I decided to build a little LED lightshow that lights up on the press of a button. I really liked the final product. At first the red LED hogged all of the power and none of the other LEDS lit up, because I placed the resistor at the end of the circuit. I realized that I needed to add a resistor to each LED in order to fix this. I then coded it using functions to turn the lights on or off, which helped me understand how to do that sort of thing in Arduino. It also made the code a lot shorter than if I copy-pasted everything. Images and video demo below!

I also began thinking more about how to build my hand-controlled robotic hand. The biggest issue I faced was trying to figure out how to get my hands on a soft robotics actuator, a problem which I wasn't able to solve.
