Multiplexing arduino pwm duty

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


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!

Rings of Saturn LED Music Visualizing Pendant Light


I made this LED pendant light from plywood, LED strips, and flexible LED channel. Since I designed this for my living room, the music syncing had to be incognito. With this in mind, I used warm white / cool white / amber LED strips, instead of RGB strips.

Smart Living Room (Home Theatre)


I built myself a voice controlled home theatre, with background light, screen and projector control. With an ESP8266 and an Arduino Nano. I\'ve got my girlfriend an Amazon Echo device for Christmas. Some days later I thought that this device on its own, is a little boring. So I promised her to make us a voice controlled smart living room... and this is my way to it.
