While there are a couple of open-source brushless drivers already available, [neuromancer2701] created his own brushless motor controller on an Arduino ... than hall effect sensors mounted on ...

Red/VCC (5-24V DC Input), Black/GND (0V) and Yellow/OUT (Pulse Output). By counting the pulses from the output of the sensor, we can easily calculate the water flow rate (in litre/hour – L/hr) using a ...

Driving a brushless DC (gimbal) motor can be a pain in the transistors. [Ignas] has written up a nice article not only explaining how to do just this with an Arduino, but also explaining a little ...

Recommended working voltage of the module is 4.5 to 5.5 volt dc. Note that one side of the optical sensor holds s ... module was connected to an Arduino board and measured the rotation per minute (rpm ...

It features two ultrasonic sensors mounted on your ... it then sends a signal to the Arduino UNO, which, in turn, triggers the motor driver (connected to two DC motors) to move the box either ...
