Problem Statement

Design a test system to operate and monitor

JCI Homelink Trainable Garage Door Opener (GDO) Transmitters under the conditions that would be characteristic of a product installed in a modern automobile. The test system should be capable of monitoring the operation of the system while exposed to a number of conditioned variables. If a discrepancy is found, the conditions at the time the error occurred should be automatically logged to a spreadsheet file.
