Arduino opto isolator input

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.

Syma S107G Remote Control Helicopter with an Arduino
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.

Arduino Indoor Garden
Arduino Indoor Garden


Gardening in the modern age means making things more complicated and arduous, with electrons, bits, and bytes. Combining microcontrollers and gardening is a really popular idea. I think that’s because gardens have very simple inputs and outputs that are easy to wrap your head around.

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.
