PymateIO-remote-control

Abstract

The remote control is the most widespread usage in automation.

Click once and lights turn on, click again then the lights shut-off.

Wiring

Here a typical wiring;

• Push Buttons are connected to IN3 (connected in parallels)
• Stairs lights are controlled by OUT5 (via a relay)

Script

Here an commented example of main.py script that can be used with PymateIO Core.

The TimeoutTimer class is used to start a Timeout of 2 seconds when the button is pressed.

Any additional button press will be ignored within that period of time.

Once the 2 seconds expired, a new button press will be accepted.

from machine import Pin
from pymate import TimeoutTimer
from pymate.pymateio import PymateIO

FORBID_SEC = 2

button = PymateIO( "In3", Pin.IN )
relay = PymateIO( "Out5", Pin.OUT )
relay.write( 0 )

# Start a timer that expires immediately for
# coding convenience
t = TimeoutTimer(0.1) 

while True:
	# Button Pressed and
	# Outside of forbidden period
	if button.read() and t.expired:
		# Invert Output State
		relay.write( not(relay.read()) )
		# Restart a new forbidden period
		t.set( FORBID_SEC )
