The KY-016 is capable of producing wide range of different colors by mixing blue, green and red lights. The RGB LED module will not require any limiting resistors. Those resistors are already integrated in the circuit, and so 5V can be directly used as power input.
Shift registers are integral components in digital electronics, enabling efficient data management and transfer. When working on Arduino projects, you may quickly run into the issue of not having enough output pins to control all your components. This is where SIPO (Serial-In, Parallel-Out) shift registers come into play. These devices allow you to manage multiple outputs with just a few pins on your Arduino, making them a powerful tool for more complex projects involving numerous LEDs, buttons or other peripherals. This article explores why shift registers are necessary, how they function, and their practical applications with Arduino.
In the world of do-it-yourself (DIY) projects, few activities match the practicality of constructing your own Arduino-powered automatic watering system. Imagine a setup where technology integrates effortlessly with nature, allowing you to take control of your plant care routine. We'll break down the fundamental components of this project, highlighting the vital role of the DS1302 timekeeping module and Arduino-compatible pumps. Get ready for a hands-on approach that not only enhances your technical skills but also transforms the way you care for your plants, whether they are in the corners of your home or under the open sky.
Wireless communication implies having a transmitter, in our case the joystick, and a receiver. We must build a simple circuit with NRF24L01 wiring that will act as listener for our joystick. The NRF24L01 module strictly needs 3.3V but the logic pins are 5V tolerant. That why we recommend to use the NRF24L01 adapter which acts as regulator, keep the voltage stable, apply filtering and reduce noises.
Touch sensor (also known as touch button) is widely used to control devices. It detects touch, force or pressure on its surface changing the logic state of the circuit. Actually, it works in very similar way as to buttons. Checkout the wiring and Arduino code implementation to track the current state and the state changes.
Let's speak now about switch buttons, the wiring and how to implement the code for this circuit elements in Arduino. Switch buttons connect two points in a circuit when you press them and maintain the state without the need to keep the button pressed. That means that logic state of the circuit change every time you press the button.
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow and adjust signal levels among other uses. Resistance is measured in Ohm with a sign of Ω.
A microcontroller (e.g. Arduino) utilizes I/O signals for communication with external hardware devices, where the most commonly known being GPIO. As a reminder, digital logic circuits have three logic states: high, low and floating (or high impedance). When there’s nothing connected to your GPIO pins, your program will read a floating impedance state, which we do not want. To achieve either high or low states, we’ll have to implement pull-up or pull-down resistors in our digital circuit.
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language and the Arduino Software (IDE).
Radio control cars are small vehicles powered by electric or gas motors that can be remotely controlled by a transmitter. The transmitter sends signals to a receiver on the car, allowing the operator to control the car's speed, direction, and steering. Radio control cars are available in a variety of sizes, from miniature models that can fit in the palm of your hand to large off-road vehicles that can climb over rough terrain.
Arduino, a familiar name among DIY enthusiasts and electronics hobbyists, owes much of its popularity to its user-friendly Integrated Development Environment (IDE). One of the most invaluable tools within the Arduino IDE is the Serial Monitor. This feature plays a pivotal role in facilitating communication between your Arduino board and your computer, allowing you to monitor and control your projects in real-time. In this article, we'll explore the practical aspects of using the Arduino IDE and Serial Monitor, shedding light on how they can be harnessed for effective data exchange.
