How to control LM2596 buck-converter with microcontroller


https://www.electronics-lab.com/how-to-control-lm2596-buck-converter-with-microcontroller/

by hugatry @ hackvlog.com: Every now and then someone asks on different forums if there is an way to control cheap LM2596 modules with an Arduino or another microcontroller. I decided to demonstrate one solution that might be basic electronics for some, but still many don’t know about. Those buck converters will change the output voltage […]

DIY Digital Compass


https://www.electronics-lab.com/diy-digital-compass/

by DaAwesomeP @ instructables.com: I’m astounded that some cars don’t have a digital compass always visible. You either have to launch the navigation app each time which may even disappear when you adjust the radio. In this project, you’ll create a digital compass that can be powered by by the cigarette lighter or another source (batteries […]

Arduino Radar Tutorial: Fading an LED With My Breath


https://www.electronics-lab.com/arduino-radar-tutorial-fading-an-led-with-my-breath/

by build-electronic-circuits.com: I built this Arduino radar project, where I control the brightness of an LED with my breath. In this tutorial, I will show you exactly how to do it. It was an experiment to get the XeThru radar to work with Arduino. I plan to expand on this later, and build more useful applications. […]

Arduino dust sensor


https://www.electronics-lab.com/arduino-dust-sensor/

Shadowandy’s Arduino-based Dust Sensor project: Put together a dust sensor using Arduino Mega 2560, Shinyei PPD42NS dust sensor and LCD shield. The codes and wiring instructions for Arduino Mega 2560 and Shinyei PPD42NS is as follow. However, I did include Serial output so you can view the sampling results using Arduino IDE’s Serial Monitor (9600 […]

Arduino-based “Analog” slow cooker controller


https://www.electronics-lab.com/arduino-based-analog-slow-cooker-controller/

Dan Ternes blogged about his Arduino-based controller for analog slow cookers: With the AC power control figured out, I considered the User Interface. I opted for something simple. The Adafruit RGB LCD Shield would work well as it had both a display and buttons built in. Sure, I could have beat this project about the […]

by benhur.goncalves @ instructables.com: Hey folks! After making an Arduino smartwatch just last week, I received many complaints,or tips, to use a RTC (real-time clock) module. That’s because the Arduino timer is not very precise, it can lose a couple a minutes along a full work day. Luckly, I had one of those modules at my […]

This is a no frills DIY Analyzer intended for frequencies ranging from 1.6 to 30 Mhz. This simple Antenna Analyzer could be a nice project for anyone just getting started in setting up a station on the HF bands. Arduino DDS AD9850 Antenna Analyzer – [Link]

Arduino Watch With Altitude, Temperature, Compass And Pedometer


https://www.electronics-lab.com/arduino-watch-with-altitude-temperature-compass-and-pedometer/

by benhur.goncalves @ instructables.com: Hi folks! Last few days I’ve been obsessed with the idea to make my own watch from arduino parts, but something cool I could use and say I did it myself. So I found out there was a sensor board (commonly named GY-87) which had three sensors on it: HMC5883L (compass), BMP085 […]
