For my second project I was thinking to build and code connect-4 game. The way I wanted to build the game is for it to have 84 leds (42 of red and 42 of green ) and have 7 buttons for inputting the column to drop the LED.
Since I am a bit new, I was wondering if it is even possible to control that many leds and have 7 input buttons.
By the way I have arduino diecimila.
Thank you
I'd recommend you do some research here:
A fair number of people want to control lots of LEDs

Thank you,
Now I know that the hardware allows this to happen. Before I jump into this I would need to learn about shift registers and such. Any recommendations on a smaller project that will allow me to learn about them?
By the way fantastic looking project. How much knowledge of electronics did you have before you started it?

Start with a single shift register and learn how to control each led individually, then add one more, then try your hand at multiplexing

Virtually none.
