Pulse Width Modulation (PWM) is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between ON and OFF. If you repeat this on/off pattern fast enough with a LED for example, the result is as if the signal is a steady voltage between 0 and VCC controlling the brightness of the LED.
A potentiometer is a simple knob that provides a variable resistance, which we can read into the Arduino board as an analog value. They can be attuned from zero ohms to whatever maximum resistance that is specific to it. For example, a potentiometer of 10 kΩ can be adjusted from 0 Ω to its maximum of 10 kΩ.
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.
The integration of components with Arduino opens a world of possibilities. One often overlooked but incredibly useful component is the vibration motor. Vibration motors are compact, motorized devices designed to generate vibrations. This device, often found in smartphones and game controllers, can add a tactile dimension to your projects, providing physical feedback that enhances user experience. In this article, we'll explore the basics of vibration motors and explore into how you can effortlessly connect them to Arduino for a wide range of applications.
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!
The RF-Nano module is a compact, affordable module that combines an NRF24L01 wireless transceiver with an Arduino-compatible microcontroller. Using the NRF24L01 protocol, the RF-Nano operates on the 2.4 GHz band, making it a practical choice for creating simple, low-power wireless networks. This module is popular among hobbyists and engineers for tasks like home automation, remote control applications, and IoT sensor networks. It’s especially suited for applications where simple, secure data sharing between sensors or remote control devices is required and where a compact, low-cost solution is preferred.
In the world of DIY electronics, Arduino stands as a go-to tool for creators and hobbyists. Today, we're exploring the integration of a 4x4 membrane keypad module with an Arduino, a combination that introduces an interactive layer to your electronic projects.
Controlling devices over a distance opens lots of possibilities. Our Arduino roadmap contains many projects that must be controlled remotely and sometimes on a long-distance. Of course, it can be done with a PC but our experience has shown that it becomes complicated when you need long way, portable and rapid communications. Our solution was designing a multi-functional remote controller, we have called it AirControl. Aware of the needs it will have 4 push buttons, 2 switch buttons, 2 potentiometers and two analog modules. Additionally, each analog joystick module has integrated push button.
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.
The physical assembly of the car has been completed with all the components properly installed and ready for use. The next steps involve reprogramming the Arduino Nano with the appropriate software to enable all the features, including pairing the car with the AirControl joystick via the NRF24L01 module.
