This project is a temperature monitoring and fan control system. It uses an LM35 temperature sensor to measure the ambient temperature, and an Arduino microcontroller to read the sensor data and control three 12V fans. The system has three LEDs that light up in different colors depending on the temperature, and a buzzer that sounds an alarm if the temperature goes above a certain threshold. The system is powered by a 12V power supply for the fans, and a separate power source for the Arduino. The LCD screen displays the current temperature in Celsius. The fan speed is controlled using a Pulse-Width Modulation (PWM) signal generated by the Arduino, which varies the duty cycle of the signal to adjust the fan speed. Overall, this project is a simple and effective way to monitor temperature and control fan speed in a given environment.
Materials Used:
Issues:
The setup for the fan only power one fan instead of the 3x 12v fan and I use a 12 power supply cord to power it. What should I do in order to power up the 3 fans.
