DIY Robotic Arm with Brushless DC Motors and Raspberry Pi JesseDarr’s new project is different from the usual DIY robotics project. He has made a robotic arm called dARM. It is a robotic arm with 6 degrees of freedom, and most of the parts are 3D printed. He has used brushless DC motors for its working rather than servo motors. These are the kind of motors you would usually find in more advanced machines, and they help the arm move more smoothly and… |

A Simple 555 Timer based Buck Regulator for LED Dimmers and DC Motor Speed Control In this article, we will make a buck converter using 555 timer IC and a IRFZ44N N channel MOSFET and use it as LED dimmer circuit or as a motor speed controller circuit. This circuit is basically a simple power electronics DC-DC Buck converter which can be used to step down voltage, its efficiency results in better battery life due to reduced heat generation making it a… |

Simple H-Bridge Motor Driver Circuit using MOSFET At the outset, driving a motor might seem like an easy task – just hook the motor up to the appropriate voltage rail and it will start rotating. But this is not the perfect way to drive a motor, especially when there are other components involved in the circuit. Here, we will discuss one of the most commonly used and efficient ways to drive DC motors, the H-Bridge circuit.… |
