What is a Snap LED MC module?

The Snap LED MC module is a dual seven-segment LED display driven by a microcontroller and supporting electronic parts. The microcontroller is a PICAXE-08M2 integrated circuit. The PICAXE-08M2 microcontroller is an eight-pin integrated circuit. The chip has flash memory, thus allowing it to be programmed easily. Figure 4.5 shows a photo of a PICAXE-08M2 microcontroller:

The LED MC is pre-programmed with 21 arcade-based games. Some of the game titles are binary coded decimal, changing speed, the baseball game, and home run derby. The arcade games are accessible using a selector switch and a sequence of instructions. Several snaps provide various electrical control functions that allow the LED MC to provide the arcade games previously listed. Figure 4.6 shows the LED MC with its snap functions:
