Experiencing Arduino SPI (interrupt)
A Microcontroller uses many different protocols to communicate with various sensors and peripherals. There are many protocols for wireless and wired communication. Most of the things that...
Simple UART by Arduino
ExaMPLE #1
Remote LED blinking
Here a simply circuit consisting of two Arduinos with the following connections:
MAX72-21/19 Arduino Library
These two chips provide an easy way to control either an array of 64 Led's or up to eight digits made of 7-segment displays with a minimum...
Serial Communication Tutorial
When you upload any sketch to the Arduino board, stare at the board as the codes get uploaded bit by bit, you will see two SMD LEDs on...
Complete Arduino Serial
Here we look at using serial communication on the Arduino. Serial
UART is one of the various ways an Arduino can communicate with other
devices. This includes a host...
USART in Arduino
Introduction
USART
(Universal Serial Asynchronous Receiver Transmitter) is a serial
communication protocol used to transmit/receive data serially at a
specific baud rate.
Microphone Sound Sensor
The microphone sound sensor, as the name says, detects sound. It gives a measurement of how loud a sound is.

Ultrasonic vs Infrared Sensors
Your choice of a sensor in your
application can be challenging for any project. The performance of your
system depends greatly on the reliability of your sensor and other...
Ultrasonic sensor
Ultrasonic sensing is one of the best ways to sense proximity and detect levels with high reliability.
It emits an ultrasound at 40 000...
Protected: WS2812B Addressable RGB LEDs
If you have made some sort of LED related project, then you probably might have used discrete LEDs (either through hole or SMD). These LEDs may be single color...
