Hi Everyone, I am out of ideas here. I am looking for a way to dump the air in my motorcycle air shocks when I turn off the ignition. This will be accomplished by energizing an air solenoid. That is why I need to power it for 15 seconds, then turn it off. I thought I could do it with a simple delay circuit with discrete components, but I can't figure out how. I know it would be simple to do with an Arduino, but I need to make it as small as possible, and I lack the programing skills necessary. Thanks for any ideas, adown
