Hi..!!
I am doing a mini project to make a multimeter using PIC16F877A.I have an option to use arduino also.But i am confused.
How can i select the modes of a multimeter?
should i use a rotary switch or a keypad?
If i use rotary switch for mode selection(or range selection),then how the microcontroller will know which mode(or range) is selected?
please suggest me some circuit ideas...
