A few months ago, our team began development on what will become the third iteration of our BlockyTalky program editor. It uses the Microsoft MakeCode editor (like the BBC micro:bit editor), also known as PXT, that provides creative programmers the ability to program the Raspberry Pi hardware using a familiar, blocks-based editor suitable for those with little to no programing experience. Currently, we support the GrovePi+ shield for Raspberry Pi 2 and later, but additional libraries (such as Internet messaging!) are forthcoming.
The example program below shows the process of building a program that turns an LED on and off on an interval controlled by a knob. Higher values on the knob correspond to a longer interval.
