Arduino and PIR motion sensor based automatic multiple light control system. Room light on - TableLamp off. Room light off - TableLamp on. Perfect device for study. Control things by just waving at them. I've  built a PIR motion sensor based automated light / Appliances project which can be found  here . This project is a bigger version with relay to control 220V lights. FEATURES-  Table lamp ON main Light OFF  Table lamp OFF main Light ON PARTS YOU'LL NEED - Arduino pro mini (or any board) 2 Channel relay module Buzzer PIR motion sensor 220v to 5v converter wires hot glue THE CIRCUIT DIAGRAM: Making the project: I've  built a PIR motion sensor based automated light / Appliances project which can be found  here . This project is a bigger version with relay to control 220V lights. Just added the lights switch wires to relays and powered the arduino and relay module using a 220 to 5v converter...

An automated Medicine Reminder that reminds you to take your medicine in time. For any query please mail at ashraf_minhaj@yahoo.com PARTS YOU'LL NEED: 1. Arduino pro mini -5v 16mHz 2. Buzzer 3.  330r/220 /1k resistor 4.  Vero board 5.  Female pin COD E: After restarting the Arduino it waits for 24 hours and then keeps on buzzing. Change the delay as your requirement. It won't stop untill you press the restart button, which means you have to get to your medicine box in order to stop the alarm. And after you press the button it'll again alarm after 24 hours.  24 hours = 24 * 60 minutes                = 24 * 60 * 60 seconds                = 24 * 60 * 60 * 1000 mili seconds (1sec = 1000 mili second)                = 86400000 ms /* MeDuino: Automatic Medicine reminder. * By Ashraf Minhaj www.ashrafminha...
