mr_bridge

This is a simple Motor/Relay pulse bridge that drives specified GPIO outputs for a specified period of time. Such implementation is actually used for controlling latching relays in Tuya switches. I also used it succesfully in Tuya valve.

Usage:

1. Add this external component to your yaml

external_components:
  - source: github://szupi-ipuzs/esphome-external-components
    components: mr_bridge

2. Add a switch and specify 2 gpio outputs as pin_forward and pin_reverse. You also need to define pulse_length which specifies the time (in ms) during which the outputs should be driven high. The allowed range is 10ms - 10000ms (10 seconds).
   Additional optional optimistic parameter (True/False) specifies if the switch state should be changed immediately (True) or only after the pulse is finished (False). The default is True.

switch:
  - platform: mr_bridge
    id: test_mrbridge_switch
    name: "Test M/R bridge"
    pin_forward: GPIO16
    pin_reverse: GPIO17
    pulse_length: 1000ms
    optimistic: False

It should be noted that I based this code greatly on OpenBeken's "bridge driver".
