What is a Stepper Motor? A stepper motor is a type of motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. For a stepper motor, each input pulse signal causes the rotor to rotate by a certain angle or take a step forward. The output angular displacement or linear displacement is … Read more
Before the invention of the breadboard (in the 1960s), you had to use a technique called wire wrapping to build circuits. The wire wrap connects the circuit by linking conductive posts to a perforated board and winding wires around them. As shown in the image below, the circuit can be quite complex. The circuit board … Read more
