p_leriche @ instructables.com build a USB volume control which is simple, cheap and extensible. Check it out: I’m not the first person to publish an Instructable for a USB volume control, but I think this one is about as simple and cheap as it gets, and at the same time can be extended at minimal […]
How to control Arduino board using an Android phone
https://www.electronics-lab.com/control-arduino-board-using-android-phone/
Kerimil, user on Arduino Forum, submitted his project which focuses on establishing communication between an Arduino board and an android mobile using bluetooth: The idea is to gain access to hardware on Android devices (accelerometers, gyro, wifi connectivity, gps, GPRS, touchscreen, text to speech and speech to text) and/or use it to relay data to […]

In this article, you’ll learn how to build a system that can turn DC loads on and off using a mobile application. You’ll also learn how to perform this task via immediate actions or via timers set in advance for switching loads on and off. by Yahya Tawil You can implement this system in environments […]
Arduino IR remote and Software controller
https://www.electronics-lab.com/arduino-ir-remote-software-controller/
This is a DIY Infrared remote for speakers, replacing the original. Arduino Nano and controlled via a custom .NET application and placed in a laser cut enclosure. This one is an interesting one, it’s something we’ve been looking at for a while and figuring out how to solve it. We have sets of speakers and […]
Control ESP8266 over the internet
https://www.electronics-lab.com/control-esp8266-internet/
Here is a basic tutorial on how to control ESP8266 over the internet using two buttons on a browser window. The article goes through Arduino IDE configuration and example code is included. There are but a few things better than (succesfully) programming and using your Arduino. Surely one of those things is using your ESP8266 […]
