Relay Pattern Sample

This sample demonstrates controlling all the relays with one command.

To run the sample:

1. Download the sample code from https://github.com/Turta-io/RelayHAT2/blob/master/Samples/Python/Relay_Pattern.py

2. Copy the sample code to a folder on the Raspberry Pi.

3. Open terminal, and then go to the folder you copied the sample.

4. Run the sample with the following command:

python3 Relay_Pattern.py

Sample Code

Relay_Pattern.py

#!/usr/bin/env python3

#This sample demonstrates controlling all the relays with one command.
#Install Relay HAT 2 library with "pip3 install turta-relayhat2"

from time import sleep
from turta_relayhat2 import Turta_Relay

#Initialize
relay = Turta_Relay.RelayController()

try:
    while 1:
        #Pattern 1
        relay.write_once(0b10101)
        print("Relay Pattern...: 10101")
        sleep(2.0)

        #Pattern 2
        relay.write_once(0b01010)
        print("Relay Pattern...: 01010")
        sleep(2.0)

        #Pattern 3
        relay.write_once(0b00100)
        print("Relay Pattern...: 00100")
        sleep(2.0)

except KeyboardInterrupt:
    print('Bye.')

Result

When you run the sample, the relay states are changed every two seconds. The example output should be like this:

Relay Pattern...: 10101
Relay Pattern...: 01010
Relay Pattern...: 00100
