-read in any pulsing signal on Arduino pin INPUT_PIN (defined below), to get its period (us) & freq (Hz), with a time resolution of 0.5us --you can read in any pulse, including standard PWM signals, ...

In SAMD Arduino it is possible to map an arduino pin number to a specific pin on a per-board basis? Is the same possible with the ESP32 arduino version? I only see extra variables like D1 = 7; in ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

In this second article we will see a practical application of the daisy-chained shift registers. We want to use four 7-Segments LEDs controlled by the Arduino board. As you can imagine, that is ...

Hello, I’m excited to review the ESP32 display modules and HMI touchscreens from Elecrow with sizes ranging from 2.4 to 7.0 inches. For this review, Elecrow kindly provided me with both 3.5-inch and 7 ...

The Joystick module is similar to analog joysticks found in gamepads. It is made by mounting two potentiometers at a 90 degrees angle. The potentiometers are connected to a short stick centered by ...

The Arduino Development Platform, at the beginning in 2005, was conceived to be a simple programmable device to be used specifically for art design work. The goal was to create an interface to support ...
