Using a Joystick with Esphome

ESPHome
1

Has anyone been able to use one of these joysticks with Esphome?

That is ridiculously cheap isn’t it?

The docs says it acts as two analog readings (for x and y) and a switch (for press). You’d need two ADC pins, so a ESP32 should work best.

You’ll also need to adjust the voltage from 5v down to 1.1v with voltage divider resistors.

Has anyone got a simple example for home assistant esphome 32 board

Ie moving a dot on screen in graph box or anything for me to get a simple starter project
Not very complicated
Moving in a box google map even for location with stick example anything easy to do with
Homeassistant and esphome thanks brian

The following works for me using this joystick: Arduino Compatible X and Y Axis Joystick Module | Jaycar Electronics New Zealand

I am powering this off the ESP32 3.3v, so no other voltage changes are needed, as each axis becomes 0-3.3v.

sensor:
  - platform: adc
    id: joystick_x  
    name: "Joystick X axis"  
    pin: GPIO33
    internal: True
    attenuation: auto
    update_interval: 500ms

  - platform: adc
    id: joystick_y  
    name: "Joystick Y axis"  
    pin: GPIO35
    internal: True
    attenuation: 11db
    update_interval: 500ms
binary_sensor:
  # https://home-assistant-guide.com/guide/how-to-use-a-physical-switch-or-button-in-esphome-with-gpio-binary-sensor/
  - platform: gpio
    id: joystick_click
    pin:
      number: GPIO32
      mode: INPUT_PULLUP
      inverted: True
    name: "Joystick click"
    internal: True
display:
 ...
          if (id(joystick_x).has_state()) {
            it.printf(127, 70, id(roboto_10), colour_green, TextAlign::BASELINE_RIGHT , "JSX %.1f °", id(joystick_x).state);  
          }
          else {
            it.print(127, 70, id(roboto_10), colour_red, TextAlign::TOP_RIGHT ,"NJSX");  
          }

          if (id(joystick_y).has_state()) {
            it.printf(127, 80, id(roboto_10), colour_green, TextAlign::BASELINE_RIGHT , "JSY %.1f °", id(joystick_y).state);  
          }
          else {
            it.print(127, 80, id(roboto_10), colour_red, TextAlign::TOP_RIGHT ,"NJSY");  
          }
