# A Microcomputer-Controlled Temperature Controller

A cheap but versatile microcomputer-controlled temperature controller costing less than $100 is described. The system is built around a Timex/Sinclair 1000/ZX81 microcomputer. This is a truly digital system employing the proportional-integral-derivative feedback-control algorithm, thus making the system capable of producing any required temperature profile at a low cost.
