Now I am going to instruct how to make an IR Remote Tester with less number of components.
Lets Get Started..
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Components Required
Step 2: Circuit Construction
Connect IC 7805 Ground,Output pins to GND, Vs of Tsop1738 respectively.
Connect a 100 Ohm resistor from Vs pin of tsop1738 to +ve pin of LED and -ve pin of LED to output of tsop1738.
Connect 9V battery +ve to Input pin of IC7805 and -ve of battery to GND of 7805
Circuit Construction Completed ..
When you press any button of IR remote , the LED in the circuit blinks.
Datasheets of IC7805 , TSOP 1738 is attached.
