12. output devices (Apr 16, 2014)


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"!
