In a previous post - 'Dancing' Snowman - ok flashing LEDs to music - I played with Microbit V2 with its built-in microphone in combination with a Ryan Walmsley's SnowPi RGB  https://www.kickstarter.com/projects/ryanwalmsley/snowpi-rgb-edition  to make a Snowman that reacts to music. In this post, the aim is to show the idea been extended to a Cube of programmable LEDs the 4tronix's Cube:Bit . Essentially the process is the same as the previous post the microphone detects the sound level and cause an LED to light up.  Only a few minor changes were made to the code from the previous example. - The Pin had to be changed from 2 to 0 in the code (see Figure 1); - Increase the number of pixels/LEDs in the settings (see Figure 1); - It no longer chooses random LEDs/pixels to light up; but alters the first one and shifts the result to the result to the next one - so the lights shifts through the LEDs (see figure 2); - Add in when it is quiet set the first LED to set a value...
