10pcs/lot New Lilypad Button Board Module for arduino DIY Kit

[Music] greetings youtubers I'm Rick the tech enthusiast here with the next Elega lesson number 11 membrane switch module in this lesson we'll become familiar with the membrane switch module provided with the elgu kit and how we can use it with the Arduino for our projects buttons and keypads are commonly included in all sorts of projects so we'll build and configure a simple circuit that's provided in the tutorial to demonstrate the functionality using the Arduino library then we'll create a sketch to connect the keypad using a single analog pin so let's start building the membrane keypad that's included in the kit is a matrix variety the rows and columns of the keypad share common connections this allows for the fewest amount of outputs in a circuit eight lines total when a button is pressed the combination of connections and a little magic of programming tells Arduino what key is pre
