Simple and Inexpensive 8-Bit Analog to Digital Converter for the PCs Parallel Port

Abstract
A simple and inexpensive 8-bit analog to digital (ADC) converter based on the ADC0804 integrated circuit, for replacing stripchart recorders by measuring analog voltages through the Centronics port (printer or parallel output) of an IBM-compatible personal computer, is proposed. A QuickBasicTM program for driving the circuit and a single-supply input amplifier are also described. All the circuits require low-cost, easily available commercial components and can be supplied by a 9 volt battery, making them portable and well suited for educational purpose.
