Hello again and a warm welcome to my series “12 Days of Arduino” Day 5. Today we use a photoresistor to alter the pitch of our tone, effectively enabling us to reach every single note, making this a truly practical instrument of 8 bit glory!
Project requires
–Arduino Uno
–Active buzzer
–3x button touch switch
-220 ohm resistor
-4x 10k ohm resistor
-2x 220 ohm resistor
-Jumper wires
-Tip120
-SN74HC595
-Photoresistor
Welcome back to day 4 of 12 days of Arduino! I’m glad you’ve been following this far, things are about to get exciting! Today I take the keyboard and using a SN74HC595 Texas Instruments Shift Register I create a tremolo effect
