What is the HC-05 Bluetooth Module? The HC-05 Bluetooth module is a simple, versatile, and low-cost device that enables wireless communication between devices like Arduino and a smartphone. It uses ...

Serial data logging is still one of the fastest ways to capture bench data from Arduino, ESP32, STM32, Raspberry Pi Pico, RS232 instruments, USB CDC devices, scales, meters, test fixtures, and custom ...

I like to visualize things, so I decided to prepare this simple tutorial to help you better understand how to visualize data using Arduino. This tutorial assumes that you have some basic electronics ...

Every new generation of computers repeats the techniques used by the earlier generations. [Kim Salmi] created an ASCII-based quadcopter simulation game using an Arduino that displays on the Arduino ...

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...

I would like to try running things using an ESP32-based board with Arduino. When it comes to running microcontrollers, the classic starting point is the "blink"—making an LED flash on and off—which is ...

Imagine turning an Arduino and a GSM module (such as SIM900 or SIM800) into a miniature phone: you can dial out or send a message with the press of a button! Here's how to build your own simple ...

[Paul] wrote in to tell us about some interesting Arduino latency issues he helped nail down and fix on the Arduino. It seems that [Michu] was having some problems with controlling his Rainbowduino ...
