Lightsaber

Overview

As avid Star Wars fans, we felt that there needed to be a better more interactive toy for everyone to enjoy as a piece of Star Wars culture. We decided to do this by controlling the sound of the lightsaber based on an accelerometer that could make sounds similar to the movies of waving around a real lightsaber. With the additional button to switch colors and a vibration motor to give the device an exciting feel, this device should provide tons of fun.

Schematic & Layout

Description: Powered by two 9V batteries in parallel (due to our predicted high current draw) we have an LDO stepping down the voltage to 3.3V to power the ESP32. There is then an audio amplifier in order to power our speaker. There is also a transistor to control our vibration motor. We have a signal amplifier that changes the 3.3V PWM signal from the ESP32 to a 5V PWM signal for the Adafruit LED strip and also a 5V converter to power our LED strip.

Big Mistakes & Lessons Learned

• Pull Enable Pin to High

• Double check what components we're exactly getting (Adjustable or not adjustable)

• Make sure Transistor has the right footprint
