V+ on the schematic
« on: January 12, 2006, 04:32:33 PM »
On the schematic, there are two leads going north--one coming off a 10k resistor and one coming off the 4.7 k resistor.  Only the one coming from the 4.7k res indicates "V+".  But on the build pictorial, Aron draws out the schem and adds V+ to the 10k.  Accordingly, he solders the two together at the end of the project and when its wired up, the lead to V+ is connnected from both resistors.

If I hadn't seen the build pictorial, I wouldn't have known to connect the 10k to the 4.7k since there's no symbol telling me to do so.  So, how did Aron know to do that? 

Thanks for the help!

It's just sort of taken for granted that the upward pointing arrows will all get connected together. If a circuit uses more that one supply voltage, a different symbol will get used to show everything that connects to each supply. The ground symbol is the most common symbol that works this way, but V+ isn't far behind.
