Arduino Auto Power off. Make Arduino power off itself!
https://www.electronics-lab.com/arduino-auto-power-off-make-arduino-power-off-itself/
In this video educ8s.tv show us how to make Arduino power off itself with the help of a simple circuit! If you have watched some of my previous videos you will know that I like my projects to have minimal power consumption so that we can use them with batteries for a long period of […]
Easy Arduino Menus for Rotary Encoders
https://www.electronics-lab.com/easy-arduino-menus-for-rotary-encoders/
SimonM83 has posted a new tutorial on how to implement an Arduino menu using a rotary encoder. The tutorial goes through the hardware setup and sample code is provided. Rotary encoders with centre-push buttons are cool input hardware for projects, especially if you want to be able to scroll through menus and select options. Hopefully […]
Teensy 3.2 VS Arduino Due and Arduino Mega. Which one is faster?
https://www.electronics-lab.com/teensy-3-2-vs-arduino-due-and-arduino-mega-which-one-is-faster/
our friends at educ8s.tv wanted to test out how fast the Teensy 3.2 is, so he build the project above. I wanted to find out if Teensy 3.2, despite its small size, is faster than the Arduino Due, the fastest Arduino board available today. So I build a simple project where both boards run the […]

A simple signal strength indicator for the ESP8266 and 128 x 32 OLED Display This is a simple Arduino IDE sketch that displays the RSSI, BSSID and signal “bars” of a given SSID WiFi Signal strength indicator using ESP8266 – [Link]
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 […]
