Presented is a simple temperature alarm which uses a PIC16C84 microcontroller and a 2-line LCD display. The alarm displays current temperature in both Celsius and Fahrenheit degrees and features a 3-key keypad which allows the user to set independent high and low temperature alarm points. The alarm also records the minimum and maximum temperatures encountered.

This is a simple PIC16F84A programmer using only a few components. It programs pic16f84a and pic16c84 and connects to RS232.

Kees Krijnen writes:The Microchip PIC16C84 was one of the first serial in-system programmable microcontroller. I saw PIC serial programmers published in Electronic magazines in 1993. Today, many PIC programmer circuits Рfor serial and parallel PC ports Рare published on the Internet.Despite its somewhat unusual design Рlike the 128 byte page RAM/Register direct/indirect memory mapping Рit is a popular microcontroller, easily available and programmable now as flash microcontroller 16F84. The developer environment MPLAB from Microchip is free of charge and many application examples are available. [via]
