Hi All,
I'm new to electronics. I'm having Arduino Uno. I have to use 10 servos for a bot. I researched around this forum and found out that's not possible if I use shift registers and servos need PWM for input.
I tried the following scenario.
-
Connected Arduino PWM (9) pin to one of the breadboard terminal. By this way I can supply PWM to Servos.
-
Used the Shift Registers pin as +ve to Servo and grounded servo as well.
It doesn't work any way. But when I just connected to constant power supply to servo, it works.
I thought the Registers where not able to provide enough supply voltage to it and used relay with external power supply. Input to relay comes from shift registers. It also doesn't worked.
I want to know what have I done wrong?
Thanks,
Santhosh
