This the DC motor controls circuit with a signal MCU. By can control DC Motor 24V can fine the speed of motor with pulse and timer (MCU). This circuit composes transistor and power mosfet (MBR1045). Then motor driver has been verying and still have the circuit changes the direction of motor Reverse [...]

This is an actual reverse engineered circuit diagram of the one transistor circuit most commonly used to drive Permanent Magnet DC motors in childrens’ toys. This type of circuit almost always uses the 625mW version of the ubiquitous 8050 or 8550 transistor. It is vital to note that there are two different varieties of each [...]

Physical motion of some form helps differentiate a robot from a computer. It would be nice if a motor could be attached directly to a chip that controlled the movement. But, most chips can’t pass enough current or voltage to spin a motor. Also, motors tend to be electrically noisy (spikes) and can slam power [...]
