Modify existing open source Arduino Sketch for Adafruit's data logger to log 5 analogue inputs and 2 digital inputs.
The analogue inputs will be 4ma-20ma (5V across 249omh shunt resistor) from 0-345Bar pressure transducers. The digital inputs will be from momentary push buttons and must have de-bouncing in the sketch.
The pressure must be logged and displayed real time on an LCD in BAR and PSI units. Each analogue input shall display CURRENT, MIN and MAX values logged in the past [url removed, login to view] is no need to recall previously logged data on the LCD.
You will need to specify a cost effective LCD screen to use with this project.
Additionally, a digital input from a toggle switch shall energize a relay to power the transducer circuit.
Hardware is Arduino Duo, Adafruit's data logger shield, automation direct prosense pressure transducers and the LCD display of your choosing.
