What is the OhmDuino?

That´s a very good question!!

It is basically a keychain with some fancy LEDs, a capacitive touchsensor and a unique shape, that honors the great achievements of Georg Simon Ohm and is actually the logo of our university, the TH Nürnberg.

Why did you make it?

It describes our lifestyle full of making, building and DIY. It is the perfect starting point to get into electronics and programming. It is open source.

How can you program it?

Plug it into your USB-Port, load a sketch in the Arduino-Ide and let the fun begin!!

Are there examples on how to get started? We wrote several sketches to show the basic functions of the OhmDuino. For easy access, they are all available in the download section of our Hackaday-Page.

More information:

-> The OhmDuino features:

• 25 blue LEDs, which can be controlled individually via multplexing.

• two capacitive touch sensors, which can recognize fingers touching the PCB or the touchpads.

• an Atmega32U4 with it´s built in USB-connection.

• an ISP-/SPI-port for burning bootloaders or programms on the µC.

• an I2C-port and additional connection points for VCC and GND, to enable modifications and connectivity.

• a PPTC-fuse to protect your OhmDuino and your PC from damage.

-> The Hackaday-Page of OhmDuino contains:

• programming examples with explanations in the commentline.

• a manual (for now only in English) on how to set up the OhmDuino and how to do the first steps.

• all needed files, like the schematics or the board-files, to understand how the OhmDuino works.

-> Opensource in relation to the OhmDuino means that:

• you can download the eagle-files for free.

• reproduction and modification of the board is not limited in any way.

-> The OhmDuino is a good choice for you, if you:

• are openminded.

• want to experience something new.

• see the world in 0 and 1.

• don´t know what counting binary looks like.

• have a nerdy girlfriend or boyfriend.
