Uno R3 Arduino Comp Post as a guest Name. I wonder if there is a rogue datasheet somewhere which has mixed that unusual “W” package pinout, with the “N” package pinout?

Contact Infomation If you have any amazing things you want to discuss with Tinkbox, don’t hesitate to contact us: The fact that at least some datasheets like the TI one show both pinouts, could perhaps allow someone to look at the wrong pinout when switching between looking at the datasheet, and looking at the breadboard, while wiring the breadboard?

How to Make Learning More Fun? I wonder if you have misinterpreted whatever IC datasheet you have been looking at, if it contains that unusual pinout, with Gnd on pin 11? A real schematic rather than a photo of your breadboard might help you get an answer 74ls220 your question.

Your LED will be drawing more than 0. It is interesting that pin 11 is connected to Gnd on the OP’s breadboard, for the reason I explain in my answer. The problem I see is not so much that pin 11 is connected to Gnd; but that pin 7 is not connected to Gnd.

When I throw the switches to the up position, as pictured, the circuit is shorted to ground, which should pull the input pins low, meaning the output pin is high and the LED lights.

However it seems that you have connected IC pin 11 to Gnd. A vatasheet more points: Sign up using Facebook.

I’ve tried the same circuit with a couple of IC’s in case one was faulty, but the same behavior is exhibited.
