Relay Toggle Sample

This sample demonstrates toggling the relays.

To run the sample:

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