LightKeeper

Dit is mijn eerste projectje waar ik een 'PCB' maak en transistors gebruik.

In de code staat een hele regeling waarmee de lamp feller of dimmer wordt door een vergelijking te maken met de gemeten lichtsterkte en de gewenste lichtsterkte.
Indien het verschil groot is stelt de lamp ook sneller bij dan wanneer het verschil klein is.
