Analog Input<\/h2>\n\n\n\n

Analog signals can vary anywhere between 0 and 1, whereas digital signals on the Bela have only two states (0, 1). In my project I am using two different types of analog sensors, which are an accelerometer and two potentiometers. I will explain them in more detail afterwards. With these analog inputs you can have a variable control over some parameters and tune them exactly like you want them to be. (Bela, 2021)<\/p>\n\n\n\n

To read from the analog inputs in Pure Data an adc~ object is needed. The incoming signals are sampled at audio sampling rate, so that you can handle them in the same way as audio signals.<\/p>\n\n\n\n

Digital Input<\/h2>\n\n\n\n

As mentioned above, the digital inputs have only two states and are perfect suitable for push buttons. The digital port has to be configured as an input or output. To use a push button it has to be an input of course. If the button is pressed, the input receives the incoming 3.3 volts, and 0 V when its off. In the following example in Pure Data, digital pin 18 is set as an input and pin 17 as an output. (Bela, 2021)<\/p>\n\n\n\n
