Which Arduino to buy?

Hi ,

What board I should buy for learning.

Seems like there are lots of different broads.

Uno.
Get a starter kit with a decent sized solderless breadboard and wires like this

Shift registers are also handy, I use this one a lot, great for controlling LEDs, or LED strips that are powered from 12V.

Many thanks for this info

If you don't know what board to get then the answer is "Uno".
