By The Power of Grayskull! You're designing a "She-Ra" toy sword with three components that are to be powered by a single battery. The sword will have a bunch of NeoPixel LEDs inside a plastic case, an Arduino with a speech recognition shield, a volt motor, and an efficient (100%) buck (step down) voltage converter. When on, the toy normally randomly flashes some LEDs. When the user says "For the Honor of Grayskull" all the LEDs light in a bright strobing pattern and the motor spins causing the sword to vibrate. The devices have voltage requirements and maximum current draws as follows: device Arduino with shield NeoPixel LEDs (maximum) Motor voltage (V) 5 5 9 current (A) .500 .500 .667 1. What voltage (V), power (W) and current (A) must the battery be able to supply? 2. If the device is expected to run for 2 hours of peak usage (the user constantly saying "For the Honor of Grayskull") what energy rating does the battery need? 3. You notice during prototyping that when many of the LEDs are on (during the random flashing) and the user says "For the Honor of Grayskull", the motor seems to just start up, at which point the system reboots. What might be going on, and how can you fix it? By The Power of Grayskull! You're designing a "She-Ra" toy sword with three components that are to be powered by a single battery.
