First, build the Circuit: Power + Arduino + Synth Speaker + Long LED. Be sure to connect the synth speaker to pin D9.
Switch the analog/pwm switch to the PWM side.
Upload the Twinkle Arduino program to the Arduino IDE. Also, upload the pitches header file to the Arduino Library.
Once it is uploaded to the Arduino Bit, you will hear the Twinkle Twinkle Melody! Enjoy & dance the night away :)
