Hi there, firstly, let me just introduce myself to you guys, hi, I’m Rick and I’m coming from an Arduino background but have bought two of these Spark cores cos they look great.
However, they are a bit sparce on pins so I have had to rethink a control panel I originally designed for use on an Arduino Mega. I have a panel of 8 buttons which I want to connect using a resistor ladder to get an analog output. I have other stuff on the other pins so I need my 8 buttons to use as fewer pins as possible so the resistor ladder seems like a good solution.
If I use pin A0 as my reader for my button array, will it trigger the interrupt if my array only produces say .5v?
I have not received my cores yet so can’t test this out, it’s more of a feasibilty study currently, I see the core only outputs 3.3v so if anyone can tell me if this will work I’d greatly appretiate it.
Many thanks, Rick.
