With this circuit you can drive a unipolar stepper motor. It operates in full step mode. The AVR attiny2313 micro controller controls the pulses for the stepper motor. The pulses are amplified by the ULN2003 driver. The driver accepts 5V inputs, the output for the driver is up to 30V so you can connect an …
Introduction The self adjusting window shade will automatically raise, lower, open, and close your blinds by itself. A computer terminal acts as a remote to broadcast instructions to the window shade via RF. These manual adjustments are stored into the microcontrollers system along with the rooms current ambient light and temperature settings. When these lighting …
Unipolar stepper motor driver can drive unipolar motor up to 3.5A and supply range 10 To 50V DC. The board has been designed using STK672-442AEN IC. The STK672-442AN is a hybrid IC for use as a unipolar, 2-phase stepper motor driver with PWM current control and Micro-stepping. Features Supply Up to 50V DC Input …
Further to my instructable 12V NE555 PWM Controller for Under $3 I have designed and built a simple and cheap DC Motor Direction Controller that can either be used with the PWM Controller, for speed control or by itself with a 12V power supply. I designed this DC Motor Direction Controller so that I could …
DRV10866 is a three phase, sensor less motor driver with integrated power MOSFETs with drive current capability up to 680 mA peak. DRV10866 is specifically designed for low noise and low external component count fan motor drive applications. DRV10866 has built in over-current protection with no external current sense resistor needed. The synchronous rectification mode …
