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.

PNP Transistor as a Switch circuit for interfacing button key pad or switch matrix to arduino uno using minimum Two Input OR Gate Using NPN Transistor.
We are engineers and also hobbyists who passionately involve in embedded system and software projects. These development boards are the best value kits to start your first microcontroller projects.
All my servos are a little bit different to each other - I\'ve built a rig to measure what PWM values turn my servos to a specific angle.
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.
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.
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.
Neopixels or WS2812 what the real name is are amazing LEDS nothing is impossible, and i will proof that this year on this platform for YOU.
This cool kit allows you to control any electric appliance from the internet.What does that mean ?That means you can turn ON/OFF any appliance at your home from your iphone, Android, ipad, PC or laptop from Anywhere in the world..As long as you have access to a web browser.
Connect a transistor to the microcontroller. The transistor allows you to control a circuit thats carrying higher current and voltage from the microcontroller.
Electronics Tutorial about the Transistor as a Switch and using the Collector current and voltages are exactly the same as for the previous NPN transistor switch.
Transistor Switching. up to a load and then switch on and off using an Arduino. I'm thinking of using an NPN high to switch the transistor.
Free Arduino Tutorials, NPN Transistor Sketch (P2N2222AG) using PWM so don't blame me if your arduino, or transistor blows up.
Intro: Simple Transistor Switch. This is a simple but very basic challenge. Challenge: Make this go on and off using a transistor and the Arduino. Step 1: Cutting.
Arduino: figuring out transistors and use an NPN transistor in commonemitter mode. If I wanted to switch it on when the output from the Arduino is.
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.
Android is a great platform to start building your apps, but its not the simplest to start with. For that reason we at hobbyist have built a kit which will take you through the process of building an App step by step.
