  1. Hi Rui,
    I thought I would look at this email from you as I had nothing to do for 5 minutes. I am so glad I did… I have ordered two prototype shields – they will do just great for a project I am doing right now. Thank you for taking the time time to compile this list as it was very interesting, I had no idea they made some of these boards.
    Thanks very much.

  2. This list is really useful.
    I also downloaded your 18+ projects tutorial some time ago. Haven’t had time but am looking onward to doing some soon.

  3. Hi,
    I just got the WIFI shield (24. ESP8266 Wi-Fi Shield) and I don’t know where to start from… Should I flash the module first or it’s ready to use out of the box ?

    Having some demos code would help and a description of the options to.

    I’m planing to use it to collect datas from sensors and send them to a mosquitto broker service on my network.

    any help would be appreciated.

  4. Thanks for sharing this helpful list! I myself am in the PCBA business, so I’m always interested in stuff like this. An easy but excelent list I must say 🙂

  5. how do i program the arduino along with ethetnet shield to control the devices from any where in the world?
    the code provided in your book 18 adruino projects can be used to control the devices in the single LAN.

  6. First, your tutorials have been extremely helpful in rapidly coming up to speed on both ESP32 as well as implementing many IOT areas I was not familiar with. Great tutorial subjects and very easy to follow/learn/implement -THANKYOU!

    A Question: What is your recommendation for how to best connect a ESP32 to the standard physical shield layout?

    Is there a adapter board to MCU32, etc or a ESP32 in a Arduino physical format?

    Thanks again!

    • Hi.
      To use the shields with the ESP32 you need to check the shields datasheet to see which pins they use to communicate with the board. Then, you can use wires to connect the pins used by the shield to the ESP32. There is an ESP32 in an Arduino formart: the ESPduino32. However, I don’t think these shields are compatible with that board.
      I recommend using sensor modules instead of the shields to use with the ESP32. Here you have a list of some modules: https://randomnerdtutorials.com/21-arduino-modules-you-can-buy-for-less-than-2/
      I hope this helps.
      Regards,
      Sara

      • Appreciate your thorough reply especially about being wary of the pinouts on the ESPduino. Also, it is not very available so your suggestions are well taken.

        Thanks!
