Gobo Treasure - Help Gobo to open each safe. You need to make the binary representation of the denary number. Press the blue button to change the state of the switch, press the green tick button when you think you are ready. If you press the spacebar - it shows the current state of the code entered (in denary)
A great project that I use with my students in class (Thanks Gromko!) I have swapped 2 blocks only so it is not possible to cheat any more by 'spamming' the tick button (Sorry year 9, you'll have to work for it now!!)
