The 5v relay module with i2c control requires only 2 pin sda and scl data to control 8 relay.
It can be connected up to 128-256 channel relay by changing the i2c address of each i2c module.
Pcf8574t waveshare controller
Work voltage: 5v dc (min 1a)
Interface: I2c (sda scl)
Arduino library: Pcf8574.h
Take a library folder that pcf8574 only (cut to root folder library arduino)
Coding example:
#Inclusive
#Including "pcf8574.h"
Pcf8574 rjrelay;
#Define on 0 / / low active relay
#Define off 1.
#Define relay 8 / 8 channel number relay
Setup void () (
Serial.begin (115200);
Rjrelay.begin (0x20);
For (int i = 0; i < 8; i + +) (
Rjrelay.pinmode (i, output);
}
}
Void loop () (
For (int i = 0; i < 8; i + +) (
Rjrelay.digitalwrite (i, on);
Delay (300);)
For (int i = 0; i < 8; i + +) (
Rjrelay.digitalwrite (i, off);
Delay (300);)
For (int i = 0; i < 8; i + +) (
Delay (300);)
For (int a = 0; a < 5; a + +) (
For (int i = 0; i < 9; i + +) (
If (i > 0) (rjrelay.digitalwrite (i, on);
Rjrelay.digitalwrite (i-1, off);)
Else (rjrelay.digitalwrite (i, on);)
Delay (100);)
