I am working on a project that will take an analog signal as input(using a sensor that changes resistance when exposed to a gas). I am going to use an arduino to monitor the voltage, convert it and send it to a Max7221 led decoder to drive 5 seven segment display digits. I have zero experience with an arduino though. I've done visual basic and java. Im wondering if this has been done and is common/easy, or if im gonna have to figure this all out. Another thing is I believe the input is 10 bits, and the max7221 takes 8bit bcd as input. Any advice would be appreciated


Any advice would be appreciated

See that search button up there? Way at the top. Right in the middle. Put it to use.

You are not, by a long shot, the first person who has wanted/needed to do this.

That's my advice, and worth every penny you paid. :D

Jeez...I was on my phone in the car...im so used to other forums where the search button is a button right next to home, profile etc..I didn't see it up top. Then you said see the search button....I was like no haha..... I've found a couple things now...hopefully I can get this done. Sorry for the typical n00b behavior
