Summary of Multimeter with Atmel using Atmega8-16pu microcontroller
This article describes a DIY multimeter project utilizing the Atmega8-16pu microcontroller. The device functions as a voltmeter with automatic range switching for 0.00–9.99V and 10.0–30.0V DC inputs, a frequency counter capable of measuring up to 7999 MHz theoretically, and a logic tester that identifies Low, High, or open line states.
Parts used in the Atmega8 Multimeter:
- Atmega8-16pu microcontroller
- Voltmeter circuitry (positive DC)
- Frequency counter module
- Logic tester circuit
Atmega8 Multimeter
“Multimeter” was the only title to einfiel to me first. Voltmeter (only positive DC) 0.00 – 9.99 volts and 10.0 – 30.0 volts with automatic range switching.
Frequency counter 0 .. 7999 MHz (Theoretische) with automatic Switching time Basis
Logic tester L – prohibited area – H (actually also open line)
