Arduino Schematics
Arduino is an open-source electronics platform based on easy-to-use hardware and software. It is designed for anyone to use, regardless of their level of expertise in electronics. Arduino boards are commonly used for a wide range of projects, including building DIY devices, controlling home appliances, creating interactive art installations, and more. One of the key benefits of Arduino is its community-driven nature. There are a plethora of resources available online for those looking to learn more about Arduino or troubleshoot problems they may encounter while working on a project. Flux.ai has the world's largest community-driven public library of Arduino footprints, symbols, datasheets, and simulation models. This makes it an invaluable resource for those looking to take their Arduino projects to the next level. Whether you're a beginner or a seasoned pro, Flux.ai has something to offer.

1.8k Uses6 StarsAn Arduino-based Device for visually impaired people
A special wearable device based on the Arduino board. Which can be worn on a cloth by using a strip for blinds. The device is equipped with an ultrasonic sensor, motor, and buzzer. Basic working: When the ultrasonic sensor detects obstacle the device will notify the user through vibrations and sound beeps. The intensity of vibration and rate of beeping increases with decrease in distance and this is a fully automated device. Powering the modules - Connect the 4 Arduino pro mini to a USB male pin and connect to a power bank. For the module in the hand use a small lithium battery. Multiple devices can be placed on person's body as follow: two for both shoulder, another two for both knees and one for the hand. Using the five ultrasonic sensors, blind people can detect the objects in a five dimensional view around them and can easily travel anywhere.

An Arduino Uno powers this autonomous “follow me” cooler that connects to a smartphone via Bluetooth and uses GPS to navigate. The robot cooler connects to a smartphone via Bluetooth and uses GPS to navigate. All the electronics will be contained in the base so that other objects can be carried as well. The electronics were installed in the box cutout under the platform. An Arduino Uno and a 5v battery to power the sensors, Bluetooth, and control logic. A 3s LiPo battery was used to power the motors. A HC-05 Bluetooth module was mounted at the front of the platform for better range. The rest of the components including a L298N motor driver, PAM-7Q GPS, and HMC6883L compass were mounted inside and connected to the Arduino through the breadboard. The compass works with I2C, so we connected the SLC and SDA pins to A5 and A4 respectively. The rest of the pins were connected through digital I/O.

10 Uses4 StarsStrangest LED Blinker TestSite
Project Overview: This project is an enhanced LED blinking circuit that goes beyond a simple 555 timer-based design. It incorporates additional features such as random blinking patterns, speed control, and a start/stop function. The project utilizes a microcontroller, such as an Arduino or Raspberry Pi, to control the blinking patterns, speed, and start/stop functionality. LED Blinking: The board features a total of 8 LEDs that blink in various random patterns. When the board is powered on, even before user interaction, the LEDs start blinking randomly, creating an eye-catching display. Each LED has its own current-limiting resistor to ensure proper current flow and prevent damage. The microcontroller is programmed to generate random blinking patterns for the LEDs, ensuring that the LEDs do not blink in a predictable or sequential order. This random blinking adds an element of unpredictability and visual interest to the project. Speed Control: The board includes two speed control buttons that allow the user to adjust the blinking speed of the LEDs. Button 1 is designated as the "fast" button, increasing the blinking speed when pressed, while Button 2 is designated as the "slow" button, decreasing the blinking speed when pressed. The speed control provides a range of blinking speeds, from a slow, gradual blink to a rapid, strobe-like effect. The microcontroller monitors the state of the speed control buttons and adjusts the blinking speed accordingly. Start/Stop Functionality: A third button serves as a start/stop control. When pressed, it toggles the blinking of the LEDs on or off. This allows the user to freeze the blinking pattern at any desired moment or resume the blinking when desired. The microcontroller handles the start/stop functionality by turning the LEDs on or off based on the state of the start/stop button. Manual Speed Adjustment: In addition to the speed control buttons, the board includes a potentiometer or variable resistor. This component allows the user to manually adjust the blinking speed of the LEDs by turning the knob or sliding the control. The manual speed adjustment provides more precise and customizable control over the blinking speed compared to the preset speeds of the buttons. The microcontroller reads the analog value from the potentiometer and adjusts the blinking speed accordingly. Power and Connectivity: The board is powered through a USB-C or USB-micro B connector, allowing it to be easily connected to a power source such as a computer or wall adapter. A voltage regulator may be included to ensure a stable and appropriate voltage supply to the components. A power switch is incorporated to conveniently turn the board on or off.
