This example combines balls_demo.py and noise.py by using both cores and reading a potentiometer input to change the speed of the display and song
|
||||
# We're creating 100 balls with their own individual colour and 1 BG colour
|
||||
# for a total of 101 colours, which will all fit in the custom 256 entry palette!
|
||||
|
||||
# This example shows you how you can use Pico Explorer's onboard buzzer as a speaker to play different notes and string them together into a bleepy tune.
|
||||
# It uses code written by Avram Piltch - check out his Tom's Hardware article! https://www.tomshardware.com/uk/how-to/buzzer-music-raspberry-pi-pico
|
||||
# You'll need to connect a jumper wire between GPO and AUDIO on the Explorer Base to hear noise.
|
||||
|
||||
# Create a buzzer on pin 0
|
||||
# Don't forget to wire GP0 to AUDIO!
|
||||
|
||||
# Analogue Dial on a Pimoroni Pico Explorer with Pico Graphics
|
||||
# 10 K Ohm potentiometer center wiper connection on ADC(0) = GP26
|

# Don't forget to wire 3V3 and GND to the potentiometer limit connections
