Hi iam working to make digital speedometer to my car
the old speedo is down i want to make now digital one
i use PIC16F84A i got readings from digital pulse wire (frequency) i want to transform it to pic then to 7segment the problem is how to read that pulses i read that you must use a regular counter and others say you must use gates !
guys iam a programmer not electronics engineer and iam new to pics
please help me i want to understand how to read frequency to pic and do some calculations from Hz to Km/h and i will provide the readings :

please help me i want to understand how to read frequency to pic and do some calculations from Hz to Km/h and i will provide the readings :
Code:
KM/h > hz
40 > 2000
.

.
80 > 6000
90 > 7000
100 > 8000
110 > 9000
120 > 10000
