Unformatted text preview: Quick Guide to Proto-Board PB-503 Figure 1. The PB-503 Analog/Digital Proto-Board (Fig. 1) contains a large breadboard area (white area in center) on which you will be laying out your circuits for the first half of this semester. PB-503 also provides built-in circuit accessories to allow construction of various analog or digital circuits. Some individual features and layouts are described in detail below. 1. Breadboard Figure 2. Each proto-board has three breadboard units. Breadboards will be used to place and wire chips for laboratory experiments. Each breadboard unit has horizontal and vertical groups of terminals. Terminals are called tie points or contact points (these are holes where you plug in wires). There are 8 horizontal groups of 25 terminals, 4 in top two rows and 4 in bottom two rows (circled in red in Figure 2). These terminals are wired together within a horizontal group but different horizontal groups are electrically isolated. There are also 128 vertical groups of 5 terminals. These are divided into two sets of 64 groups each. One group of 5 terminals in the top set is circled in blue in Figure 2. Each group of five terminals is wired together but different groups are isolated. The standard DIP (dual-in-line) chips can be plugged between the two sets of terminals in as shown in Figure 3....
