Make Dumb Electronics Smart for $3
I Like To Make Stuff
Fun project for learning arduino. But I’d still just buy an ir/rf blaster that’s already “smart” for like 17 dollars that takes minimal space, requires minimal set up and can control multiple devices independently or as a group…..but what fun would that be. The tinkerer in me loves your vids though. So keep it up!
This is awesome, I have the same screen – never occurred to me to do this! I’m currently just taking the screws out of the remote (and saw the weird 12v battery 🙂 ) Now just need to follow your info.
For reference, I appreciate you don’t want to show code and small details (probably a lot get bored) I don’t, I’ve love to see you flesh out the idea … see you modifying the code … etc…
I use Home Assistant, this will end up attached to that as well. Thanks
Just for info – if you’re using an ESP32 and want ESPHome (because you can’t use Alexa for whatever reason)
Here’s code that will work in ESPHome and do exactly that in Home Assistant
# — PIN CONFIGURATION —
# We use standard Push-Pull mode (default).
# No ‘inverted: true’ because we want HIGH to be ON.
# Idle state will be LOW (Ground), which keeps the remote off.
output:
– platform: gpio
pin: 27
id: gpio_up
# inverted: false (Default)
– platform: gpio
pin: 26
id: gpio_stop
# inverted: false (Default)
– platform: gpio
pin: 25
id: gpio_down
# inverted: false (Default)
# Create “Button” entities in Home Assistant
button:
– platform: output
name: “Projector Screen Up”
output: gpio_up
duration: 500ms
icon: “mdi:arrow-up-box”
– platform: output
name: “Projector Screen Stop”
output: gpio_stop
duration: 500ms
icon: “mdi:stop-circle-outline”
– platform: output
name: “Projector Screen Down”
output: gpio_down
duration: 500ms
icon: “mdi:arrow-down-box”
A better idea then the limit switch for the screen would be a timed relay, triggered for the amount of time it takes for your screen to go down or up.
why on earth would you not mute the alexa part in the command? Love the video, but if this happens in all these videos i’m not subscribing. You have a lot of subscribers which will be annoyed by this.
