Driving High Power LEDs

The LED brightness is kept constant by this constant current source circuit no matter what power supply is used making it ideal for high power LEDs for any number and configuration.

Two Player Pong Game Using 5x7 Dot Matrix

The project has been assembled on a breadboard to create a classic pong game where each of two players have to control the bouncer with two buttons connected to ATmega16 microcontroller.

Flicker Simulator for Lamp Flame

The project will be strictly used for incandescent lamps to create a flame flicker simulator or a lamp dimmer which may be turned ON/OFF using the switch on the lamp.

Stepper Motor Driver by AVR Microcontroller

The project utilizes scavenged stepper motors from disk drives or printers with some probing of an ohmmeter followed by some simple driver code on the microprocessor.

Controlling a Servo with PIC Microcontroller

Driving hobby servos using a PIC microcontroller is the main goal of this project which can also be used in other microcontroller projects.

Initial Use of AVR for Ghetto Programming

The project is based on one of the smaller size chips, the Atmel ATtiny2313 chip, which will be used to build up a complete toolchain consisting of compiler, programmer hardware and software, and some simple demos.
