A-Pins to work as PWM-Output for Servos ?
my code `
