Overview LEDs can uniquely control the amount of three primary colors (red, green, and blue) to create a desired color. Thanks to this feature, they are now an attractive and practical component in Electronics and Lighting industry. An RGB LED has one common pin as well as three pins for red, green, and blue colors. We can combine these primary colors to create countless colors by controlling these pins with a PWM pulse signal. (The number of colors depends on the resolution of the generated PWM signal)...

Overview A potentiometer is a device that can change its resistance by moving a contact along a fixed resistor. It has three terminals: one connected to each end of the resistor and one connected to the movable contact. By adjusting the position of the contact, the potentiometer can divide the input voltage into different output voltages [Read more in Wikipedia]. Potentiometers work by creating a voltage drop across the resistor that is proportional to its length. For example, if the input voltage is 10...

GY-25 Module Features The GY-25 sensor module is a high-resolution 3-axis sensor based on the MPU6050 sensor. It includes a 3-axis gyroscope and a 3-axis accelerometer, all in the MPU6050 sensor chip. The GY-25 module also has a microcontroller called the 32F030F4P6. Its role is to process and convert data from the MPU6050 sensor to obtain the angle value. The microcontroller and Arduino board communicate with the GY-25 module through the UART interface. In addition, the GY-25 module has an I2C interface fo...
