yeah i m using smart pi as an external hardware. it will be sending useful data to rpi. What i want to ask is how can i transfrom that to sub inputs i.e voltage, current, frequency.
I am making a project in which i will be taking input from raspberry pi then transfroming single input into string of differnet inputs like voltage ,current, frequency. so how can i transform input that i will be taking from single pin of raspberrypi to voltage,current and frequency
