This project implements a multi-laser distance sensing and light control system on an Arduino Nano (ATmega328P).

Let's take a look at LAN Tester, an application that performs basic tests on wired networks. We will examine its advantages and disadvantages.

Four AVR microcontrollers and a WIZnet W5500 Ethernet chip power this cashless vending machine; 10 units were deployed at Rajasthan IT Day 2017.

OneFader turns a volume control slider into Ethernet-based lighting control data using sACN, OSC, and Sig-Net protocols.

Combining High-Speed AHB Bus With Low-Speed EMIF Bus Using A Zero-Delay Bus Coupling Method

AR22 LCU v1.1 adds W5500 TCP logging to an STM32F446 gamma detector, streaming live dose-rate JSON without disturbing the core firmware.

W5500 Ethernet connects an ESP32-C3 Zigbee coordinator to a Raspberry Pi MQTT broker, letting XBee3 relay nodes switch AC loads reliably without Wi-Fi.

Arduino Modbus TCP slave relay timer for SCADA with EEPROM runtime storage and Ethernet watchdog.
