Today Spike and I have finally finished our Microbit project; a combination lock for a cardboard box. It is a bit scrappy and the ease of access is not too good for a user, but when set up properly it does exactly as programmed. The problem with it the past week and a half was the lack of a working buzzer; one of the buzzers from the new shipment fixed these ailments.

I found it challenging to get the foil on the inside of the front side and the outside of the lip of the lid, but using a technique I managed to secure an unbreaking connection by making the both of the lines of foil jagged so it had more chance to touch the other. An unintended effect of this solution is that whenever the environment around the box is manipulated, it has a high chance of triggering the breaking of the connection, so it will go off if someone is trying to tamper with the table that it's on.

I have learnt a lot from the code, particularly how ciphers worked and the formula to make a number combination equal to the key to open a lock, as shown below. I understand all of this code and it makes sense to me.
