So, if the pin layouts on a tutorial don’t match the ones I’ve got on my ESP32, I’d look at what protocol the sensor uses, go ...

We've all heard that "if you want something done right, you have to do it yourself." And that’s usually fine when it comes to tasks at work or baking your own birthday cake. But if you want a specific ...

In this tutorial, we’ll use the Arduino Uno R4 WiFi’s built-in DAC and LED Matrix to build a simple signal generator capable of producing sine, square, and triangle waves. A rotary encoder is used to ...

Stepper motors are a mainstay in precision control systems, valued for their simple open-loop operation and high torque at low speeds. Commonly found in CNC machines, 3D printers, and robotics, they ...

Integrating wireless control into brushless direct current (BLDC) motor systems opens up exciting possibilities for applications such as remote-controlled cars, robots, and other innovative systems.

Waveshare has recently launched the RoArm-M2-S and RoArm-M2-Pro ESP32 robotic arms with four degrees of freedom, or 4-DOF for short. The main difference is that the RoArm-M2-S is equipped with ...

The version of ArduinoFFT has been updated from 1.6.2 to 2.0.2, so the sketches are now compatible. ArduinoFFT versions of other sketches were also modified to 2.0.2. Begin programming SDR radios with ...

We’ve all used a scale to determine the weight of something at some point in our lives. Using a Load Cell or Weight sensor you can add this capability to your Arduino projects. In this tutorial we ...

If you have ever wanted to create your very own modular macro keyboard or can’t quite find the one to specifically suit your needs and would like to design one for specific tasks. You are going to ...
