Please help. How can I use an ici 555 as tacho. for motorcycle ??
I have found a few schematics that show how to use a 555 timer as a simple tachometer. They all state that the income are pulses that are collected at the low side of the ignition, the breaker points. My bike has an electronic ignition, if I used one of these 555 based tachs on my bike will it cause any harm to the ignition? The bike, a Harley Sportster, already has the wiring for a tach. routed from the ignition, but no tach. (I do believe).
