Breadboarding a prototype circuit is one of the options. A breadboard is a reusable, solderless device that allows building a prototype circuit, usually for temporary use. Breadboards have strips down one or both sides that are used as power rails. One strip carries the circuit’s positive voltage and the other one is wired to the ground of the power supply. Wire jumper kits provide connectors of different lengths and colors for making the circuit connections on the breadboard. For complex circuits several breadboards can be easily interconnected. Figure 7-3 shows two interconnected breadboards used to test one of the programs developed for this book.

The holes on the top of the breadboard are connected by strips of metal underneath the board. The holes of two rows at the top and bottom are connected horizontally while the remaining holes (in the middle) are connected vertically as shown in Figure 1.12. To connect sensors or modules using the breadboard, jumper wires or single-strand wires can be used.

The first thing we need to learn is how to read a breadboard. A circuit breadboard is a very useful prototyping tool, where components can be added to a circuit by placing them into specific pins in the board. The underside of the board is a series of metal contacts that are connected in columns – except for the power lines on the outside, which are connected in rows (Figure 1.15).

Schematic & PCB fabrication: For schematic and PCB designing, Eagle EDA is used. Initially we prepare schematic sketch & breadboard design and check the functionality, once system functionality is up to the mark then we finalize PCB layout. Here we are designing one layer PCB, for ease of designing. Similarly here we are using all IP components which are assembled into the single layer PCB. After the designing of the PCB layout, we cut the copper plate with the size of 3 × 4 cm. Our designed PCB layout is 3 × 4 cm. After the cutting of the PCB, we print the PCB layout on the copper plate. Now our next target is to start etching process so that the process we are using ferric chloride will remove the copper from the copper plate. After the etching process, we get our designed PCB board. Now the next step is to drill the PCB and assemble the components & start simulation & testing process.

With the circuit schematic diagrams given in Figure 1, a hardware experimental circuit on a breadboard is fabricated. The circuit parameters are listed in Table 1. Two manually winding inductors and four diodes 1N4148 are utilised. It should be mentioned that the negative resistor –RN is realised by a current inverter using an operational amplifier AD711KN with ±15 V sources linked with two resistors (Bao et al., 2016; Chen et al., 2017; Kennedy, 1992; Premlet, 2011). In addition, a 4-channel digital oscilloscope in the XY mode is used to capture the experimental phase portraits.

To minimize cost and optimize durability, layers of medium-density fibreboard (MDF) were used for the main structure, and holes were cut into the MDF using a laser cutter. While the first prototype of the device included a breadboard and wires, the second prototype was designed with a printed circuit board to reduce the weight and make the device more robust. Hole-spacing and diameter were scaled according to braille standards (Braille Authority, 2008). The electrical components allowed for auditory information to be provided to the user and feedback of the user response.
