Pocket-Sized Multiduino Does It All

How many times have you wished for a pocket-sized multimeter? How about a mini microcontroller-based testing rig? Have you ever dared to dream of a device that does both?

Multiduino turns an Arduino Nano into a Swiss Army knife of portable hacking. It can function as an analog multimeter to measure resistance, voltage drop, and continuity. It can also produce PWM signals, read from sensors, do basic calculator functions, and display the health of its rechargeable battery pack.

Stick a 10kΩ pot in the left-side header and you can play a space shooter game, or make line drawings by twisting the knob like an Etch-A-Sketch. Be sure to check out the detailed walk-through after the break, and a bonus video that shows off Multiduino’s newest functions including temperature sensing, a monophonic music player for sweet chiptunes, and a virtual keyboard for scrolling text on the OLED screen. [Danko] has a few of these for sale in his eBay store. They come assembled, and he ships worldwide. The code for every existing function is available on his site.

More of a maximalist? Then check out this Micro-ATX Arduino.

Thanks for the tip, [Rahul].

    1. I suppose that depends on how you look at it. Kristina spelled it the way it was probably MEANT to be spelled, whereas the site/video is calling it “Multidurino” which doesn’t really make any sense. It’s Arduino, not Ardurino. Judging by the spelling and grammar on the site, I’m guessing the project name was a screw up to begin with.

        1. Yes, but it’s obviously a mistake. The guy in the video is saying “Multiduino”, but the text is “Multidruino”.

          If you look at the comments in the YouTube video, somebody even asks him why it is spelled that way and he says “I don’t know, I didn’t even notice”.

          Which should give you an idea of how seriously he’s taking the project, but that’s another story…

  1. I’m not sure I have a good feeling about this one. It looks like a thinly veiled attempt for this guy to sell his little janky boards on eBay. I don’t see an schematics or board files to actually make your own, and the video seems to conveniently neglect to mention that all those functions are separate Sketches that you need to flash.

  2. If you’re going to do an Arduino this size why not use one of the bazillion ESP boards so you have wifi, which would make it about a thousand times more useful…
