ChrisTenone:
This is already made multimeter if I am correct, but I want to make my own.No, the link from BillHo is to a project to make a DMM shield from parts, not an already made multimeter.
And it looks like it may be a good one.
Yes I read the project I wasn't referring to BillHo but to someone posting current sensor link.
Project looks pretty decent.
I've ordered parts as said in the project for ammeter and voltmeter:
3x BSS123 PMOS
1x PTC 500mA
3x LM358
1x 5.6 V Zener diode
