I'm new to using microcontrollers (just got LPC11U24), and I just had a (probably very basic) question to ask: I'm not entirely sure what to do with the Vin, Vout and Ground pins. From what I understand, the 3V connection (I have two AA batteries) is connected across the Vout and Ground pins, but I don't understand what the Vin is for!
I just wanted to build a basic circuit of LEDs controlled through the microcontroller - I'm fairly confident with the programming of it, it's just the connections that confuse me. Do I connect the LEDs across different pins, all connected to the Ground?
I realise that this is probably extremely easy, but I'm self-taught and just wanted to confirm the basics of using the microcontroller before risking it. Thanks in advance.
