hi all, thank you so much for your replies, granted I'm a total newbie, so apologies, for not knowing the rules etc. bit of a fix, that's all, the original version that was very kindly reposted correctly blh64 thnanks, doesn't seem to simply turn on off the relay, but it has timers involved, count down etc. I really just need this to either be on or off when cycling, yes a school project of sort I suppose, I'm learning eh! thanks all again
