Today, we will use the Arduino development board to control a servo motor, creating a simple 2-degree-of-freedom gimbal. Based on its rotation characteristics, the gimbal can be divided into a horizontal gimbal that can only rotate left and right, and an omnidirectional gimbal that can rotate both left and right as well as up and … Read more
Do you want to play with circuits but don’t know how to design a PCB? You can! Before PCBs existed, components were connected directly (as imagined by Teacher Su). In fact, even when we have PCB design issues that require rework, we often use various jumper wires to make our circuits work. So, even if … Read more
