Before we begin!

 There are a number of safety precautions included in the product, but that can not

account for human inexperience and error. This product and the example below interacts with 

HIGH

 AC

voltage and so is intended for people experienced around, and knowledgeable about 

HIGH

 AC voltage. If

that's not quite your jam, then take a look at our IoT Power Relay! It's not I C but the IoT Power Relay
contains shielding to prevent accidental shock.

Required Materials

For the example under 

Hardware Assembly

, I used the following materials to control a load (i.e. a lamp). You may

not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust
the cart as necessary.
