Pre-Alpha Code

If you just want to hook up a MAF sensor to an Arduino with a basic display, you can follow the connection schema for the current basic pre-alpha version. This is just a very basic sketch but will get you up and running and will provide you a base from which to work. You will need to determine your MAF scaling (the cfm to volts relationship) to be able to display the results in CFM but that's something that you can get from your MAFs datasheet or measure and calculate with some simple tests. (Check the forums for help on how to do this)

You can download the pre-alpha code from the releases section:
