  • CAR TACHOMETER Circuit A 555 is configured as a monostable or one shot in this project. The period of the 555 is determined by the 47k and the capacitor from pin 6 to ground (100n). Time "T" = 1.1 RC or 1.1 X 50,000 X 0.1 X10 -6 = 0.0055 or 5.5 mS (milli-seconds). The 555 receives trigger pulses from the distributor points.
  • The Circuit. As stated, the circuity can be used to send calibrated pulses to a microcontroller-based tacho meter or similar circuit/device. The wiring of the hardware turned out to be deceptively simple. At the heart of the circuit is the OS25B10 transmissive optical sensor with phototransistor output (OC1).
