Figure Lengend Snippet: Flowchart of the Arduino sketch used to measure the state of charge of alkaline batteries.

Article Snippet: We used Arduino UNO R3, Atmel MEGA328p SMD, and 11-bit oversampling to read the bits and different laboratory benchtop instruments to apply and read the voltage; specifically, we used two different DC power supplies (HP E3611A, TTi EX354D and three voltmeters (Agilent 34401A, HP 34401A, Philips PM2521) (respectively Hewlett-Packard Company, Loveland, CO, USA; Thurlby Thandar Instruments Ltd., Huntingdon, Cambridgeshire, UK; Agilent Technologies, Loveland, CO, USA; Philips Industrial & Electro-acoustic Systems Division, Eindhoven, The Netherlands).
