Mq7 arduino pwm

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.

After some my Arduino project remains unclaimed touchscreen, so I decided to realize my chidhood dream to create a chess program. After a couple of months it wins me, but it is not big deal because i do not have any chess rating, just amateur.

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, Turn On THIS Lamp: Smart 3D Sensor for Amazon Echo


If you\'ve owned an Alexa or any smart speaker and have Smart Home integration, you\'ve experienced this issue where you have to remember the name of the device to control. I have lots of smart home devices and sometimes remembering names of each one is tricky.

A DIY Smart Insole to Check Your Pressure Distribution
A DIY Smart Insole to Check Your Pressure Distribution

Pressure measurement is already used in a variety of situations. It provides information about gait mechanics and has a wide range of applications, i.e. in clinical situations and in sports. In this project the sensors are used to gain insight about weight distribution. Real-time visualization of pressure mapping is also incorporated because it makes it much easier to understand your data.

Want to wirelessly control a Mars rover from your laptop?
You are in the right place, this kit does exactly that. 10 minutes is what it takes to wire up the electronics, it doesn\'t even need soldering. For people who know programming, this kit is more than a remote control robot.

Ternary Chord Keyboard
Ternary Chord Keyboard


In my heart I know we are stuck with the QWERTY keyboard but that doesn’t stop me wanting something different. I have thought about switching to Dvorak or Colemak key assignments but don’t want to deal with the problem of mental interference when I have to switch back to a normal keyboard.
