In my first post on the Annoying CAPS LOCK Warning Buzzer, I concluded with a list of future improvements to make to the project. Those updates are now implemented and the Annoying CAPS LOCK Warning Buzzer is more robust than ever. Read on to find out more about the improvements.
Goals for Improvements
The list of new features and improvements is pretty short:
Include a ground plane on both sides of the board. Route +5V as traces.
Add some basic ESD protection.
Add a button and LED to use with a USB bootloader and firmware update utility to apply firmware updates.
Make the button and LED accessible without disassembling the buzzer.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
