In this video you can learn and design a simple delay timer circuit using very ordinary components like transistor, resistor and capacitor. These circuits will produce delay OFF time intervals at the output for a predetermined period, from a few seconds to many minutes. This design are fully adjustable when changing the Capacitor or Resistor value. (i.e.) T=R*C
