Re: How to drive 100led from arduno
You better consider using FETs for these high voltage switching purposes. Or else you can use Darlintons such as TIP series.

How to switch 12V with Arduino with Transistors or FETs
So many people are asking this question, so I thought to create a topic to discuss about this. Here are the diagrams for both options.
NOTE: D4 and D2 LED symbol represent a LED set (series/parallel) which requires 12V.
1. Transistor 2. FET

Re: How to drive 100led from arduno
Hi Gihan, Your digram explains the issue very well. Basically it is not correct. Consider following options. Logic Level FET one is my favourite. NOTE: D4 and D2 LED symbol represent a LED set (series/parallel) which requires 12V. 1. Transistor switching Transistor.JPG 2. FET Switching FET.JPG I use...

Re: How to drive 100led from arduno
Hi Gihan, First I need to understand more about how you have connected the LEDs. Can you post a drawing please. You need to mention input voltage for LEDs as well. I might suggest you to move to a darlington or better to a FET, but before all that, I need the circuit diagram to understand.

Re: Wireless Digital Clock
Have a look at xBee from Digi. If you are from Sri Lanka, TRONIC.LK has these modules.
