How to control LM2596 buck-converter with microcontroller

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 to make the feedback pin, connected to the output via a voltage divider, become 1.25V or so. If f ...

Gesture controlled car using Arduino

  Who doesn’t love playing with RC cars and Robots. Not only playing, engineers and enthusiasts like us love to build and experiment with these stuffs. Also its fair to say that RC’s and Robots have became more than just toys, they already have started to integrate into our life slowly. But to take this to another standard we have built a Gesture controlled car using the most powerful development board Ardu ...

Kristall 511 solder wire won´t dirt your PCB

ou, who are at production of electronic devices, know, how important is a choice of a suitable solder. A designer of a given device might not focus on a solder used at soldering of the first protoype, bu tin a production it will manifest itself – sooner or later. Not that some solder would be miraculous and otherone unusable, but each one is suitable for something else. Similarly lie in other segments, even ...

DIY Digital Compass (for your car)

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 make it handheld). You could buy one, but where's the fun in that? You'll use an awesome OLED screen (w ...

Arduino Radar Tutorial: Fading an LED With My Breath

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. And I will share with you how to connect the hardware, and how to create the Arduino code. Just to be clear: This is not a son ...

Analog Ultrasound Range Finder

When I started my career in control systems I was fascinated with the many different ways that machines could be interfaced to the environment they operated in. Limit switches (electrical and optical), encoders, resolvers, strain gauges, thermocouples... the control system engineer had a long list of sensors to choose from. And the list has grown even longer following successful innovations in micro machini ...
