[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

Makers, hobbyists and electronic enthusiasts looking for a project to keep them busy this weekend may be interested in this awesome Arduino temperature and humidity sensor which has been created by ...

This project illustrates the control of NPN power transistor using PIC16F876A to further drive DC brushless fans, LEDs, and buzzers when the specified temperature was detected. An LCD screen is used ...
