Relay Toggle Sample

This sample demonstrates toggling the relays.

To run the sample:
Download the sample code from https://github.com/Turta-io/RelayHAT2/blob/master/Samples/Python/Relay_Toggle.py​
Copy the sample code to a folder on the Raspberry Pi.
Open terminal, and then go to the folder you copied the sample.
Run the sample with the following command:
python3 Relay_Toggle.py
Sample Code
Relay_Toggle.py
#!/usr/bin/env python3
​
#This sample demonstrates toggling the relays.
#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:
        #Toggle relays 1 to 5
        for x in range(1, 6):
            print("Toggling relay", x)
            relay.toggle(x)
            sleep(2.0)
​
        #Toggle all relays
        relay.toggle_all()
        print("Toggling all relays")
        sleep(2.0)
​
except KeyboardInterrupt:
    print('Bye.')
Result
When you run the sample, the relays invert their states sequentially. The application also writes the relay states to the terminal. The example output should be like this:
Toggling relay 1
Toggling relay 2
Toggling relay 3
Toggling relay 4
Toggling relay 5
Toggling all relays
To stop the Python script, just press CTRL + C.
