roller shutter

[Reza]

hi
this is a roller shutter sketch that i wrote a simple sketch

#define MY_DEBUG
#define MY_RADIO_NRF24
#define MY_RF24_CHANNEL 0
#define MY_REPEATER_FEATURE
#include MY_NODE_ID 20

#include <SPI.h>
#include <MySensors.h>

#define RELAY_1  3
#define RELAY_2  4



void before() {
  int sensor = 1;
  pinMode(RELAY_1, OUTPUT);
  pinMode(RELAY_2, OUTPUT);
  digitalWrite(RELAY_1,HIGH);
  digitalWrite(RELAY_2,HIGH);

}



void setup() {
}
void presentation()
{
  sendSketchInfo("Roller shutter", "1.0");
  int sensor = 1 ;
  present(sensor, S_COVER);
}

void loop() {
}
void receive(const MyMessage &message) {
  if (message.type == V_UP) {
    digitalWrite(RELAY_1, HIGH);
    delay(500);
    digitalWrite(RELAY_2, LOW);
  }
  if (message.type == V_STOP ) {
    digitalWrite(RELAY_1, HIGH);
    delay(500);
    digitalWrite(RELAY_2, HIGH);
  }
  if (message.type == V_DOWN) {
    digitalWrite(RELAY_2, HIGH);
    delay(500);
    digitalWrite(RELAY_1, LOW);
  }
}

Nice, I was wondering about something like this but couldn't think how you'd handle limits? Unless the motor handles them..

there is a 2channel relay and motor left round wire is connect to one relay and motor right round wire is connect to other channel.
here HIGH = off and LOW = on
for left round (right round is off and left round is on)
for right round (left round is off and right round is on)
for stop both is off

@Reza Oh I understand that but with stop command you could quite quickly have the shutter fully open but the motors still running. Right?
