matthewclso:
as well as 14 PWM outputs for servo motors I'll be using.
Servo motors don't need PWM pins.
matthewclso:
all of them work perfectly and don't seem to have been affected by overvoltage.So, why didn't it work?
As long as it doesn't break the sensor, 5V and 3.3V application should be practically the same, right?
Or does the MPU6050 only respond to 3.3V signals?
Dumb luck.
One module has to pull all the I2C data and clock lines low to transfer data to the Arduino.
But is only designed for two.
You MUST remove the two resistors marked 222 on 12 modules to make this work without a muxer.
Code is the same, but you shouldn't shove 5volt from the Arduino into a pin of a 3.3volt device.
