Codevoorbeeld: Vermogensregeling voor sensoren en LED

De Mercury altimeter heeft sensoren en Neopixel LED's die standaard uitgeschakeld zijn. Deze functie bestaat zodat items in diepe of lichte slaapstand naar behoefte kunnen worden uitgeschakeld om stroom te besparen en met maximale efficiëntie te werken. Dit betekent echter wel dat u de stroom moet inschakelen voordat u items gebruikt.
