DC Motor Controlled by H-Bridge Relay

A reversible DC motor can be controlled to spin clockwise and counterclockwise using this circuit which only has a single switch for single control signal.

CNC Machine Based on Arduino

This homemade CNC machine is the second version which uses mostly off the shelve parts where every part is allowed for some adjustments and the different design makes it easier to be built.

Controlling Servo Motors with OOPIC

The controller project utilizes oServo Object of OOPIC to control RC servos by focusing on 5 properties including the I/O line to use, the position of the servo, the mechanical center of the servo, the rotational direction of the servo, and refreshing the operation of the servo.

USB Interface Used for Controlling Stepping Motor

Controlling some devices through USB interface is being demonstrated on this project with Delphi 6 used to program the PC host software.

All-In-One Remote Designed for Camera

The project aims to produce a versatile and portable photographic accessory all-in-one remote that can be carried within the camera bag and combines a number of useful features to provide capabilities during field, home, or studio photography.

Arduino Temperature Controlled PC Fan

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor.
