Arduino library for the I2C LCD display, typical 20x4 characters. The library is inspired by the excellent New-LiquidCrystal library by F. Malpartida. Therefore the interface is kept quite identical, ...
It’s the moment you hard-core hardware nerds have been waiting for: the reveal of the 2025 Hackaday Supercon Communicator Badge. And this year, we’ve outdone ourselves, but that’s thanks to help from ...
An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...
This proposed Arduino-based automatic bell device is an electronic system that rings bells at predefined times without manual intervention. It is built around an Arduino Uno, which is programmed to ...
A DC load is an essential testing tool for any electronic enthusiast, especially for testing and repairing power supplies. A DC load is an essential testing tool for any electronic enthusiast, ...
4.3-inch ESP32-S3 wireless touchscreen display features terminal block with RS485, CAN Bus, I2C, DIO
Waveshare “ESP32-S3-Touch-LCD-4.3B” is a capacitive touch display development board built around an ESP32-S3 SoC with RS485, CAN Bus, I2C, and isolated DIO interfaces provided through a terminal block ...
For years, there has been a clear distinction between the Arduino and Raspberry Pi boards. There are some things the Arduino can do that the Raspberry Pi can't, and vice versa. When you think of ...
So you finally decided to hop on the Arduino bandwagon and start making electronic projects as a fun hobby. As a beginner getting started with Arduino, your first instinct is typically to buy a ...
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 ...
Abstract: This paper presents the design of an Intellectual Property (IP) that converts a serial output signal into a parallel output signal for a liquid crystal display (LCD). The IP is intended for ...
Last time, we’ve used a logic analyzer to investigate the ID_SD and ID_SC pins on a Raspberry Pi, which turned out to be regular I2C, and then we hacked hotplug into the Raspberry Pi camera code with ...
