At the start condition all pin 15 are connected to the ground, so R0 is energized. A 555multivibrator sendsthe clock signalto IC1, which activates the outputs from R0 to R8. This simple circuit can be utilized to drive a monostable relay through a single button switch. At the start condition the relay does not work. When I press the button (P) T1 is energized through R1 and R2, and the capacitor charges. The coil is jumped by
