ESP32 OTA Updates: Remote Programming
The ESP32 supports OTA (Over-the-Air), allowing you to update sketches wirelessly. OTA is especially helpful when the microcontroller is hard to access or if you want to make changes without a physical connection. In this tutorial, you will learn how to set up OTA and go through a step-by-step example project: a blinking LED whose…

Arduino Alarm System with Sound Sensor
In this project, you’ll build your own Arduino alarm system. It consists of three components: a sound sensor, an active piezo buzzer, and an RGB LED. You’ll use the sound sensor to measure the ambient noise level. When certain thresholds set by you are exceeded or not met, the RGB LED will light up green…

Recognizing Complex Gestures with AI and your Arduino
In this project, you will develop an AI model that can recognize complex gestures like circular movements and waving. You will then load it onto your Arduino Nano 33 BLE Sense and display the recognized movements in the terminal of your PC or Mac. With this setup, you can later build more sophisticated projects, for…

Arduino Code Lock with Keypad and Servo Motor
In this project, you’ll build a Arduino Code Lock using a membrane keypad and a servo motor. Only by entering the correct combination will the servo motor move and potentially release a lock. Connecting the Membrane Keypad For a code lock, you naturally need a device to enter the code. The 4×4 membrane keypad is…

Baby Monitor with Sound and Motion Detection
This project revolves around monitoring babies’ and young children’s sleep: You’ll build a baby monitor consisting of two ESP8266 microcontrollers connected via ESP-NOW. On the first microcontroller, you’ll connect a PIR sensor to detect motion and a sound sensor to measure noise levels. The data is sent to a second ESP8266, which is connected to…

Automatic Plant Watering With An Arduino
If you trust your Arduino more than your green thumb, this project is right for you. A sensor monitors the moisture in the soil – as soon as a certain value is undercut, a water pump starts up and waters your plant. Once the soil is moist enough again, your Arduino stops the pump. Discover…
