|

|
||||
## Usage
|
||||
|
||||
Run the app, and ensure you're not connected to your watch via Bluetooth
|
||||
(a warning will pop up if so).
|
||||
Run the app, then choose the type of controls you want and ensure you're not connected
|
||||
to your watch via Bluetooth (a warning will pop up if so).
|
||||
|
||||
Linear mode controls A/B axes individually, and allows you to vary the speed of the
|
||||
motors based on the distance you drag from the centre. Other modes just use on/off
|
||||
buttons.
|
||||
|
||||
| Mode | up | down | left | right |
|
||||
|------------|------|------|------|-------|
|
||||
| **Linear** | +A | -A | -B | +B |
|
||||
| **Normal** | +A | -A | -B | +B |
|
||||
| **Tank** | -A+B | +A-B | +A+B | -A-B |
|
||||
| **Merged** | -A-B | +A+B | +A-B | -A+B |
|
||||
|
||||
In all cases pressing the C/D buttons will turn on C/D outputs
|
||||
|
||||
Now press the arrow keys on the screen to control the robot.
