| [bed-controller2.yaml](https://github.com/jdillenburg/esphome/blob/main/bed-controller2.yaml) | ESPHome code for bed angle controller |
| [components/adxl345](components/adxl345) | ADXL345 external component for measuring bed angle |
### Parts List
* ESP32-C3-DevKitM-1 board
* ADXL345 accelerometer - mounted under the bed frame
* 12V motor with motor controller (requires PWM inputs)
* LCD display with PCF8574 I2C adapter (16x2)
* WS2812 RGB LED for status indication
### Hook Up
1. Connect GPIO4 and GPIO5 to the motor controller's forward and reverse PWM inputs
2. Connect GPIO6 and GPIO7 to the motor controller's enable pins
3. Connect the ADXL345 accelerometer via I2C (SDA to GPIO0, SCL to GPIO1)
4. Connect the LCD display via I2C (address 0x27, same I2C bus as the accelerometer)
5. Connect assumes RGB LED connected to GPIO8 for status indication. My ESP32 had this built-in.
### Software Install
Add the ADXL345 external component to your configuration:
```yaml
external_components:
- source:
type: git
url: https://github.com/jdillenburg/esphome
ref: main
components: [ adxl345 ]
```
See the [ADXL345 component documentation](components/adxl345) for more details on configuration options.
