Outcome

In this Lab, I learnt how tu use IFTTT and

Process

I work on this lab smoothly following the instruction. The only problem I met is IFTTT sometimes are not able to send command to the light, and I'm still not sure if it is IFTTT itsown problem or not.

Next Steps

As I mentioned above, I think I need to find out the reason why IFTTT not sending command to my controllor everytime.

Reflection

This lab allowing us to make a hands-on project is very attractive to me. We can start our first IoT product from here.
