The PICAXE microcontroller system is a low cost, flash memory based microcontroller. The simplest PICAXE microcontroller IC the PICAXE-08. This is programmed using BASIC programming language. Once the programme has been written it is downloaded via a serial port on the PC direct to the picaxe circuit.

The PICAXE-08 has 8 legs, similar to many integrated circuits (ICs). However, the numbers of the output/input pins are not the same as the leg numbers. The table above shows the leg numbers and pin numbers and their functions. Great care must be taken when using the PICAXE-08 in a circuit as the leg numbers and pin numbers can be confused. The PICAXE-08 project board shown below has the PINS clearly labelled.

The PICAXE-08 Starter Pack is ideal for those wanting a programmable circuit with a limited number of inputs/outputs. The pack includes all the components and PCB needed to manufacture a programmable circuit with 5 inputs/outputs. The starter pack allows for experimentation as more components can be added.
It is also suitable for serious circuit building or as part of a larger circuit. Consequently it can be used in examination work in Electronics or Systems and Control.
