Note: The code is intentionally heavily commented to provide maximum assistance to those who wish it. You can also download the files (with fewer comments) from my GitHub. // Enable WiFi connectivity and secure communication over the internet #include...
Before we dive into the hands-on part, it might be beneficial to consider making a 3D-printed casing to protect our ESP32 board. In the downloads section, you'll find the STL file for a case designed to comfortably house the electronic board. ...
The 3D-printed casing is designed with a hole on one side for routing the IR sensor's cable, and on the opposite side, it features a space to accommodate a USB cable. For powering the board, I've opted for the simplicity of using a USB port. This...
An XIAO ESP32C3 microcontroller and an XIAO extension board manufactured by Seeed Studio comprised the heart of this project. It comes with rich peripherals that include an OLED, RTC, SD Card Sot, passive buzzer, reset/user button, 5V servo connector,...
Initially, we had the idea of reviving an outdated CASIO vintage watch frame that I had with the XIAO expansion board. The expansion board contains the display, microcontroller, RTC and even the battery, so we prepared a rectangular holder that will...
Next, we connected the JST connector of the expansion board to the JST connector of the LiPo cell.Next, we insert the battery into the top part and secure the expansion board in its proper position.Next, by using four m2 screws, we secure the expansion...
Here's the end result of this super-small build: a digital wrist watch. The XIAO expansion board serves as a functional clock module in this useful and functional watch. The inbuilt buzzer can be used as an alarm indicator should we introduce an...
Now download the Arduino Code from below. Read the instructions in the code line by line. First, you have to change your wifi name and password. Then scroll down and in the http.begin function change the website from "electronoobs.com" to the...
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...

Setting up a basic breadboard version of the project, which consists of three push buttons connected to one 1K resistor each between VCC and GND, is the first phase or level. When the button is pressed, a value is obtained at the GPIO Pins, which is...
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...
We attached a 3.7V LiPo Cell via the JST connector on the expansion board after soldering the Switch PCB and the expansion board together. Our little 100mAh 3.7V Li-Po cell provides 0.37Wh of power, which is more than enough for this tiny portable setup....
After assembling the Switch PCB and XIAO Expansion board, we model both components in Fusion360 and create a robust enclosure that holds the XIAO, which is connected to a battery and the switch PCB. We incorporated the XIAO Expansion board on top and...
In order to complete the build, we connected the JST connector of the LiPo cell into the expansion board first, and then we placed the LiPo cell into the 3D printed base.Next, we position the switch PCB and expansion board on the expansion board in their...
