// Relay won't turn on - Check input voltage, should be 5V
// - Check if R4 on the Board is installed, if yes, remove it
//
// Relay clicking during start - Put a SMD capacitor at the place where R4 should be. Reason: the used chip pulls all Pins high during startup. The capacitor will catch the peak.
