Remote Control Projects Using IR and RF

Two communication links consisting of IR and RF are being used by this remote control which is subdivided into three parts as separate boards including RF transmitter, IR transmitter, and IR/RF transmitter.

PCB Business Cards

The extreme business card project is created with two experiments consisting one in the form of a key ring torch and one that dials by itself.

PIR Motion Sensor Made by Parallax

The Uber Tracker is a real-time GPS tracking device in which the GPS coordinates are obtained and broadcast over the cellular network.

PIC Based Electronic Dice Project

Different PIC microcontrollers can be used such as PIC16F84, PIC12F675, PIC16F690, or hard TTL logic, to build this electronic dice on prototyping breadboard.

Building Color Sensor from Reversed LED and Op-Amp

The project illustrates how LEDs provide current flow from light when put in backward position.

Wireless RF Transmission of Temperature Reading

The project was created to measure temperatures of remote objects with the use of wireless RF transmitter using TXM-433 module and the receiver uses ATmega8 SILRX-433 with connection to PC through RS232 port.
