In the below code the function thermistor is reading the value from the analog pin of the Arduino, To give the supply to the Arduino you can power it via USB to your laptop or connecting 12v adapter.

This project was put together after learning the basics of Arduino and experimenting with circuitry. Other circuits I built included ultrasonic sensors, motors, buzzers, buttons, LEDs, and more.

Realized using the simple MCP9700A linear thermistor connected to pin A1 of the Arduino Uno (R3). The system converts the output voltage from MCP9700A to a temperature value and displays it on a 16x2 ...

This Arduino code controls a 16x2 LCD screen to display a counter that increases every second: #include <Adafruit_LiquidCrystal.h> - Imports the Adafruit LCD library to communicate with the LCD ...
