Arduino Tutorial: IR REMOTE FAN CONTROL WITH CODE
An IR remote fan control system works by using an IR remote to send coded infrared signals, which are received by an IR receiver module (like TSOP1738) connected to a microcontroller (such as Arduino). When a button on the remote is pressed, it transmits a unique signal corresponding to commands like ON/OFF or speed levels. The IR receiver demodulates this signal and passes it to the microcontroller, which decodes it using an IR decoding library. Based on the received command, the microcontroller then controls the fan—turning it ON or OFF using a relay, or adjusting its speed using a TRIAC-based phase angle control (for AC fans) or PWM (for DC fans). This system allows wireless fan operation without physical switches, offering convenience and automation in home or industrial environments. https://docs.google.com/document/d/1S...
