How to make an Arduino Voltmeter As you may well know, Arduino’s analog inputs can be used to measure DC voltage between 0 and 5V (when using the standard 5V analog reference voltage) and this range ...

Voltmeters aren’t terribly expensive, but it’s always more fun to build your own devices. YouTube DIYer Educ8s builds a cheap voltmeter for less than $10 using an Arduino and a voltage sensor ...

But what if the Arduino Uno was released in 1980? You’d probably get something like [ElectroBoy]’s 8051-based Arduino Uno. Close-up shot of the 87C752, an 8051 with EPROM.

Also keep an eye on the self-consumption of the DC voltmeter used with the setup (for me, it’s around 20 mA). It’s almost been six weeks since I’ve looked at an Arduino-based DC DVM concept, but ...

The voltmeter has a fixed measurement range from 0 to 100 VDC, the only switches on the board are for powering it on and a hold button, which freezes the value currently being shown in the three ...

But a company called ArcBotics has created an Arduino-based robot called "Sparki" that can be used—and programmed—by anyone. You don't have to assemble it yourself; ...

Arduino enthusiasts and makers looking for a project to keep them busy this weekend may be interested in a new Arduino ... including the voltmeter he based this off. Watch this video on YouTube ...

That's why we were really excited (and a little scared) to come across BakerTweet, a WiFi-enabled, Arduino-based prototype that one mounts on the wall of their bakery.

London-based roboticist Evangelos Georgiou wants to offer an open-source platform for helping Arduino hobbyists take their projects mobile, thanks to a remote controlled robot called the RK-1 that ...

Of all the Arduino projects we've seen 'round here, this is certainly one of them! Using nothing but a Graphics LCD, an Arduino, and a WebSocket server he wrote using Python / Tornado, ...

MintDuino: Building an Arduino-compatible Breadboard Microcontroller: Perfect for learning or teaching the fundamentals of how microcontrollers work, this hands-on book shows you how to build a ...

The Arduino uses latitude and longitude to help decide when to click on the lights, so it's incredibly accurate. Otherwise, the build just includes an on/off switch, a Tiny RTC, a time adjustment ...
