DC Motor Servo Tester - An Update
For the user interface, I’m using an LCD and button interface that was originally meant as a replacement part for the ANET A8 3D printer:
It’s an HD44780-compatible 20 character x 4 line display, running in 4-bit mode, and uses a simple resistive network for the buttons, allowing the sensing of button presses just by polling the value of an analog pin:
The UI will be navigated/controlled via the buttons. The information about the motor, servo, or ESC under test (such as voltage, amperage, temperature, etc) will be displayed on the LCD.
