Then pull out those screwdrivers, or... wallets, because there is an interesting use for them!
Step 1: Parts: the easy part
2 yel,vio,brn resistors
Step 2: Assemble
i will give a schematic and for advanced viewers, instructions
Step one connect the infrared phototransistor to the NPN so it will amplify it
connect the led to the transistor so the amplified current will flow through the led
(remeber to use resistors)
Step 3: Grab your tv remote!
Step 4: Extra: other uses
there are various experiments to try with this eg point a different red LED at it and see if makes infrared waves, how about a flashlight?
This was just a fun experiment to do when your bored and has no actual usage and if it does its by coincidence i apologize for your wasted time XD
