# Haptic Feedback

## Haptic feedback rules.mk options

The following options are currently available for haptic feedback in `rule.mk`:

`HAPTIC_ENABLE += DRV2605L`

`HAPTIC_ENABLE += SOLENOID`

### Solenoids

First you will need a build a circuit to drive the solenoid through a mosfet as most MCU will not be able to provide the current needed to drive the coil in the solenoid.

[Wiring diagram provided by Adafruit](https://playground.arduino.cc/uploads/Learning/solenoid_driver.pdf)

Select a pin that has PWM for the signal pin

```
#define SOLENOID_PIN *pin*
```

Beware that some pins may be powered during bootloader (ie. A13 on the STM32F303 chip) and will result in the solenoid kept in the on state through the whole flashing process. This may overheat and damage the solenoid. If you find that the pin the solenoid is connected to is triggering the solenoid during bootloader/DFU, select another pin.
