In previous sections, we used the GPIO output function for the LED lights. This time, we will finally need to use the GPIO input function. The human infrared sensing module is quite simple to use. After completing our experiment, we will combine it with the previous buzzer to create a simple human detection alarm. 1. … Read more
From the relevant information about the Raspberry Pi, we can see that there are two serial ports available: one is the hardware serial port (/dev/ttyAMA0), and the other is the mini serial port (/dev/ttyS0). The hardware serial port has a separate baud rate clock source, providing better performance and stability; the mini serial port has … Read more

The Raspberry Pi can be used to build a system from scratch or to play around with an existing system. For beginners, it is certainly easier to start with an existing system. Later on, one can compile the kernel, debug it, and build their own root filesystem (rootfs). I will also introduce some basic commands, … Read more
Click the above“Mechanical and Electronic Engineering Technology” to follow us Angular velocity sensors and acceleration sensors are common inertial sensors, often used to measure the rotation and linear motion of objects. The angular velocity sensor (Gyroscope) is used to measure the rotational speed or angular velocity of an object around three axes (X, Y, Z). … Read more
