Adding LEDs to a project soon uses up valuable pins. What if you could control a row of 12 LEDs to show changing values with only 4 digital pins? There is a way and it is called Charlieplexing. It was first proposed in 1995 by Charlie Allen. It relies on two properties that you may …
The Arduino IDE provides a serial monitor window which proves to be quite useful when it comes to printing values to debug a project. However, you can further enhance this functionality by attaching a small screen to your project that can provide feedback, display menus, and show results, improving its utility significantly. Moreover, this modification …
The Philips PCD8544 driver chip is connected to a recycled screen from the popular Nokia 5110 phone. Because the screens are second-hand, the glass cover often has small scratches/blemishes. They are rehoused in a metal box on a PCB with 8 connections. You need to solder on the supplied pins. The screen is a Liquid …

This guide presumes that the user is adept in integrating LEDs, potentiometers, and sensors into the Arduino platform, has worked with SPI and I2C devices, and is prepared to level up and initiate data exchange between Arduinos. Employing this network is more straightforward and more comprehensible than radio communication; however, it necessitates wiring between the …
When you begin creating your own projects, whether using a breadboard or stripboard, you may encounter more complex circuits. You might also make minor mistakes, resulting in projects not functioning as anticipated. This is when you’ll need to learn how to utilize a multimeter to assist in troubleshooting your project. Your issues could be due …
If you’re familiar with Arduino, you’re likely aware of the frequent need to incorporate motors into projects, especially those involving robotics. In a previous tutorial, we discussed using a transistor to control small motors. But what if you find yourself needing to control a larger motor? The solution to this requirement lies in using a …
At some point, most Arduino owners will decide that their next project requires communication between two of their microcontroller boards. You might want to control a long strip of NeoPixels decorating your room from the comfort of your armchair without tripping over cables or read the temperature and humidity of your greenhouse without putting on …
Anyone interested in developing electronics hardware and dabbling in IoT is recommended to start with Arduino projects. This is because the average Arduino kit opens your mind up to the possibilities of building unique ideas from scratch with just a board, soldering tools, and electronic components. The Grove Beginner Kit is one such tool that …
LED strips are one of the most popular light sources in the world today. From car modding, interior design, to cosplay, it’s hard to find a place where LED strips haven’t been used. Their size, ease of use, and fairly low price led them to become a staple for makers everywhere. They also make an …
The world currently makes use of approximately 30 billion IoT devices to build a more interconnected world where information sharing and automation is done with ease. Although a large percentage of available IoT devices are deployed across commercial facilities, the use of IoT for home automation in domestic spaces is at an all-time high. IoT …
Before diving into the naming of the most useful shield for Arduino as the topic highlights, it is only right to provide a little background into shields for individuals who intend to work with one for the first time. Shields are pieces of hardware that give Arduino a specific purpose. That is the short definition. …
As Linux distros go, Ubuntu and Linux Mint are some of the more popular options out there anyone interested in using an operating system outside of the big two, Windows and Mac, are likely to explore. The reason why a new user is more likely to explore either Linux Mint or Ubuntu is due to …
The interconnected world is expected to change the way every industry functions and usher in industry 4.0 and this includes domestic households. Interconnectivity is expected to be driven by the Internet of Things (IoT) which consists of both hardware and the software needed to run entire systems.
