Many people have attempted to build an electronic circuit board. Did you know that electronics knowledge has to be acquired first? The 'PCB' or printed circuit board is one type of electronic circuit board. When you venture into building your first 'PCB', be patient. It will most likely produce errors or would not work at all. Worry not, as I will guide you towards making your own 'PCB'.
Reasons for using 'PCB' as a desired circuit board is that they are very stylish. No, I am kidding. They do look stylish, though. 'PCB' can fit in many electronic components in an arranged manner. This is because of the copper tracks (can be seen as copper lines) that were designed to go up or down or left or diagonal! Thus, the traditional method of using straight wires are not of use here. This is one advantage of the 'PCB'.
Other than that, a 'PCB' will allow you to learn much more on electronics. Once you have manufactured your very own 'PCB', you will need to test two copper tracks that are adjacent to each other. In other words, both copper tracks that are side by side. Switch your voltmeter or 'multimeter' to connectivity function.
The connectivity function works this way. If you connect both probes onto a straight wire, it will emit a sound. That means the straight wire is connected. The path between the probes are valid, or connected. That is why it is called the connectivity function.
Back to the circuit, testing copper tracks that are beside each other is important. Why? If you get a sound from the voltmeter, that means the two copper tracks are connected. They are not supposed to be connected! Notice the gap between the two copper tracks. When sound is emitted, it means that a shortage has occurred, in this case.
