LCD or LED Volt & Ampere meter using ATtiny26 - [Link] [Google Translation]
This is a simple use of internal ADC of AVR atmega8. Voltage is measured directly with help of resistor divider and amperes is calculated based on the voltage drop in a low resistance power resistor.

Jeri Ellsworth has produced the first two in a series of A to Z electronics videos, sponsored by Adafruit. Here are A is for Ampere and B is for Battery.
Ampere is a unit of measurement for current and was named after André-Marie Ampère. [via]

PIC Voltmeter Amperemeter can measure voltage 0-70V or 0-500V with 100mV resolution and current consumption 0-10A or more with 10mA resolution. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. The meter uses PIC16F876A microcontroller with built-in ADC (Analog to Digital Converter) and 16×2 green backlighted LCD display. With slight modification it is possible to measure higher voltage and current.
