Arduino mega external eeprom

Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world. The project's products are distributed as open-source hardware and software, which are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL),[1] permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits.

Similar to eBay, sellers on Aliexpress can be either companies or individuals. Aliexpress is different to Amazon because it acts only as an e-commerce platform and doesn’t sell products directly to consumers.

Automated Staircase RGB LED Lights
Automated Staircase RGB LED Lights


My staircase has claimed a broken toe some time ago. Fortunately, it wasn’t my toe, but I feel for the poor fella. The toe is OK now, but it got me thinking, is there anything I could do to reduce the risk of dealing with another victim? Plus if I could do this on the cheap, that would be super!

Arduino Apple Watch
Arduino Apple Watch


I wanted a smartwatch that showed me notifications from an iPhone, was small enough to wear, and had a rechargeable battery that lasted for at least a day. I created my own Apple watch based on an Arduino. It is a smartwatch based on an Arduino mini pro, which is connected to the iPhone over Bluetooth.

NeoPixel Lightsabers w/ Party Modes -- Arduino-Controlled
NeoPixel Lightsabers w/ Party Modes -- Arduino-Controlled


This project started as part of my Halloween costume, and then expanded...a lot. I ended up making two lightsabers - a Kylo Ren style saber and a Rey / Anakin Skywalker style saber, and creating different Arduino code to simulate each. And, I decided to go beyond the normal lightsaber, and create a party mode with colorful animations on the saber.

Alexa Controlled LEDs Through Raspberry Pi


It turns out that it is quite easy to get Alexa communicate with Arduino via Raspberry Pi with Node-RED. All you have to do is installing two Node-RED modules and setup up a Node-RED Flow with Alexa Local and Arduino nodes. Here I have a project which has Alexa turn on and off two LED lights as a demo.

Driving a Stepper Motor Saved from an Old Printer


Disassemble an old printer (in this case a dot matrix) and drive the stepper motor(s) for linear motion or rotation. With Arduino.
I need some linear motion for a new project and I decided to disassemble an old dot matrix printer in order to reuse its stepper(s), by controlling them via a A4988 driver.

Syma S107G Remote Control Helicopter with an Arduino


Some time ago I saw people reverse engineering the infrared protocol of the Syma S107G toy helicopter and I wanted to get my hands on it as well. It is a coaxial helicopter, which means that it doesn\'t require a torque cancelling tail rotor. Yaw is controlled by using the speed difference to a second rotor underneath the main rotor, which spins in the opposite direction.
