Steady! is an old fashioned game of steady nerves. You move a wand from one end of a wire to the other without touching the wire. You can build this project in lots of different ways. If you don’t have a lot of time then use a ready built toy and modify it. The easiest way is to buy The Connex Maze Challenge kit . As supplied it’s a simple series circuit – what we do is break into that circuit, add some additional circuit elements and control it with Python or Scratch.
Alternatively, if you have time (and it’s a lot more fun for the kids) you can make a physical model yourself, scroll down for some custom built model ideas.
As you can see from the image we use this in our workshops, Raspberry Jams etc. It’s also a great ice breaker for school open days.
When the game is wired up there will be two inputs and two outputs:
We introduce a variable called ‘Lives’ in the code – and use it to give three chances to win.
Here are some different versions of the project
We decided to introduce as many bells and whistles as possible on this one. There are flashing lights, a 3D printed moving fairground ride and it even sings a song!
Here are two versions of the Python Code for this project
