Hello All. I am a complete newbie to Arduino programming and hope someone can help. I have a project with the following requirements: 1. Detect first relay contact closure. 2. Start a countdown timer upon relay contact closure 3. When the countdown starts, activate a second relay 4. Continue to monitor state of first relay contacts. 4. At the end of the countdown, de-activate the second relay 5. If the first relay contacts open during the countdown, then stop countdown, reset timer and de-activate second relay 6. Go to step 1.
I would also like to be able to manually activate and deactivate first relay via the web/ethernet. Can anyone help with this? Thanks...Arniep
