The rotary encoder is a rotation sensor whose direction and angle can be known. Similar in appearance to the potentiometer, the encoder has no limit stroke and instead of returning a resistance value, like the potentiometer, the encoder returns two digital signals...
The official Arduino Motor Shield is an expansion board for the Arduino UNO and Mega microcontrollers for DC and stepper motor control. We have seen how to drive a DC motor using an H-bridge which can require a lot of wiring when using the IC simply. For an embedded...
