How to interface 16×2 LCD module with Arduino

by

An LCD (Liquid Crystal Display) module with a 16×2 configuration is commonly employed in electronics projects, especially those involving microcontroller-based systems like the Arduino. The “16×2” specification denotes its dimensions: it features 16 characters per line across 2 lines, resulting in a total display width of 32 characters. Each character typically consists of a 5×8 … Read more

Distance Measurement using Ultrasonic Sensor (HC-SR04) and Arduino

by

The HC-SR04 module is a specific ultrasonic sensor module commonly used for distance measurement. It comprises an ultrasonic transmitter-receiver pair and control circuitry, all integrated into a small board. The HC-SR04 operates by sending out a burst of ultrasonic sound waves and then measuring the time it takes to bounce off an object and return … Read more
