It's assumed that you've read - and understood - the contents of the previous three sections. Here - we're going to add an automatic reset to Circuits 5 & 6. The act of switching the power off - will charge/recharge C1. So the timer is always ready to start - the moment Sw1 is moved to the "on" position.
