This Wire and Loop game is a great project for learning basic circuits, electronics and Python coding
Looking for a quick electronics challenge for the New Year? We love this Wire and Loop game by Christopher Barnatt.
“It’s the game where there’s a bent wire,” explains Christopher. “And you have a loop and you have to move the loop around the wire.”
“What I thought I’d do is take that game and add some computing power in the form of a Raspberry Pi,” says Christopher.
“It’s an interesting Raspberry Pi project,” says Christopher “and it might inspire to do other Raspberry Pi products.”
“More broadly it maybe will make us think about what happens when you take a traditional electrical thing and you add some computing power.”
The Wire and Loop structure is connected to the GPIO pins on a Raspberry Pi board. An LED is placed in a breadboard and a simple button is held in some Blu-Tack.
It’s a simple build. But it uses a more interesting take on the usual button and LED circuit.
“What I’ve got here is three GPIO pins in use,” explains Christopher. One GPIO pin is being used an output to run the LED, then other pins is being used as the contact for the wire and the third for the button.
Christopher has placed this circuit diagram online.
He has then created three separate Python programs to go with the build.
We think the Wire and Loop game is a neat project to build. It’s fun to put together and explains the concepts of circuits and connections. It also uses Python to effectively learn how to respond to different inputs and outputs.
