By using this Circuit, we can increase the range of emitted IR radiation up to 100cm. It means we can increase the IR transmitting distance multiple times using this Long Range IR Transmitter circuit.

The Audio signal will be transmitted through an IR LED from the transmitter circuit; the IR signals will be then received by a photodiode which will be placed on the receiver circuit. The audio signal ...

const int IR_SEND_PIN = 3; // Define the Arduino Nano PWM pin for IR LED void setup() { Serial.begin(9600); // Start the Serial Monitor for debugging IrSender.begin(IR_SEND_PIN); // Initialize the IR ...

Since his AC unit had an infrared remote control, the first thing [Giulio] needed to do was come up with a way to emulate it. An easy enough project using the ESP8266 and an IR LED, especially ...

IR Remote Switch Block Diagram The main function of this remote control switch is to control any load (TV, Radio, Stereo, Fan, Light, etc.). In this circuit, we are using one switch for operating the ...

Here is the circuit of an ultra sensitive IR receiver that can be used to switch on various AC devices through an IR transmitter. It uses the Photo transistor L14F1 to detect IR signals from the ...

This infrared alarm barrier can be used to detect persons passing through doorways, corridors and small gates. The transmitter emits a beam of infrared light which is invisible to the human eye. The ...

An IR transmitter/receiver pair are positioned on either side of the fan. When the blade passes in between then, the receiver shuts off a transistor connected to one of the Arduino’s external ...
