Simple IR Proximity Sensor using using NPN transistors / Complete process

Hi friends, in this video I'm going to make an IR proximity senser using IR Transmitter & IR Receiver with C945 Transistors on Breadboard.
Circuit Diagram is available in video.
Components Required for this project 👇
C945 Transistors 2x
IR Transmitter 1x
IR Receiver 1x
LED 1x
220 ohm Resistors 2x
Jumper wires
Breadboard 1x
9V DC Power Supply

After installing the LED I connected a 220 ohm resistor to the base of the second transistor and it was connected by mistake, but I fixed it and connecting it to the IR transmitter and the LED ..
Please ignore this mistake,, Thank you very much.
