A photocell or photo resistor is a Light Dependent Resistors (LDR). LDR’s are sensors that detect light. They are small, inexpensive, low-power, easy to use and don’t wear out. Overview A photocell or photo resistor is a Light Dependent Resistors (LDR). LDR’s are sensors that detect light. They are small, inexpensive, low-power, easy to use …
In this project we are going to make a vibration alert system with ATMEGA8 microcontroller. This can also be used as a theft alert system, for that we are going to interface tilt sensor with ATMEGA8. A tilt sensor is shown in below figure. We can see there is a cylinder in the picture, in that cylinder there will be …

Would be interesting if we could make our microcontroller to sing for us not just beeping or blinking; this project is all about using the powerful AVR ATmega168 16-bit PWM feature to produce accurate musical notes such as playing the child’s favorite Twinkle-Twinkle Little Star song or we could say beeping with style. The principal we …

The servo motor is widely used in model hobbyist such as airplane R/C model for moving the rudder, ailerons, elevators and acceleration control or in the car R/C model for steering and acceleration control. In this tutorial we will learn how to control the servo motor as well as the simple close loop control algorithm …

Are you an electronic hobbyist? Then an adjustable power supply is a must for your various needs. This project explains how to make a LM317 based adjustable power supply unit with a digital display. Components Required 1. LM317 IC 2. Resistor – 240 Ohms 3. Capacitors – 0.1uF, 10uF 4. Potentiometer – 5k 5. 30V/1A Adapter (or a …
A couple of years I embarked on my own home automation project. It started off by building a server controlled 433 MHz transmitter build with an Arduino to switch lots of cheap PT2262 based remote switches. Later I added an Arduino based receiver for my weather station, hooked up the control contact of my EV …

In this post I will attempt to describe the steps I took to build the arduino based thermostat shown in the following videos. The first video was taken when around just half of the coding of the menu system was complete, but gives you a basic run through of the features. This second video shows …
I have loved making projects with Arduinos, but at $30 a piece your projects can get expensive. So I want to show you how you can make your own Arduino from scratch and save money doing it. Make your own Arduino for around $8. For this instructable I show you how to make one on …
