I believe the parts list and how it is connected was covered in the video, does the video not show up in the instructable? I don't remember the cost of the parts. Here is a link to the video on YouTube: https://www.youtube.com/watch?v=IjUlqe-aeGU

In my project Wireless Sensor Node with the nRF24L01 I convert from F to C so you can leverage it from that code

Thanks for the comment and feedback!

Thanks, I am actually thinking of upgrading this project to add WiFi. Let me know if you get it up and running with the ESP8266

If you go to my blog (link in this instructable) and search on the title of the video you will find the Arduino code

Yes you can add a mechanical switch in series or in parallel with the TRIAC.

Hello, I am afraid I don't understand the question. The TRIAC is a SPST switch. Note that AC voltage swings positive and negative so you have current flowing in both directions.

Yes you can add a mechanical switch in series with the AC line power on either side of the TRIAC circuit

You should see a video. Are you in an area that blocks YouTube?
