I purchased 2 different kinds of servo motors for my robot Arduino project.
One on Amazon:
Four on Ebay.
They both arrived quickly.
I tried using the four on Ebay first.
“4PCS Digital MG996R MG995 High Torque Metal Gear Servo For Racing Futaba JR RC”
Eventually the pwm servo driver board I was using started smoking. I sent the people who make the board, SunFounder an email:
“I bought a SunFounder PCA9685 16 Channel 12 Bit PWM Servo Driver for Arduino and Raspberry Pi on Amazon for 11.99.I followed the instructions here:
After awhile, the 9685 board started smoking. I was wondering what it could be? I was trying to adjust the min/max of the servo and noticed every time I restarted the power it would rotate a bit in one direction consistently. I think that’s a bug in the software. I Googled and found someone who had the same problem.
I also have this problem:
I was also wondering if the voltage from that wiki page could be too high?
I think without some help if I bought another 9685 board it would just start smoking too and be ruined.
It did work for awhile, but I tried running the example code where you could set the min and max and it knocked up against the metal not being able to move.
I attached a picture. The smoking came from the component to the left of the word power.”
