Ever wondered about the buttons on your gadgets? What is going on with button matrix technology? A button matrix is a clever way to wire buttons up so that many of them can share just a few wires on a small computer called a microcontroller. In other words, you can have lots of buttons with only a few wires, which is a wonderful way to save money and space in electronic applications.
If you decide to use a button matrix system, it’s not just a cost effective solution but it also makes using stuff easier. Rather than requiring a separate wire for each button, a button matrix allows a whole row of buttons to share the same wires. You push a button, and the microcontroller has enough information to determine which button it was, by reading its row and column. This helps the device react to you promptly and accurately, which makes it easier to use.
There are plenty of great reasons to turn to button matrix technology in designing gadgets. One major advantage that it saves space on the circuit board, since you need fewer wires. This can makeyour gadgetry smaller and EASIER to carry, which isMUYimportant for things like smartphones or tablets. And wiring together button matrixes is cheap and power efficient – all good reasons for building lots of cool projects with them, right?
How to add a button matrix to your next project If you’d like to add a button matrix to your next Arduino project, here’s how. First, determine how many buttons you want to have, and how you will lay them out in rows and columns. Next, you choose the appropriate microcontroller and programming language to use for driving the button matrix. Lastly make the c-board suitable for the button matrix system. If you pay special attention to your planning process, and you take care to properly handle all connections, it's possible to create a button matrix that works for your project.
One of the neatest parts about button matrix technology is its flexibility. Button matrixes can be configured in multiple ways to best suit your demands. That could be, for example, a small 4×4 button matrix for simple tasks, or a larger 8×8 button matrix for more complex jobs. You can even use any kind of buttons such as touch buttons, flat switch etc., in order to improve the device inoperability. Just this alone, there are many possibilities, the button matrix technology is really creative, and there are a lot of new ideas.
