This is taking a previous breadboard experiment and installing it in an Altoids tin.
Along the way I include a few tips about soldering.
A few things different from the breadboard project:
I used a toggle switch instead of a slider.
I added an LED so that you could tell if the power is on. This is important because this unit is portable and operates on battery instead of a steady power supply. If the LED goes dim you will want to replace the battery. The downside to using a battery is that the sound will change pitch as the battery weakens.
All the connections are permanently soldered.
The components are hot-glued to secure them and to insulate them from shorting on other components and the side of the tin.
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.
