#111983 - tachometer "which one is best" |
Hi
I am on a tachometer project. Pls suggest me the best one 1) Count number of pulses in one second and multiply into 60 2) Get the time between two pulses and calculate the frequency Details: i have planned to get signal from plug itself. (because it is a battery operated & have litte space) planned 300 rpm to 9999rpm is at89c52 enough for this project? any suggestions, design ideas & experience to share thanks Nandhu |
