Add an output device to a microcontroller board you've
designed and program it to do something
Servo motor
I tried to make a servo motor system which can change the angle
relative to the value of a force sensing resistor.
Servo motor.
Firstly I checked the servo motor by using the Arduino.
Screen capture of Arduino IDE. Example code.
I can see the servo motor rotates in a direction when I touch the sensor, and then the servo motor rotates in an opposite direction on taking my finger off the sensor.
Wiring.
Then, I milled a circuit board using CNC router and soldered some parts to the board.
Milled circuit board (hello.servo.44).
Soldered board and servo motor.
Liquid Crystal Display (LCD)
I also tried to make LCD module.
The PCB board (hello.LCD.44).
Results. "Hello to the world"!
