I had a problem with my circuit and I got confused the same way “chandu” did (voltage was coming from GND, leaving output of Pin 7 – RTS with -12v).
This happens because the COM port is not activated/in use. Once you configure WinLIRC to use the correct COM port and leave it open, RTS will output the correct voltage.

My problem turned out to be my cheap unknown “Philips’ TVs IR receiver” (yeah, that’s how the vendor sold it to me), which uses Pin 1 for OUT and Pin 3 for GND.
When assembling the circuit as shown in the schematics and activating the COM port, 78L05 was outputing very low voltage (I can’t remember now, I guess it was 2.39v) and I was receiving constant 0.78v from OUT pin of the IR receiver.
After inverting pins 1 and 3 it’s working now

thx a lot, same problem solved with ubuntu lucid, processing 1.2.1 and arduino 0023 …

just a little tip for newbies connect your arduino board or it won’t work

looking for the solution with arduino 1.0 and processing 1.5 …

Amazing mann!
Really helped!
One problem i faced(really stupid), the single quotes in my editor didnt match with the ones used here… if anyone else is facing a similar problem, pls try replacing the single quotes over here with the ones in your editor

Comment on How to build a +5V regulator using 78L05 / 7805 by James Burrell

Stefan,
The 78L05 is rated to output up to 100 mA. The 7805 is rated 1 Ampere. By the way, the power which the regulator must dissipate as heat is equal to (input voltage-5)*current.
If you put 9 volts in, and pull 1 ampere, this means 4 Watts are produced as heat! You may need to use a heat sink, depending upon your application. Check to see if the regulator gets hot.
