Breadboard Overview All of the development boards have a breadboard, allowing components to be easily connected to your PIC microcontroller. Breadboard tie points are organised in groups of five, which are electrically connected together. This arrangement is shown in figure 1. Please note that this shows the breadboard for the 1802 development board. The 2802 and 4002 breadboards are larger, but the principle is exactly the same.
Figure 1. Breadboard tie point connection The development boards also have distribution strips, shown to the left and bottom of figure 1. The left hand side distribution strip (A) gives you access to a regulated 5v supply. The distribution strip at the bottom of the breadboard (B) gives to access to the input – output pins of the PIC microcontroller installed on the development board. The function of each point on a distribution strip is clearly marked on the topside of the PCB. For example, when using a PIC 16F628 with a 1802 development board, the point marked RA0 in figure 1 corresponds to pin 17 on the microcontroller.PICmicro is a registered trademark of
