  • Part 2 - What we need

  • Let's see all the needed parts and also check the schematic for this project below in order to know where to connect each part. We need the 220V to 12V regulator, the solid-state relay, an ESP32S smd version, some SMD capacitors and resistors, a diode,...
  • Part 3 - PCB Schemati

  • The schematic is quite easy. The basic configuration of the ESP32 chip with pullups to 3.3V for Enable and RST pins. The converter module give us 12V so we connect that in series with the AMS1117 regulators of 5 and 3.3V. The Relay circuit is simple....
  • Part 4 - Assemble the PCB

  • First I solder the voltage converter module. For that add 4 male pins. And on top of those pins we add the converter and we solder it. I also add the input and the output terminals. Then I carefully connect a 220V AC cable at the input. Be careful, and...
  • Part 5 - Website + Database

  • Please check my previous tutorial about IOT with the ESP32 in order to understand more because I won’t go over those steps again. In the video below you learn how to make the website, the database, the internet connection and so on. Follow...
  • Part 7 - Full Tutorial Video

  • Now as you can see in the tutorial video, each time I toggle the button on my website, the LED on the NOOBIX board is also turning on and off. But we can also connect it to high voltage. Connect a 220V load at the output. Then we add a cable at the input...
  • LEVEL 2

  • We used a 55 x 35 mm prototype board for Level 2 of this project and added three push buttons to it: two 6 x 6 mm push buttons for up and down, and one 12 x 12 mm push button for fire.Next we added Three 1K Resistor with each push button.The resistor...
  • RESULT

  • Here's the result of this small build- a completely functional portable game console, loaded with the classic space trash game from old Nokia phones. The ESP32C3 chip is the reason that this setup functions flawlessly. Although the code is somewhat lengthy,...
