Temperature and Humidity Chart With OLED Display

Temperature and Humidity Chart With OLED Display

“Today, we are going to discuss about a digital thermometer that displays information concerning temperature and humidity, which are read by a sensor and stamped on a color chart, all in real time. In this Project, I explain the use of the serial OLED display, which is a 2c display that enables the printing of data using an AM2302 DHT22 …

Web-Connected SMART LED Animation Clock With Web-based Control Panel, Time Server Synchronized

Web-Connected SMART LED Animation Clock With Web-based Control Panel, Time Server Synchronized

“The story of this clock goes back a long way - more than 30 years. My father pioneered this idea when I was just 10 years old, long before the LED revolution - back when LED’s where 1/1000 the brightness of their current blinding brilliance. A true innovator, he coded in assembly language and hand wired each individual LED (an …

Word of the Day Display With IoT

Word of the Day Display With IoT

“In this Instructable, I’ll show you how you can build a “Word of the Day Display” using NodeMCU Wi-Fi module and a Dot Matrix Display. Instead of word of the day, you can display anything you want (text) from the whole internet, after going through this tutorial. If this is your first time using a Wi-Fi module, then also …

Build a Cryptocurrency Tracker With ESP8266 and Arduino

Build a Cryptocurrency Tracker With ESP8266 and Arduino

“Why? With the latest craze in the world of cryptocurrency and, as coin hodlers ourselves, we wanted to have a tiny desktop display cycling through the current prices of different coins. Although we can certainly find the same information using apps and websites (for free!), we discovered that having a dedicated device on our desks displaying the data constantly minimized …

NodeMCU Remote Multisensor With OLED/MQTT

NodeMCU Remote Multisensor With OLED/MQTT

“More than just a pretty (OLED) face - this multisensor (temp, humidity, motion, etc) has MQTT data for your home automation system, as well! This project is my homemade/DIY temperature/humidity multi-sensor, based on the NodeMCU ESP8266, and a DHT22 sensor. It uses a custom-made breakout board for the NodeMCU/DHT I designed in Eagle (available at PCBWay: https://goo …

ESP32 With RFID: Access Control

ESP32 With RFID: Access Control

“How about a method of automatic identification through radio signals that can bring you security and control the access of people to a certain location? This is possible through radio frequency identification or RFID from the English Radio Frequency Identification. And it is the assembly of this system that I am going to teach you today. This system works with …

ESP8266 Connect WiFi Made Easy

ESP8266 Connect WiFi Made Easy

“If you use ESP8266 with Arduino Core you will certainly be issuing instructions: WiFi.begin(SSID, Password). It can connect WLAN easily but the access point to be connected is fixed and inflexible. Whenever the access point to be connected changes, do you rewrite the sketch and upload it? You use AutoConnect as an Arduino library, you forget time and …

Minimalist Iot Clock (Using ESP8266, Adafruit.Io, IFTTT, And Arduino Ide)

Minimalist Iot Clock (Using ESP8266, Adafruit.Io, IFTTT, And Arduino Ide)

“In this tutorial I’ll show how you can make a minimalist clock synchronized with the internet. I tested this with two different ESP8266 based boards: Firebeetle and NodeMCU. The microcontroller gets current time from a Google server, and displays it on a NeoPixel LED ring. It also receives current weather data from WeatherUnderground, using IFTTT and Adafruit.io platforms …
