The thermometer operates by converting the sensor’s output voltage, which is calibrated and proportional to the measured temperature, to output cycles. The output cycles are transmitted in the supply ...

For those building their own remote controlled devices like RC boats and quadcopter drones, having a good transmitter-receiver setup is a significant factor in the eventual usability of their ...

The Infrared Remote Control Switch is a simple electronic circuit that uses an infrared (IR) receiver to detect signals from a standard TV remote and control an electrical load, such as a lamp or ...

The receiver is equally simple and also based on a CMOS 555. As long as the sensor picks up infrared light from the transmitter, the reset input of the 555 IC is held low and the buzzer is silent.

LoRa Communication: The LoRa transmitter (connected to Arduino) sends commands to the receiver module. ESP8266 Integration: The ESP8266 facilitates communication with a mobile app or web interface for ...
