- Use handle + callback to make your robot respond instantly to remote commands.
- Use key names like
"forward","left","stop"to control movement. - Use conditions to match commands and trigger actions — like turning on a motor or light.
- Use println to see what’s happening — it’s your robot’s voice for debugging.
- Always check connection status before reacting — no Bluetooth, no control!
