Introduction

This adapter is especially designed for DFRobot 12V DC Motors. This adapter comprises an external pull-up resistor, which raises the output voltage when the transistor is turned off. This board has two build-in pull-up resistors.

Specification
• Compatible with open collector output encoder
• Size:31x24mm
• Hall Sensor 5v

Encoder Sample Code
/* Pay attention to the interrupt pin,please check which microcontroller you use */ //The sample code for driving one way motor encoder
const byte encoder0pinA = 2;//A pin -> the interrupt pin 2 const byte encoder0pinB = 4;//B pin -> the digital pin 4 byte encoder0PinALast int duration;//the number of the pulses boolean Direction;//the rotation direction
void setup

Serial.begin 57600 ;//Initialize the serial port EncoderInit ;//Initialize the module
void loop

Serial.print "Pulse:" Serial.println duration = 0 delay 100 ;
void EncoderInit

Direction = true;//default -> Forward pinMode encoder0pinB,INPUT attachInterrupt 0, wheelSpeed, CHANGE ;//int.0
void wheelSpeed
int Lstate = digitalRead encoder0pinA if encoder0PinALast == LOW && Lstate==HIGH
int val = digitalRead encoder0pinB ;
if val == LOW && Direction

Direction = false //Reverse else if val == HIGH && !Direction

Direction = true //Forward encoder0PinALast = Lstate if !Direction duration++ else duration--;
