The brightness of the button lights is still a little bit dim. And never mind the noise with the sostenuto function lol. See my previous video for all details. Buttons: https://www.aliexpress.com/item/1005002424453281.html The creation in this video works with multiplexing, but it's far from perfect. The LED's are kinda dim, so i still have to dig into other solutions, perhaps the shift register one. With shift registers you can load in all the required LED states on the background into shift register IC's via serial communication, pull a pin low or high, and it will update all at once and keep the LED's on until the next update. So the brightness should be better. For multiplexing you can have a look at this video: https://www.youtube.com/watch?v=8w09Zy8MQrc (7-segment displays are just LED's, you can drive normal LED's with the same techniques) My code: https://github.com/Engineer9736/OrganRegistrationPanels_public/blob/main/multiplexing.ino Pictures of the hardware: https://github.com/Engineer9736/OrganRegistrationPanels_public/blob/main/IMG_1542.jpg (Yeah i know the cardboard is gross LOL, my cat used to eat on it 😅, deal with it 😛) & https://github.com/Engineer9736/OrganRegistrationPanels_public/blob/main/IMG_1541.jpg The electric schematic is from: https://www.instructables.com/Multiplexing-with-Arduino-Transistors-I-made/
