Here is a circuit diagram of IR Led Transmitter and Reciever, you can easily make it because it doesn’t need any practice. You can easily make it with copying my IR Led Transmitter and Reciever circuit diagram. you can make it on a bread board (project board) or direct sold it to a silicon chip.

Materials for Transmitter:

• 3   1k resistors
• 1   2N3904NPN transistor
• 1    9 volt Battery
• 1 or more any color LEDs
• 1    IR led transmitter

Materials for Reciever:

• if you are using 2 AA batteries (3volt ) in reciever then use 100N resistor, but if you are using 9 volt battery then use 1K resistor in reciever
• 1 IR Led Reciever
• 2 AA batteries ( 3volt) or 1 9 volt battery
• 1   1K resistor or 1   100N resistor
