Simple Computer A/D Uses a Serial Port

Here is an inexpensive way to get slow-moving analog data directly into a spreadsheet on your computer! A simple circuit connects to a serial port and a short Qbasic program gathers and saves 12 bit data to a file. A spreadsheet automatically retrieves the file and displays the data in real time.This simple interface can be built right into your project, turning it into a computer peripheral device.
