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), 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.

I want to be able to use the Arduino Due PWM at higher resolution and frequency than what is available by default. I use IDE, that was the most recent a few.
Arduino timer interrupts allow you to interrupt frequency (Hz) (Arduino clock time it takes to pass by a switch mounted on the frame.
The Atmega328 (as on the Arduino Uno) has three timerscounters onboard the chip. Timer 0 is set up by the init() function (which is.
Secrets of Arduino PWM et Changing PWM Frequency on the Arduino les 8bit TimerCounter2 with PWM and Asynchronous switch off PWM.
In other words, with Arduino's PWM frequency at about 500Hz, the green lines would measure 2 milliseconds each. A call to analogWrite() is on a scale of 0.
1 Basic PWM Properties In these notes we will describe the use of PWM on an Arduino for the basic principle of using a transistor to switch a load is.
Pulse Width Modulation Using an Arduino Pulse Width Modulation, Arduino, Frequency is the inverse of the period or total time it takes
The Arduino has a fixed PWM frequency of 490Hz And it is possible to change the PWM frequency to a higher (or lower) frequency by altering the timer prescalers.
I will only describe the simple timer modes all timers have. Pulse Width Modulator The PWM frequency show the PWM frequency in relation to the timer.
If you\'re like me, then you have a small pile of clothes on the floor that may or may not be dirty. This could include jeans, dress shirts, and barely worn shorts. So how can you tell which clothes are clean or dirty? I came up with a way to track various articles of clothing using NFC and a 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.
LIDAR (Light Detection and Ranging) is an optical remote sensing system which can measure the distance of a target by illuminating it with light. LIDAR technology is being used in Robotics for the perception of the environment as well as object classification.
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.
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.
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.
This project can be useful for you if you have a website that you can use to keep the data. The common way is to set the ESP8266 to server mode and connect to it from the internet by entering your router IP address in a browser. My internet provider don\'t let me do that by changing my IP address each time I enter the IP address.
