               IR Reactive LED's using ARDUINO microcontroller.(controlling single LED)

                       IR Reactive LED's using ATMEGA16A microcontroller(controlling bunch of LED)


Hardware used:-

1. LED's
2. IR pare (TX, RX)
3. ATMEGA16A
4. Resisters(220E)
5. Regulator(7805)
6. Power Source 
7. Plank  

          
                This is the project completely based on IR rays manipulation. As we can see there are bunch of LED's (IR and Ultra-while) placed regular fashion on the plank and this LED's are activated if and only any abstract passes over it. When abstract is placed on the plank with certain distance the IR rays emitted by IR emitter get Reflected by the abstract and this Reflected rays are detected by IR receiver and this whole process is monitored by a microcontroller (ATMEGA16A). As soon as the IR RX detects the reflected rays it will give analog information to my microcontroller. Now microcontroller converts the analog data to digital(ADC) and controlles the LED's with respective to the data. In this way the LED's are going to be controlled
