For PI 2 and PI 3 you need to change the base address to this: #define BCM2708_PERI_BASE 0x3f000000For the PI 1 this was 0x20000000

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.

Thank you.

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.
