Arduino unveils next-gen IoT, AI, and automotive solutions at EW 2025, celebrating 20 years of innovation with groundbreaking demos and partnerships.

For the experiment, a low-cost system consisted of an Arduino Mega 2560 with an Ethernet Shield connected to a pH sensor and a four-channel relay. In this relay, two 12 V peristaltic pumps, a magnetic ...

Additionally, we design filtering and amplification circuits to optimize the TENG output signal, making it compatible with the Arduino A/D input system─a novel approach that overcomes the typical ...

V3.0 - Using NodeMCU ESP8266 for controlling switches (Relay). Uses RTC (Real Time Clock - DS3231) and NTP (Network Time Protocol) for maintaining time. OLED Display (128x64) for instant updates. A ...
