Arduino 433Mhz RF Wireless Data Transfer
https://www.electronics-lab.com/arduino-433mhz-rf-wireless-data-transfer/
Here is a tutorial on how to use 433MHz RF modules to send data from an Arduino to another. The example code transmits a message to the serial port of receiver. The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver. The […]
Arduino Voltmeter With OLED Display
https://www.electronics-lab.com/arduino-voltmeter-oled-display/
Konstantin Dimitrov has published an Arduino tutorial on how to make an voltmeter using SH1106 OLED display: I’m going to show you how to make a voltmeter with Arduino UNO, an OLED display, 2 resistors and 9 jumpers for less than 5 minutes. With it you will be able to measure voltage from 0 to 30V […]
ECG Arduino Shield
https://www.electronics-lab.com/ecg-shield-arduino/
This project is an Arduino shield able to measure ECG and respiration. The shield is equipped with a LCD display to show measured signal in real time. It’s based on ADS1292R ECG Front End from TI. Recently i made shield for arduino which can measure ECG, respiration, eventually after some changes in PCB and code, EEG and EMG. […]
Programming an ATtiny with Arduino board
https://www.electronics-lab.com/programming-attiny-arduino-board/
This detailed tutorial shows how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. The ATtiny45 or 85 is a great option for running simple Arduino programs: it’s small, cheap and relatively easy to use. It does, however, have some limitations relative to the ATmega328P on an Arduino Uno. There are […]
Arduino Remote Control Tutorial

Øyvind Nydal Dahl show us how to use an IR remote control with Arduino. For this purpose he connects a TSOP312 and an IR LED to Arduino and goes in detail on the sketches. In this tutorial I am going to show you exactly how to make an Arduino remote control. You can use this […]
Wireless communication between two Arduinos using inexpensive RF modules
https://www.electronics-lab.com/wireless-communication-between-two-arduinos-using-inexpensive-rf-modules/
Raj from Embedded Lab has posted a new article exploring an easy wireless communication setup between two Arduinos using low-cost ASK RF transmitter and receiver modules. He used a 433MHz Tx/Rx pair with two Arduino boards to illustrate how to construct a low-range wireless temperature and humidity monitor. Wireless communication between two Arduinos using inexpensive […]
AC PWM dimmer for Arduino
https://www.electronics-lab.com/ac-pwm-dimmer-for-arduino/
diy_bloke @ instructables.com has designed an AC PWM dimmer for Arduino: Over 3 years ago, I published a simpel TRIAC AC dimmer for the arduino. That proved to be a very popular design. Yet in spite of the simplicity of the circuit the software needed was a bit complicated as it needed to keep track of […]
$2 Arduino – ATMEGA328 as a stand-alone
https://www.electronics-lab.com/2-arduino-atmega328-as-a-stand-alone/
In this tutorial you will learn how to use ATMEGA328 microcontroller as standalone Arduino. This way you can minify your next arduino project. They cost only 2 bucks, can do the same as your Arduino and make your projects extremely small. We will cover the pin layout, how to make it ready for the Arduino […]
Arduino controlled Triac light dimmer
https://www.electronics-lab.com/arduino-controlled-light-dimmer/
diy_bloke @ instructables.com has build an arduino controlled triac light dimmer and describes the circuit and software used to achieve that. It becomes a bit more tricky if one wants to dim a mains AC lamp with an arduino: just limiting the current through e.g. a transistor is not really possible due to the large […]
Arduino Inline Assembly Tutorial
https://www.electronics-lab.com/arduino-inline-assembly-tutorial/
ucexperiment.wordpress.com has published a series of tutorials on how to use assembly language on Arduino. This can be pretty helpful if you want to do some advantaged coding on Arduino. An inline assembly statement is a string which specifies assembler code. The string can contain any instructions recognized by the assembler, including directives (we will […]
