-Can't do this in macOS. Will try to do this later on a windows system...   
+The BBC micro:bit is a pocket-sized computer that introduces how software and hardware work together. It has an LED light display, buttons, sensors and many input/output features that, when programmed, let it interact with the world.  
 
+Microsoft MakeCode is a free, open source platform for creating engaging computer science learning experiences that support a progression path into real-world programming.
+
+It has a simulator, a block editor and a javascript editor.   
+
+To explore a different workflow, I will document the simple workflow to make a digital dice, using a micro:bit and MakeCode.  
+
+Basically, on shaking the micro:bit, the accelerometer input triggers the creation of a random number between 1 and 6 and displays it on the LED grid output in dots.  
+
+First, open the editor(https://makecode.microbit.org/#editor) and select blocks. This is an easy graphical interface, that generates code according to the logic of the blocks arranged.  
+![](./images/ep/screenshot.jpg)
+
+1. Define the logic - on shaking the accelerometer is active, first the previous display needs to be cleared, then a random number between 1 and 6 is generated. Corresponding to the number the screen displays the LEDs in the defined graphical pattern. I made some custom patterns for the numbers.  
+![](./images/ep/blocks.jpg)  
+
+This can also be done using javascript or python.  
+
+2. Simulator display
+To display the effect of the code, you can simulate it on the screen.  
+![](./images/ep/simulation.jpg)
+
+3. Download hex file and upload onto micro:bit  
+Instead of compiling and programming, it is as simple as this - downloading the hex and uploading it onto the micro-bit that is connected to the computer through a USB.  
+![](./images/ep/connection2.jpg)
+
+4. Done
+On shaking the dice, it shows the patterns.
