Arduinotes is a system to take notes in a quick and reliable manner, based on a standard keyboard like a writing system (for me is the only possible solution if you are looking for comfort and fastness), and based on a EEPROM memory like a storage system. It is a system based on the Arduino microcontroller. There is a lot of people making interesting things with Arduino. In a previous post I showed how to build a temperature sensor based on Arduino.
This project is a little bit an academic project (somebody will argue about the utility of a writing system without a screen). But, if I were a journalist, I would take with me my Arduinotes, I would search for the best keyboard (a comfortable one, with strong key pressing, the smallest one and, if possible, a folding one), I would go to the press conference, and I would dazzle my collegues with my kit. If I were a pathfinder crossing the Sahara, I would put in my bag my Arduinotes to write every night my diary with the moonlight.
Arduinotes is reliable and functional because uses a standard computers keyboard, cheap because is base on Arduino and basic electronic components, portable because is pocket-size and weighs just, and autonomous because has a little battery consumption.
Besides hardware, software has been developed. First of all we use two Arduino libraries: the EEPROM’s library, and the keyboard PS2 library (needed to adapt); the source code developed, together with the libraries, represents the Arduinotes firmware, i.e. the software that we upload inside the microcontroller; and finally, a C language script that reads the serial port and saves to a file all the content of the EEPROM memory. Arduinotes uses an EEPROM memory (we are using a 64K memory, but could be bigger), and we divide the memory in 4 pages, so we can write in 4 different documents. Arduinotes has 4 modes: writing, erasing, saving and reading.
