In this, I have designed a circuit to control the speed of a dc motor using the input from a Temperature Sensor (TMP36), BC547 NPN Transistor and a Zener diode (IN 4731A). The input from the sensor is ...

This task turns an Arduino UNO into a simple thermometer using the TMP36 temperature sensor. The system detects temperature changes and provides a visual indication using three LEDs: 🟡 Yellow LED ...

This isn’t about connecting a temperature sensor in your Arduino. This build is about using the temperature sensor in your clock.
