A few years ago, I rescued a pair of nice headphones from the trash and replaced the original speakers with better sounding Sennheisers.
Then, I changed the jack cable for something fancier (and I must admit, less practical).
Now, it is time to put the headphones on the operation table once again to cut the wires..
Because I wanted to keep the headphones as much in their original state as possible, without adding holes, I decided to use the original potentiometer for control and volume. This means I had to find a way to detect a press on the potentiometer. For the bluetooth part I will use the Microchip BM62 Bluetooth module. It’s really cheap and has everything already built-in (Bluetooth LE, a serial interface for control, pins for LEDs, a battery charger and an audio amplifier).
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
