Abstract
This paper describes the use of the open source hardware platform, denominated Arduino, for controlling solenoid valves for solutions handling in flow analysis systems. System assessment was carried out by spectrophotometric determination of iron (II) in natural water. The sampling rate was estimated as 45 determinations per hour and the coefficient of variation was lower than 3%. Per determination, 208 µg of 1-10-phenanthroline and ascorbic acid were consumed, generating 1.3 mL of waste. Arduino proved a reliable microcontroller with low cost and simple interfacing, allowing USB communication for solenoid device switching in flow systems.
