Raspberry pi 使用按钮作为伺服开关

Question

I have a raspberry pi using pigpio to control two servos with two buttons. Right now I have to hold the button to make the servo move. I want the buttons to toggle the servos between the two positions, but my attempts fail.

I'm on mobile so i put a picture of my code, sorry I couldn't paste it. Code Picture

Note: the commented code is from when i was using gpiozero to control the servos, but it caused jittering so I switched to pigpio. The comments are there just in case I have to switch back for whatever reason.

Answer 1

To toggle between positions you need to know when the positions are reached.

• Do you have limit switches?
• Can you measure the increase in current when the motor reaches the limit?
• Can you send the motor to a position by setting an angle?
