Temperature Controlled Fan
A simple project using microcontroller AT89S51 to control the speed of 12V fan according to the surrounding temperature. In this project we use the concept of PWM (pulse width modulation) to increase or decrease the speed of fan. We also interface 2*16 characters LCD which shows the outside temperature through the temperature sensor. Followings are…
