Sparkfun Frequency Counter Kit

Postby JohnCrow » Sun Dec 11, 2016 5:02 pm

I've just assembled a nice little project, a simple frequency counter based on an ATMEGA 328P device.

Its programmed using an Arduino Sketch. (The device comes pre-programmed).
Source code can be downloaded from the Sparkfun website, and should be possible to rewrite in flowcode.

Specified Maximum Frequency 6MHz. (50% Duty Cycle)
Although the project does not claim to be highly accurate, for the cost of just under £30.00 including carriage its quite good value.

Instead if soldering the display to the main board, I used a SIL header and socket. This means it will be easier to repair if any components fail.
Also I used a TP socket for the ATMega device.
