Move your Hand around - Lights ON, move hands over again - Lights OFF, sounds cool  right? Today we'll be making an automatic system to control appliances by hand gesture or Motion sensing using just Arduino and PIR sensor. In our project we'll make an Emergency light that lights On / Off by just moving your hand around it. In another word gesture or wave controlled light system. This can be used as an emergency light - when you reach home it'll automatically switch the lights on. So  our goal is to make a system that switches on once you wave at it, and switches off when you wave it back again. There's Some issues to keep in mind before you'd work with PIR sensor. PIR doesn't work properly  for  at  least  one  minute when starts . PIR output value is always 1  for  some  seconds. It some times doesn't read motions. T o Solve that I've made a simple algorithm that's explained  Here . Circuit Diagram ...

An Arduino Automated Car Parking System that is too easy and too fun to make. When a car arrives it shows the number of empty slots (if available) and then opens the gate. if there is not any empty slot then the gate does not open.  Amazing thing is that the whole project can just be POWERED using a POWER BANK!! Watch the video for the full tutorial. Note: you can use display instead of my hand made led sign display. Now lets get started. Step 1: Parts Arduino  - any board Infrared proximmity sensor  (pic 2 & 3 - both are functional) 330r resistor some  LED 's Servo motor  - any model or size you wish. Step 2: Making the LED Display To make this  LED display  I have used a piece of bredboard then soldered the LED's and the 330r resistor. Then j...
