How can I make an ammeter for ~5V DC up to 3A? I want to connect this ammeter to a microcontroller. Answered
I want to connect this ammeter to a microcontroller ADC and display it on 7-segment displays. I guess a 10W resistor ~0.1ohms or something will be involved. I can obtain them easily. I want to make an inline USB ammeter. I am experienced with PICAXE microcontrollers and surface-mount.
