PWM Fan Controller schematic
The heart of the PWM Fan Controller is a PIC 12F675 microcontroller. This microcontroller is reading the analog output of a LM35 temperature sensor using a ADC (analog to digital converter). The resulting digital value is converted to a temperature...
PWM Speed Rotation Forard-Reverse and Regenerative Braking
This circuit is a PWM speed control circuit for a DC motor rotation. It supports forward and reverse rotation as well as regenerative braking functions. The circuit utilizes a PWM signal to control the speed of a 12V DC motor...
Big Trak Motor Driver Schematic
Schematic of Big Trak's motor driver circuit. The toy includes 9112 and 9113 transistors (and sometimes 2N6715) because the 75494 chip cannot supply enough current to run the Big Trak's motors by itself.
The motor driver circuit for the Big Trak...
Pwm Motor-Drive Circuit Circuit
This circuit will drive a small DC motor over a wide range of speeds without stalling by controlling the duty cycle of the motor, rather than the supply voltage.
