Flashing LED: The simplest circuit to start with, it uses 555 Timer to give a clock pulse to a LED. This clock pulse is further varied by using potentiometer. In this Project, I have provided three different modes of Flashing an LED.
Flashing Rail road Lights: This project flashes two LEDs alternatively with equal intervals of time so they act like a Model Railroad lights
Fading LED: A Circuit that fades an LED on n off using 555 timer.
LED Dimmer: This project is used to control the brightness of LED.
Traffic Lights: This project is a UK traffic light system. Which operates for 1-7 minutes by adjusting 1M potentiometer. Appropriate outputs are combined with diodes to on/off the particular LEDs.
1-10 7 Segment Display Counter: By using 7 segment display, this circuit counts from 0-9. Using 555 timer, 74LS90 & 74LS47 Ics
Random LED Flasher: This Project flashes 8 LEDs in random manner. The speed of random flashes can be changed by simply changing the Capacitor. This pattern is mostly seen on Christmas trees and other type of decorations.
LED Chaser: This is actually a decoration circuit used in Christmas trees or in the Indo-Pak marriage halls. Its hard to explain what it does. Checkout its video =p
LED Chaser Using Arduino: Its same circuit like above, but I have used arduino in order to do it so. Using Loop command and to show how a circuit is made simpler using programming and know the power of Arduino =D
RF Radiation Detector: The most famous project on this site, This Project is linked by many of the Electronics Websites. This tiny circuit has no voltage source, it rather converts Rf radiations into Electric current and glow an LED =D This is most awesome project on this entire site! Must try this. It wont take more than 5 minutes to make once you have the 4-5 electronic parts.
Clap Switch Circuit: This Circuit is sound Sensitive! sound could be any high pitch like Whistle/Clap or whatever. It glows a LED when you clap =) check it out the working in the video.
Shadow Detector Alarm: This is shadow detector circuit, when a shadow falls on LDR. The buzzer sounds! The LDR sensitiity could be set to any light source by varying potentiometer. The buzzing sound time can also be varied by a potentiometer. This can be made as a Alarm if some one enters your room. Check it out how!
Light Sensor: This Light sensor is a circuit which senses light, unlike the shadow detector alarm. We can make it either Shadow detector or Light detector by swiping just two wires in the Comparator IC
Light Sensor Using Arduino: Same circuit, but using Arduino code for simpler and messing up the if else statement in there is really fun! try it out
Controlling DC motor using Arduino: This is actually controlling speed of DC motor with potentiometer using Arduino, where DC motor is supplied by PWM output of Arduino.
Basic Programble Robot: The simplest Robot you can make out of Arduino, and a H-bridge IC. This page show you how to make your First Robot Completely programmed by arduino. Believe me, making robot with arduino is really a piece of cake only if once you have a complete understanding of things…
Line Following Robot using Transistors: This is the simplest robotic circuit that you will ever find anywhere around internet. It uses just transistors nothing more complex than that! This LFR uses Differential drive method. This Robot will follow a Black like drawn on a bright surface. Its too simple, You got to use DC geared motors in there, otherwise it might dont work because of not enough torque!
Line Following Robot using 555 Timers: A white Line follower using 555 timers. Using Pulse width modulation it has better accuracy and does not shag like the one made on transistors. This Line Following robot has little bigger circuit but yet simpler than you find over internet. You also have a breadboard arrangements, so that makes it more simpler and easy to make
Resistor Color Code software: A heavenly software for the Electronics hobbyists to read a resistor color code on your finger tips. Just select the colour bands and you get the value right away. This page and video also shows how does this Resistor Color code works
Simple DC Current Generator: This was actually something I made when i was in High school, it is converting mechanical energy in to electric energy. This is small experiment to understand how does wind turbines and water mills generate power.
