New video! On the lower left-hand portion of every Adafruit Circuit Playground Express, there is a small onboard speaker and class D amplifier. This allows you to make some pretty loud sounds! The amplifier is also connected to the true analog output on pin A0, which is marked with a wavy line symbol. You can turn off the speaker and only output through the pin if you like. For this tutorial, we are going to use the speaker and the capacitive touchpads to make a capacitive touch keyboard!
