Adjustable recycled timing controller using CD4001and CD4017

LCD timing controller is to use the electronic form of the "sub" signal, remove and divide by two circuits combined to form a multi-gear multi-level timing control function. It is controlled by controlling the switch can be composed of a single time on, off or auto-cycle mode. Control the time adjustable from l ~ 90min. Circuit as shown.
