PIC-Controlled USB Thermostat

The USB thermostat utilizes PIC18F252 to store all of the temperature change entries as a table in its EEPROM memory.

TV-B-Gone Device with Greater Distance

The project is focused on providing even greater distance that the TV-B-Gone device can reach in order to turn ON/OFF a television.

Temperature Controlled Electronic Relay by LM35

The project has been constructed for applications that require automatic temperature control while providing highly accurate thermal control circuit.

Automatic Dark Detection Circuit

The circuit is very simple that it was designed with only a phototransistor providing a control on a single LED which may be used for pumpkin lanterns.

Motor Controller with Adjustable Voltage

The project was designed for anywhere and anytime motor testing with the use of adjustable voltage on motor controllers to manipulate the speed of the motor during testing.

Ultra Infrared Receiver Via USB

This simple device is used to control the power ON and OFF of a personal computer with the used of ultra infrared receiver that is connected through the USB cable.
