Please do not listen to the answer selected as the best. SHORT ANSWER: AC and DC switch ratings are very different.LONG ANSWER: This information is not correct. When it comes to switches it is more than about the raw power the materials can handle. It is also about switching speed. When you flip a switch in DC an arc occurs and if the switch does not switch fast enough the switch will wear down quickly over time until it just burns out or catches fire. Since AC is constantly switching direction no arc will last more than 1/60th of a second, so it can handle more switching current. There are demonstrations of this effect on You Tube.

Nowhere does it say which pin is the clock pin. From the code it looks like it is GPIO4 but I can't be sure. Can anyone confirm this? I can't be sure because all I am getting for data is mostly zeros and then some small noise at the end.
