This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

The motor speed is controlled using pulse width modulation (PWM), where ... and directional controls for the DC motor using an Arduino Uno microcontroller. 2. Literature Survey DC motor control is one ...

The values received for each servo channel are between 1000 (hex eE8) and 2000 (hex 7D0) with neutral sub trim setting, which corresponds with the pulse width in ... the receiver and the Arduino board ...

We will first interface the LM35 sensor with Arduino UNO to measure the surrounding temperature and relay to control the fan. We will then upload the conditional code in Arduino and check the output.
