A Halloween speaking clock primarily based on a Raspberry Pi Pico #RaspberryPiPico #CircuitPython #Halloween #PiDay @RaspberryPi « Adafruit Industries – Makers, hackers, artists, designers and engineers!

This venture is a Halloween speaking clock that performs sounds each hour. Only some exterior elements (straightforward to supply and solder) are wanted.

The Raspberry Pi Pico attracts about 1.6 mA in it’s lowest energy mode (deep sleep). Appears not a lot, however it's too excessive for a battery powered circuit, as a result of they'll exhaust in round two months. For that cause, an exterior energy circuit that may shut off the board fully was added. After that, energy consumption was lowered to 70 uA, so batteries will final for a yr.

The Pico acts as sound storage and participant. To indicate the time and generate an hourly sign, a quartz clock motion with set off was used. Combining these 2 components, a speaking sound clock was born.

For software program, two variations of the identical software had been made: one developed in CircuitPython and the opposite within the C/C++ SDK. There’s no must recompile code (within the app developed in CircuitPython) to alter sounds
