How to Build a Temperature-Based LED Bar with TMP36 and Arduino
How to Build a Temperature-Based LED Bar with TMP36 and Arduino In this project, we’ll use a TMP36 temperature sensor and an Arduino to light up a row of LEDs based on the ambient temperature. As the temperature increases, more…
How to Control a Servo Motor Using a Potentiometer with Arduino
Have you ever wanted to move something smoothly with your hand and see it come to life using a servo motor? Whether you’re building a robotic arm, a remote-controlled car, or just exploring electronics, learning how to control a servo…
Using IR Remote Controls with Arduino
Infrared (IR) remote controls are everywhere these days — you’ve probably used them to control your TV, speaker system, air conditioner, fan, or even to switch a light on and off. But here’s the cool part: you can also use…
Digital and Analog Signals: An In-depth Technical Guide
Signals form the basis of communication in electronic systems, allowing devices to transmit and process information. Broadly, signals can be classified into two fundamental types: analog signals and digital signals. In this comprehensive guide, we’ll dive deep into the specifics,…
Understanding Pulse Width Modulation (PWM)
Digital signals are binary — they can only be either 0 or 1. Analog signals, however, have a continuous range of values and are not limited to just two states. Both types of signals are found in electronic systems, but…
