Arduino UNO code for using an encoder with index can be: Encoder encoder = Encoder(2,3,600,A0); // A and B interrupt routine void doA(){encoder.handleA();} void doB(){encoder.handleB();} void doIndex(){encoder.handleIndex();} // software interrupt listener for index pin Pci...
Arduino Code – Rotary Encoder with InterruptIn the previous example code, we use the polling method, which continuously check the pin's state. This has two disadvantages:Waste Arduino resource Some counter may be missed if another code takes long time to excecute....

Just be aware of the role of thumb if you are using the encoders.STM32 devices Stm32 devices are probably the best choice for the FOC implementation MCU. They are very powerful and have many external interrupt pins. They don’t loose too much performance due to counting and have much ...
They are great fun and very useful and they even come with a couple of speed encoder disks (those little black circles full of holes). Problem is, no one tells you how to use them! Let’s resolve that and build a robot car with speed sensors. Along the way we’ll learn how to ...

The DC motor terminal pins are used to connect any DC motor to the Carrier board. There are 4 terminals, M1, M2, M3 & M4, marked with a +ve and -ve sign. You can connect 4 DC motors at the same time but there are only 2 encoder inputs. The polarity signs signifies the directio...
