Arduino Stepper Drivers-1/2: Stepper motors are truly interesting, some might say amazing, and they are certainly useful. They appear in many, if not most, precision electronic machines such as 3D printers, flatbed image scanners, plotters, engravers, robotic vacuums, robotic l…
Arduino Stepper Drivers-2/2: In Part 1 of this tutorial there was a basic discussion of the type of coils one might find in a stepper motor. Here it is appropriate to be explicit as to what type of stepper motor leads you may find as a Maker, as this information is necessary to…

In this Arduino tutorial we will learn how to control 8x8 LED Matrix using the MAX7219 driver and the Arduino board. You can watch the following video or read the written tutorial below for more details.
NeoPixel LEDs strip pinout diagram, how to use with Arduino with interfacing example, applications, features, programming and datasheet
In this tutorial we will learn how to control individually addressable RGB LEDs or a WS2812B LED strip using Arduino. The LED strip consist of type 5050 RGB LEDs in which the very compact WS2812B LED driver IC is integrated. Depending on the intensity of the three individual Red, Green, and Blue LEDs we can simulate...
In this IoT project, a NodeMCU and Blynk app will be used to control the color and brightness of NeoPixel LED strip over the internet.
Bit Banging Step-by-step: Arduino Control of WS2811, WS2812, and WS2812B RGB LEDs: Disclaimer: over the past year, a few different libraries have been written for controlling these ubiquitous RGB LEDs by fellow makers from Adafruit, PJRC, and the FastSPI project. The libraries work great, and we should try them all out. &nbs…

Ever wanted to handle a STM32 board with Arduino IDE. Here is a simple way to load program using USB to Serial/UART/TTL adapter, without a bootloader
Custom 16x16 WS2812 Mini Matrix Project: Hey what's up you guys? So here's another Matrix Project made by using an unusual RGB LED Part, WS2812B 3535 Package. 256 RGB LEDs are arranged in a 16x16 grid, WS2812 Addressable LEDs were used so no LED Driver or complex multiplexing circuit has b…
by Floris Wouterlood - July 2, 2024 -- Summary--The ESP32-C3 microprocessor comes in several tastes. One of them is mounted on the ESP-C3 Super-Mini board marketed through various trading platforms. This microboard can be regarded as a direct competitor for seeed studio’s XIAO-ESP32-C3. Very attractive features of the Super-Mini compared with the seeed studio product…

by Floris Wouterlood -- March 2, 2024-- Summary -- An incredibly small, yet powerful and handy microcontroller board is the XIAO-ESP32-C3 made by seeed studio. We wire this board here to a 3.2” diagonal, 320*240 pixel TFT display with ILI9341 controller - SPI connectivity interface and get (expected) nice results. figure 1. Wiring diagram: XIAO-ESP32-C3…
Sooner or later Arduino enthusiasts and beginners alike will come across the MAX7219 IC. And for good reason, it's a simple and somewhat inexpensive method of controlling 64 LEDs in either matrix or numeric display form. Furthermore they can be chained together to control two or more units for even more LEDs. Overall - they're…
