I have 2 terminal switches can I use them or do I need 4 and what would they and the usb come under in circuit Wizard program. Also could this device be powered from a battery? If so how?

Hi could you put a schematic diagram of how to wire up an Arduino in place of the Attiny84? As really struggling to program the Attiny84 and happy to use an uno for this project. Thank you so much regards Nick
You can try to light up the array without the code. Attach 5V to a resistor and try to light up each of LEDs one at a time. This will tell you if it is a hardware or software. If the hardware is wrong rewire. If the code is wrong just double check it for errors.
just spent the last 5 hours building this! and.... i messed something up the minute and seconds blink together and the hours do not light up at all.....
