Seeking experienced engineer familiar with Arduino to add some features to my Particle Photon firmware.
Basic functions already implemented include: reading & calibrating sensors, logging data to MicroSD, publishing data to Parse.
Functions still needed: 24-hour timer, countdown timer, & sensor reading-based logic as well as manual override for 4 relays, all user-controlled from iOS app. Control settings & data logging will need to persist throughout various system states, & be updated on re-connection.
