Improved Arduino Rotary Encoder Reading


https://www.electronics-lab.com/improved-arduino-rotary-encoder-reading/

Here is a nice tutorial on how to use rotary encoders with Arduino. Example code is included. I wanted to use a low cost rotary encoder as an input mechanism for one of my upcoming projects and was initially bewildered by the code options available to take readings from the rotary encoder and determine how […]

Testing DRAM Using an Arduino


https://www.electronics-lab.com/testing-dram-using-an-arduino/

Chris @ insentricity.com wanted to test a few dozen individual RAM chips so he decided to use Arduino to make his life a little bit easier. In the article he explains the interface with Arduino and gives the code on github. My first thought was to test the chips in the TL866CS, but it doesn’t support […]

Software Defined Radio (SDR) shield for Arduino


https://www.electronics-lab.com/software-defined-radio-sdr-shield-for-arduino/

by Clemens Valens @ elektormagazine.com The new SDR board was created by Burkhard Kainka, the designer who also did the first SDR project. The antenna preselector of the original board has been removed while the CY27EE16 programmable oscillator was replaced by the Si5351 from Silicon Labs. The Arduino board takes over the functions of the FT232R […]

How to measure mass of the Earth using Arduino


https://www.electronics-lab.com/how-to-measure-mass-of-the-earth-using-arduino/

victoryking @ instructables.com has posted a nice physics and arduino tutorial on how to measure the mass of earth. This is an indirect method to calculate the mass of earth by measuring acceleration due to gravity with the help of arduino. One fine day, I was weighing my self on a weighing scale. Suddenly a […]

Arduino – Processing Laser CNC Project


https://www.electronics-lab.com/arduino-processing-laser-cnc-project/

Neumi @ github.com has build an Arduino based CNC project and source files are provided. This is my scratch build Laser CNC Engraver and PCB Exposer. It uses a 150mW 405nm laser diode and two CD drive motors and mechanics. A Processing sketch calculates the position of the pixels and send them to an Arduino Mega, […]

Control a High Power 4W COB LED with Arduino Uno


https://www.electronics-lab.com/control-a-high-power-4w-cob-led-with-arduino-uno/

educ8s.tv has published a new Arduino Video tutorial: High Power LEDs are very popular and low cost nowadays so I thought it would be a good idea to learn how control them with Arduino. So, I built a simple project that simply turns on a 4W Cob LED when the button is pressed. When the […]

Controlling Arduino using your Voice


https://www.electronics-lab.com/controlling-arduino-by-voice/

bluehybrid @ instructables.com shows us how to use your voice to control a led light on Arduino. To achieve this he used the 1Sheeld Arduino shield. This Project is getting start to use arduino with 1Sheeld In this project we will turn an LED (ON) and turn it (OFF) by Voice We will say “Open” to turn […]

Hardware serial port monitor over WiFi


https://www.electronics-lab.com/hardware-serial-port-monitor-with-wifi/

This tutorial shows how to connect Arduino to the TX line (of a router, RPI) and display serial data on smartphone over WiFi. Arduino listens for serial port communication on its hardware serial port. Then it sends every received line of data trough software serial port to ESP8266. ESP8266 puts every received line of data […]

Arduino DS18B20 Thermometer on iOS or Android


https://www.electronics-lab.com/arduino-ds18b20-thermometer-on-ios-or-android/

maroelawerner @ instructables.com has a tutorial on how to display temperature data on an Android or iOS device using Arduino and Blynk app. In this Instructable I am going to attempt to show you how to put together a little project to use the Blynk app (optainable at http://www.blynk.cc/) to display the temperature remotely on a […]

Geiger–Müller counter that works with Arduino


https://www.electronics-lab.com/geiger-muller-counter-that-works-with-arduino/

Bob @ robertgawron.blogspot.com has posted a Geiger-Muller project that can be used with Arduino or any other microcontroller board. The Geiger–Müller counter is a relatively simple tool to measure ionizing radiation. To increase sensitivity, construction presented here contains three (instead of one as usually) soviet STS-5 lamps. This is important for measurements of natural sources of […]
