And now make some music with it!
What's the faint clicking sound when you start te program? Are the relays jumping to the 'off' position?

[@PeetSneekes]

Victor van Dijk Jip, that's the resetting of all relays. :-)

Does it make the light flicker? Might be a problem depending on the devices you connect.
