The Digispark board is one of the smallest Arduino boards ever produced and is copyrighted by Digistump LLC. Although it is tiny, it is also very powerful and powered by an ATTINY85 chip clocked up to 16.5Mhz (about the same speed as Arduino Uno boards). So Digispark is simply a...

4 Channel Relay Shield for Arduino UNO is a simple and convenient way to interface 4 relays for switching applications in your project. Very compact design that can fit on top of Arduino UNO. Project requires 12V DC supply, all 4 trigger inputs require TTL signal, Relay-1 to Relay-4...

Hi guys, in one of our previous tutorials, we built a real-time clock with temperature monitor using the DS3231 and the 16×2 LCD display shield. Today, we will build an upgrade to that project by replacing the 16×2 LCD display with an ST7735 based 1.8″ colored TFT display. Apart...

Arduino just announced a new Yun v2 Board with improvements over the older brother. From the Arduino blog: What’s New in Rev.2 Hardware: Much better, more robust power supply New Ethernet connector with a clever mounting solution that enables the use of all possible...

Hi guys, welcome to this tutorial. Today, we will build an mp3 player using an Arduino and the DFPlayer mini MP3 module. The DFplayer mini is a small, low-cost mp3 module with a simplified audio output that can be connected directly to a speaker or an earphone jack. The module can...

Our friends on educ8s.tv uploaded a new version of their FM Radio on breadboard based on TEA5767 module. I have built a new, improved version of the FM radio project, which resolves the issues we had in the previous version of the project. The sound quality the project now offers is...

Simplified Arduino board targets Education. The project is live at kickstarter and has 22 days to go. Students can skip the hassle of constructing the basic electronic circuit which is boring and time consuming. Although it is equally important for them to learn about basic...

Hi guys, welcome to today’s tutorial. Today, we will look on how to use the 1.8″ ST7735  colored TFT display with Arduino. The past few tutorials have been focused on how to use the Nokia 5110 LCD display extensively but there will be a time when we will need to use a colored...
