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.

Circuit that implements the function of a temperature sensor, with a thermistor (NTC). Specifically, we had to design the circuit to read the temperature from the sensor and display the temperature to ...

V-LED This is the VCC pin of the LED. Connect this pin to the 5V pin of the Arduino with a 150Ω Current Limiting Resistor. LED-GND This is the Ground Pin of the LED. Connect this pin to the Ground pin ...

The working principle of the water level sensor module is very similar to that of a Rain Sensor. The water level sensor has three pins, runs on 5V power, and gives out the data in analog format. The ...
