How To Make Automatic Fan On Off And Temperature Control Circuit Youtube How to make diy automatic fan on & off temperature sensor circuit.today i will show you how to make a cooling fan automatic on and off temperature sensor cir. 3. lm35 temperature sensor. about relay: relay is a switching device. like we put the switch in a normal circuit and do it on and off similarly relay is a device when receives command makes switch on or off. in this tutorial when the temperature exceeds 26 degree celsius then arduino pin 1 is high i.e. the vin pin of the relay will get 5 volts. Connect v0 pin to the center pin of 10k potentiometer. connect other two pins of potentiometer to the 5v and the ground. connect rs pin to the pin 2 of arduino. connect r w pin to ground of arduino. this will put the lcd in read mode. connect e (enable) pin to the pin 3 of arduino. Circuit playground express is the newest and best circuit playground board, with support for circuitpython, makecode, and arduino. it has a powerful processor, 10 neopixels, mini speaker, infrared receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, ir proximity, temperature, light, motion.
