Arduino-based Point-of-sales system I made a point-of-sales system using Arduino, a receipt printer, a 20x4 LCD and a keyboard on October 13, 2012. I thought it would be a good exercise for me because I really wanted a reason to use the Adafruit receipt printer and I would have an example of an embedded systems project that was complicated enough to require a state machine. I've documented all the hardware and software at: http://speedysignals.wordpress.com/2012/11/22/arduino-based-point-of-sales-system/ Dependencies (libraries used) ------------ Adafruit Thermal Printer Library Adafruit DS1307 Library LiquidCrystal Library PS2 Keyboard Library MemoryFree Library Streaming Arduino 1.0 Authors ------- Andrew Ong
