Gone are the days of plain data visualization! In this tutorial, we are going to create a temperature and humidity Adafruit IO dashboard using NodeMCU. Introduction So far we have discussed three topics about ESP8266. On one of them, we made a simple web server that displays the real-time temperature and humidity of a room….
If this tutorial is what you’ve been looking for, then that is cool! Sorry, I can’t help myself. In this tutorial, we explore IFTTT functions using an ESP8266. IFTT IFTTT, also known as If This Then That, is a free web platform that allows devices to do specific things such as composing an email, posting…
In this tutorial, we are going to explore the pre-installed AT firmware inside the ESP8266. The AT Firmware The AT firmware is a pre-installed software in the ESP8266’s ROM (Read-Only Memory). It uses AT commands which are based on the Hayes Command Set. The Hayes Commands Set are commands for telecommunication operations. For instance, dialing…
Are you itching to connect your Arduino projects to the internet? Then this tutorial is perfect for you. In this new series of articles, we explore the well-known ESP8266 chip. Introduction IoT (Internet of Things) has been the buzzword, the thing for a decade now. The appeal of having your electronics talk to each other…
For the final part of the wired communication protocols series, we are going to discuss SPI, also known as Serial Peripheral Interface.
So far we’ve talked about wireless technologies and UART communications. In this tutorial, we will talk about Inter-Integrated Circuits or I2C. I2C I2C (Inter-Integrated Circuits) is a serial communication protocol that connects multiple slaves to a single master and vice versa. This feature is particularly useful for peripheral devices that log data into a single…
In this new series of articles, we are going to explore wired communication protocols. It will consist of 3 parts, starting with this one for UART. Introduction Wired communication protocols are essential to Arduino. In fact, as I mentioned before, you need it to send a program or else your Arduino remains blank. These wired…
Welcome to the third part of the basic electronics series! This time we are going to discuss everything you need to know about capacitors, a highly underrated electric component, but is essential in Arduino craft. What is a Capacitor? A capacitor is a passive electric component that stores energy. You charge a capacitor by connecting…
Resistors are an omnipresent component on every electronic circuit. Today, we get to learn more about them, their different types, applications, and proper usage. What is a Resistor? A resistor is an electronic component with a fixed resistance value. Moreover, they are passive components, which means they cannot produce energy. They are often added to…
Not everyone in the Arduino craft is knowledgeable in basic electronics. In fact, the majority of Arduino makers are of programming backgrounds. That is why today, we are going to have a little introduction to how electricity works to help bridge that software and hardware knowledge gap. What is Electricity? Electricity is everywhere nowadays. Some…
