Safe Cracker

Original number game – https://www.microbit.co.uk/nrjdzu
Improved game – https://www.microbit.co.uk/joryiq
One of the first games I created with the micro:bit was a number guessing game. I wanted to use the built-in compass so that pupils didn’t need to purchase or utilise any additional equipment other than what would be given to them.

Game idea

Randomly generate a number using button A. Guess the number by pointing in a direction and pressing button B. The number will be between 0 and 359.

I originally started using the block editor to make the game but I wanted to see the code. I realise that my pupils will not all want to see the code…they may be scared of the code. Continue reading Safe Cracker

Microbit first use

Wednesday 10th February.

I plugged in the supplied (rather short) USB cable. It was alive and after telling me to press the A and B buttons (It pointed at these to help me), my Micro:bit wanted me to chase the dot! Like a toddler chasing a feather dancing in the air, I waved my device about, chasing the dot and my micro:bit smiled at me! Now what?! I decided to use a longer cable!

I spent time looking at the micro:bit website and familiarising myself with it. All the time thinking, how are my pupils going to explore this site? Which is best, Block Editor or Touch Develop? I wanted to get started straight away with a simple program so I thought of a simple number guessing game that required the built-in compass to guess the number. I refined this in to a different game so it was easier to play.

After school was my weekly code club – I demonstrated some of the features of my game to a pupil whilst, unbeknownst to me, another teacher was stood behind me (A Geography teacher!)

Geography teacher: “I like this…oh I like this!”

I showed the teacher how easy it was to write a new program to just give compass bearings. He liked that too. He pointed north and I showed him that he was correct (Micro:bit said 0) I them pointed south and Micro:bit said 180…perfect.

This coincidental demonstration reinforced the belief I have that this can be a truly cross-curricular device, that can be used across the school in any subject. My journey in to how will be detailed in this blog.
