This sketch demonstrates Internet-based remote communication using a companion ‘bridge’ program running on the attached host which sends and receives messages via an online MQTT server. This allows connecting one Arduino to another over arbitrary distances, which we can use as a starting point for building collaborative telepresence. This example is configured to provide for

Keeping track of everything going on in your program can be an uphill battle. The serial monitor is a way to listen to what’s going on in your code by reporting back to the computer over the USB cable. In the Tinkercad Circuits simulator, the Serial Monitor can be found at the bottom of the Code panel

Dear friends welcome to another Instructable! Today we are going to learn how to get the data that this Xiaomi Temperature and Humidity monitor transmits using the Bluetooth functionality of the ESP32 board. As you can see, I am using an ESP32 board and a 2.8” color TFT display. On the display, we display the temperature and

My idea was a box that would play music when you open it. It also has a display with an emoji on it that awakes, greeting you. There is also a LED in it that lights up if you hold the Force-sensitive resistor squeezed between your fingers, while the next loop of the song happens.
