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.
Arduino has a small limitation in sprintf function that does not print correctly float numbers. The following test sketch demonstrates the problem

Arduino is an opensource electronics platform based on easytouse hardware and software. It's intended for anyone making interactive projects.
I am reading a string which i have to convert into a float with a maximum of precision. I didn't want to use toFloat() float precision in arduino.
Unlike other platforms, where you can get more precision by using a double (e. g. up to 15 digits), on the Arduino, double is the same size as float.
Video embeddedThis video describes and shows how to display more float digits in Arduino serial terminal.
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.
You may have seen these fun, fluffy clouds hanging in someone\'s house or office as light fixtures. We\'re going to adapt the design to be a wearable. Yup, a giant, fluffy, cloud shaped wearable. Also, it won\'t be cloud connected, but it will use a button to change patterns, which for our purposes actually works better.
NetSensor is an Arduino Kit which allows you to monitor your room from anywhere in the world via Internet.
All you would need is a browser and this kit has all the hardware required to monitor your room and check if its warm, not too humid and if someone has broken into your home.
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.
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.
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.
Andruino R2 is an open educational low-cost (components about 35€/USD) modular and extendable mobile robot based on Android and Arduino, integrated in the cloud, to be used as an educational tool in labs and classrooms of STEM, ICT vocational training or engineering courses, as well as in e-learning or MOOC courses as an alternative or, complementary, to virtual labs and soft robotics simulation.

Hi Guys, I have a decimal value stored in a float, and I need to display it on an LCD screen. The LCD library only accepts strings, and since arduino doesn't support.
Displaying FLOAT variables in Arduino. It seems that the Arduino software doesn't have much support for displaying float variables, LCD Backpack V2.
Hey gang, on a project i'm working on it all works fine except for printing floating point values. I had been using serial. print for debugging until I discovered that.

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.
Sprout is a Modern Indoor Planter which automatically waters your plants, herbs, vegetables, etc and will revolutionize your gardening game.
It consists of an integrated water reservoir from which water is pumped & keeps the plant\'s soil hydrated.
