CIRCUIT
CIRCUIT
This circuit includes 2 circuits each with 5 LEDs wired in parallel. Each circuit has its own positive connection to a micro:bit pin, and the negative connections all go to the micro:bit's ground pin. Each other LED in the circuit piggybacks off of the LED with the positive and negative connections.
ASSEMBLING THE JACKET
ASSEMBLING THE JACKET
Once you find an old jacket, position the LEDs on the back in an arrow shape and cut holes to fit them in. Use hot glue to keep the ends secure.
Measure the length between where your LEDs will start and where the micro:bit and battery will be.
Solder the wires for the LEDs to the power (micro:bit) and connect the appropriate pins to run the code.
Depending on how you modified the code, the left signals could start flashing when button A is pressed and the right signal flashes when button B is pressed.
If you included the code for the low battery alert then find a way to position the micro:bit in a place where you can easily see it like on your wrist or a lanyard.
Make sure that you are soldering in a well ventilated area to avoid inhaling the fumes and watch the soldering tutorial video a few times before attempting this project.
Get help from a parent or a guardian when working with a soldering iron.
