resistor R2. It receives a higher voltage when the brake is applied. Normally‚ when the brake is not applied‚ the output of IC2 remains high and the red LED (LED1) glows. The output of IC2 is fed to trigger pin 2 of the monostable through coupling capacitor C2. Resistor R1 is used for the input stability of IC2. IC1 and C1 provide a ripple-free regulated supply to the inverting input of IC2. IC3 is wired as a monostable to give pulse output of one second. Tim- ing elements

timers Introduction The NE555 chip which operates at 5v‚ utilizes two comparators for temperature stability. This chip is capable of producing oscillations. It is made up of 8 pins and its oscillation mode is controlled by two resistors and a capacitor. Each pin is set to perform a function. Pin 1 serves as ground. Pin 2 is the trigger - the input to the lower comparator which sets the latch that causes output to go high. Pin 3 serves as the output.
