is that program also posible in python? because i cant figure it out

i think it's imposible for me to program a RPM counter for now.

i like the raspberry pi, but i'm not able to understand it in 1 week time.
i tried to make a simple button that light's up a single led, but it failed.

i thought it would be easier to make i little program.

i got a question?

on the link they show me timers that can stop and restart OK

but how can i count pulses? and how can i bring does 2 things in one working program?

that link looks promesing

i wil try to make a counter and show it to all of you. maybe i need to change it

but what for cammands do i need to type?

while True:

?? i don't know the commands to count in one loop per second

option one wil work fine.
how would my program look like?



import RPi.GPIO as gpio

gpio.setmode(gpio.BCM)

#i need only one input

gpio.setup(17, gpio.IN)

while True:

gpio.counter(17)*60???????????????????????????????????
????????????????????????????????????

JRV,

you use c++ but i don't have that on my raspberry

so i think it won't work because of the lange diffrence

Tarcas, at the moment am i capabele to do some little programing. i tryed to make this program : https://www.youtube.com/watch?v=ZpkI2JGdtAA i would use that pushbuton as my "pulse" to try it out. i understand how the GPIO works, but to count my pulses and recalculate them to rpm is a mystery for me.

i don't have the brains for it.

i"m making this air engine: https://www.youtube.com/watch?v=vcaFWg-FvbQ

i think it goes at least 400 rpm

I HOPE SOMEONE CAN GIVE ME AN SOLUTION: IS IT POSIBLE TO SEND AN LITLE PROGRAM AND A WAY TO DO THE SECUIRD BORD FOR THE SENCOR?

THAT WOULD BE GREAT

i tought about a infra-red censor that detects my flywheel of my compresed air engine. so if the raspberry detect pulses and count them on timeperiods. it would be posible to calculate the speed in km/h thats my theorie what is yours. i can buy stuf like that in local stores. thanx for helping me an...

hi,

i'm a student, i builde a radiale air engine as project. but i have a raspberry pi, so i want to use the raspberry as rpm counter.
