Scrolling text with Arduino Uno and MAX7219 Led Matrix

MAX7219/MAX7221 are compact, serial input/output common-cathode display drivers that interface microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. If you want to connect a few of these cheap led matrixes that are based on MAX7219

Arduino-OTTO-STM32 [STM32F469BIT6]

New kid on the block. ST Microelectronics joined forces with Arduino and they delivered the a model with the code name Arduino Star Otto (ARD-OTTO-STM32). It is the first board that includes high-performance graphics, display support, and Wi-Fi link to enable users to create connected systems

Attiny85 arduino

ATTiny85 – Small and efficient

When you are in a need to control or measure just one thing and there are no high expectations in speed or memory there is absolutely no reason to use a microcontroller like Atmega328p(the one you can find in Arduino Uno). You should consider the ATTiny85


Arduino wifi sheild with Esp-01

So if it happens to be the owner of the very first esp8266 modules, the Esp-01’s, you already know that it is not that simple to physically connect them to an arduino board due to pinout. You will need either to bend the pins to

coin acceptor

Add a coin acceptor to your arduino project

Have you ever wanted to make your own coin-operated arcade game cabinet, jukebox, or claw machine? Rachel Weil walks through how to wire up and write code for an Arduino and a programmable coin acceptor. [00:40]  Review of materials needed [02:42]  Setting up the coin acceptor [04:02]

Espruino pico

Espruino Pico

Espruino Pico is a tiny USB stick that runs JavaScript code (it doesn’t need to be plugged into a computer). You can program it with nothing but a serial terminal program, but there’s also an IDE that runs in the Chrome Web browser. It’s got

Arduino Internet of Things Manifesto

The Internet of Things can change the way citizens live, travel, and take care of each other. These developments are being supported by large corporations as well as startups. Arduino has been part of the conversation since early on. We believe that the best way

Arduino mini plotter [vids]

I started making a mini plotter based on the Arduino platform mostly because I was cleaning the storage room and I found some old cdrom drives laying around. So instead of throwing them away I thought that it would be a good idea to use
