Introduction: Easy Way to Test IR Module
Hi guys today i will show you that How to Test IR Module Everyone Need to first Make sure that IR module is working Perfectly or Not before Soldering .
Components Required :
Resitor 470 ohm,1k
Red Led + Buzzer
Two 10uf capacitors and One 100nf capacitor
Step 1: Circuit Diagram
The circuit Diagram is very simple If it,s hard to find 9v Power supply so it,s ok you can Connect 12v Dc power Supply further it,s Duty of LM7805 to Regulate the Dc voltage to a 5V constant dc Voltage .
Step 2: It,s Working
***MUST DOWNLOAD THE VIDEO ***
When you Put your Hand in front of The IR module it will Make the O/p pin Low to 0v and you will not hear a Buzzer sound but when you Remove your Hand the Buzzer will start Sound because now IR module Output pin = 5v Now we can Receive 5v at the base of the BC547 transistor .
We have a be nice policy.
Please be positive and constructive.
