Build your own lightning detector that's smaller, more customizable, and cheaper than a commercial one!

A low-cost stick designed for blind people that enables them to walk without any assistance.

How to make a Aquarium Water Cooling System

We will be interfacing the high powered E32 1 Watt LoRa module from eByte with an ESP32, the same method is used for an Arduino or ESP8266.

How to realize an alarm clock controlled by a smartphone, using simple raw materials and an Arduino-based ESP32.

stick the flex sensor on the surface where the cup and the cup mat are in contact with each other.

This project includes hardware which will measure blood pressure, heart rate, ECG & temperature, and send to Android application & Firebase.

This is an EMG sensor I bought from DFRobot. An EMG sensor can detect surface electromyography to reflect muscle and neural activities of human. Combining with a rabbit hat and several other stuff, it was evolved into a clever hat that can detect human facial expression such as scowling, grimacing, shocking, etc. Put the dry electrode to the area to be detected, the sensor will output analog signal to indicate the intensity of muscle activities. Let’s speak less and just get started!

I want to turn on the light simply by lightly knocking on the table. Therefore, I use this BMI160 gyroscope accelerometer as the ultra-sensitive vibration switch.

Recently I bought a 6-Axis Inertial Motion Sensor from DFRobot. So it occurs to me that why not make a wristband pedometer to calculate my physical strength.

Off the top of my head, colors can be represented by the matrix screen. Why not make a Pixel Style, Bluetooth Player to represent our colorful expressions. Followed by detailed tutorials presented by DFRobot, you can make your own Bluetooth Music Player.
