Uses RTC (Real Time Clock - DS3231) and NTP (Network Time Protocol) for maintaining time. OLED Display (128x64) for instant updates. A webserver for Manual Controls. Vast application including ...

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 webserver ...

This replica uses LEDs driven by an Arduino Nano and a real-time clock. Since the RTC gives hours from 0-23 and minutes and seconds from 0-59, a couple of shift registers and some modulo ...

then I strongly recommend that you go through this “Getting Started with Arduino UNO R4 & Arduino IoT Cloud” tutorial before proceeding. An IoT-Based Weather Monitoring System uses sensors to collect ...

It only utilizes 26µA current in standby mode and 900nA in power-down mode. This module is generally used with microcontrollers like Arduino to create wireless connections between devices. It allows a ...
