31  Using Arduino / General Electronics / connecting two common ground on the breadboard to one on arduino? on: January 06, 2013, 12:20:35 pm
Since i am a newbie,i have a problem regarding joining two common ground on the board.In this case the first led is connected to ground and some pin no. but the 2nd and third led,their anodes are connected to the pin nos. on the arduino board but their cathode is just left on the ground rail on the breadboard.What i am confused is can we connect these two ground from 2nd and 3rd led with the 1st led?

If capacitor blocks dc then why it is actually used in the circuit?
What circuit?

The primary use of a capacitor is to use to store charge.  Blocking DC is just one of the uses.
IT blocks DC doesn't it mean that no current will flow through it?

What other parts do i want to have on hand and where do should i buy them?

That TOTALLY depends on what you do with your Arduino.

Do you use it to light up LEDs? Drive motors? Build robots? Log analog values to SD cards...?



What are the necessary parts to buy in order to drive motors and build robots?
