| Feb 1, 2021 at 8:37 | comment | added | Justme | How much current does the servo pull, and is the 2N2222 able to handle such current without too much voltage drop? Also, the circuit is switching the servo GND while leaving the VCC, so depending on the servo PWM pin interface, it may try to power up via the PWM pin. Which state you leave the PWM pin when the motor is unpowered, high, low, PWM, high-z? What is the PWM signal voltage, 3.3V? | |
