I Built a Test Bench for Motor PID Tuning

Building a compact test bench for experimenting with a DC motor encoder and PID control.

In this part I assembled the encoder sensor, added an LED indicator for visual feedback, mounted everything into the 3D-printed frame and connected it to the microcontroller.

Now the hardware is ready for testing:

• Encoder feedback
• PID control
• PWM response
• Motor tuning

Next video — testing the encoder and tuning the PID controller.
