Digital Thermometer Circuit using Arduino and IC LM35
The goal of this project is to construct a digital thermometer with an IC LM35 temperature sensor and an Arduino microcontroller. The Arduino translates the voltage that the IC LM35 outputs in relation to temperature into a readable value. For a very long time, people have used thermometers to measure temperature. For ease of visualization, […]
Interfacing a 7-Segment Display Circuit with Arduino UNO
A 7-segment display is a typical electrical component that displays numerical digits. It is made up of seven LEDs grouped in a certain way to represent numerals and basic alphabets. Interfacing it with an Arduino allows us to programmatically control the displayed digits. This tutorial will walk you through the steps of attaching a 7-segment […]
DC Motor Speed Controller Circuit using Arduino
This project shows how to regulate the speed of a DC motor with an Arduino microcontroller, a MOSFET transistor, and a potentiometer. The Arduino creates a Pulse Width Modulation PWM signal that controls the MOSFETs gate. The MOSFET acts as a switch, regulating the voltage provided to the motor and so managing its speed. The […]
Arduino 2-Step Programmable Timer Circuit with Independent Output Delay Adjustment
An Arduino microcontroller is used in this project to create a versatile timer. Unlike a traditional two step timer with separate outputs, this circuit focuses on a single output that cycles through two distinct states, each of which has an adjustable delay to allow for flexibility in controlling different applications. Circuit Working: Parts List: Component […]
