This is the Diploma Project, it is a jukebox that plays songs using a piezo beeper to play music and some LEDs to go along with the music. The final version will use an Attiny85 (or any other Attiny with 8KB+) There's a button so you can change the songs and will be powered using USB-C

The LED marked "LED3" was connected to the Reset Pin (1) on the Attiny, which blocked the whole thing from working. After cutting the trace and/or desoldering the resistor connected to LED3 fixed the issue.

The next problem was the Piezo Buzzer; uploading a code only caused it to vibrate, sounding like a vibrator. After further testing using a Breadboard, the solution was to move the Buzzer over to Pin 4. On the board, the buzzer was on Pin 3.

The Attiny has specific timers on specific pins, one that is better and one that is kinda meh The Buzzer was on the kinda meh timer and it needs to be on the good timer.

Moving the buzzer to the good timer made the audio sound better, but yet another new problem arose. The Music sounded very corruptet, it turned out it was pressing the button which had been moved to the kinda meh timer.

Moving the button to one of the regualr pins made the music and the button work.

The only problem now is getting the remaining LEDs to work

The Attiny85 is a CMOS Low-Power 8-Bit Microcontroller based on the AVR enhanced RISC architecture, providing the following features:

• 8 Kilobytes of Flash Storage


• 512 Bytes of EEPROM


• 256 Bytes of SRAM


• 6 General Purpose Input/Output (GPIO) lines


• 32 General Purpose Registers (GPR)


• 2 Timers/Counters


• 1 x 8-Bit Timer/Counter with compare modes


• 1 x 8-Bit High-Speed Timer/Counter


• Internal and External Interrupts


• 4-channel 10-Bit Analog to Digital Converter


• Programmable Watchdog Timer with internal oscillator
