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.
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.
Laser modules emit highly focused beams of light, making them ideal for a wide range of applications. One of the key aspects of a laser module is its power output, typically measured in milliwatts (mW). Arduino compatible laser modules typically have a power output within the lower range ensuring safety and compatibility with the microcontroller board. It's important to note that modules require safety precautions due to their increased risk of eye damage and potential fire hazards for higher-power lasers.
In the fascinating world of Arduino and microcontrollers, keeping time is key. You might need to build a digital clock, a timer, or something more complex like an automated plant watering system. That's where the DS1302 module steps in. It's a handy little device that can help you keep time accurately in your Arduino projects. In this article, we'll take a closer look at the DS1302 module, understand how it works, and explore its applications.
Precision monitoring of atmospheric conditions becomes a reality with the GY-65 module based on BMP085 sensor. Armed with the ability to measure temperature, pressure, and altitude, the GY-65 module opens up a world of possibilities for weather stations, altitude tracking devices, and other projects requiring accurate environmental data. In this article, we delve into the capabilities of the module, examining its features, connectivity with Arduino.
Transistors are semiconductor devices that regulate the flow of electrical current within a circuit. Their invention in the mid-20th century marked a pivotal moment in electronics. Semiconductors, typically made of silicon or germanium, form the basis of transistors, granting them the ability to switch and amplify electrical signals. These devices have revolutionized the world of electronics, making way for the digital age by enabling the miniaturization of complex circuits and facilitating the rapid advancement of technology.
The GY-68 module, also known as the BMP180 module, is a popular sensor module used for measuring atmospheric pressure, temperature, and altitude. It features a highly precise digital barometric pressure sensor that can be easily integrated with an Arduino board. In this tutorial, we will guide you through the process of connecting the GY-68 module to an Arduino, enabling you to gather accurate environmental data for your projects. So, let's get started!
Arduino microcontrollers are the heart of countless DIY projects, from robots to automated systems. To bring these projects to life, you often need to interface them with motors. In this guide, we'll walk you through the essential steps of connecting a motor to an Arduino using a separate power supply while ensuring control with precision using an NPN transistor. This approach allows you to harness the full potential of your motorized creations without overloading your Arduino.
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.
