Arduino- TM35 Controlling a DC 12v FAN With Temperature Sensor

Hello world! Today i made a simple project with a LM35 Temperature Sensor and a LCD1602 Screen to control a 12v DC Fan with a arduino and a Relay. Check out the next step for the Schematic, Code & Parts list.

Simply wire it up like the schematic make sure you have the library LiquidCrystal.h installed, And upload the code.

Parts list:

1. Arduino uno, i used the RobotDyn uno. (Has 8 analog pins)
2. LCD 1602.
3. LM35 Temperature sensor.
4. KY-019 Relay module
5. Potentiometer
6. 12V DC FAN (From a old computer will do.)
7. Jumper wire set MM/FF/MF

Good luck!
