I am still on a good schedule to complete my project on time. I have all the materials that I need to complete the build. I have prototyped assembly, LEDs and arduino coding. I put together a small prototype that looks good and is functional. I used a small amount of pillow stuffing to create a small scale version of the cloud that I will build. I created ” lightning bolts” out of LEDs. Each lighting bolt is two to three LEDs wired together in parallel. I put these in different places inside the pillow stuffing. The lighting bolts are plugged into an arduino uno that is powered by a 9V battery. This allows the hardware to be completely hidden in the cloud. I did a simple arduino code to make the LEDs flash randomly like lightning. My initial code for the prototype is below:
I will modify this code to include more lightning bolts and randomize the order that they flash in. But for now this produced pretty good results.
I have begun building my final cloud, and have plans to spend much of my weekend getting as much done as possible. My main concern is the structural support of a larger cloud. I want to be able to hang the cloud from hooks on a ceiling. With all the wires and LEDs and hardware contained within the cloud the weight does add up. I have begun building an internal structural support, so hopefully what I have planned works out, but any ideas are welcome!
