Today, this channel will try to start into a new area: The area of the replacement of our beloved ESP8266 by the new ESP32. I invite you to join this journey. At the end of this video, you should be able to judge, if you want to order your first board (or take it out of your drawer) Summary: • We checked the GPIOs out, and discovered, that we have many more of them, and that they abandoned the Dx numbering scheme. So, we do not have to write our sketches different for the different boards. • Then, we looked at the different examples provided with the infrastructure. This will be stuff for many videos to come. Today, we tired PWM and it worked. We were able to generate a fading LED, steer a servo, and even create a primitive DAC with this function. • Next, we tried a simple example to check, if the Wi-Fi really works. And it does. We learned, that we will have to change all our ESP8266 sketches, if we want to port them to the ESP32. • Then, I ported my NTP library to the ESP. With one small change, it worked and delivered accurate time also on the ESP32. • At the end, we checked also the new touch pins and, together with the PWM functionality from the beginning of the video, were able to create a small instrument. Attention: If your Arduino IDE is installed in the "Program file" area of Windows, you need to run "get.exe" as administrator.

In this video I build a YouTube subscriber counter using MAX7219 Dot Matrix Displays. Using a simple ambient light sensor, the display adjusts its luminosity automatically. Thingspeak's ThingHTTP app is used to get the information from YouTube. And a FET helps to add a loud beeper alarm to the ESP8266.
