1. Forward Button:

   • Press: "f"
   • Release: "F"

2. Backward Button:

   • Press: "b"
   • Release: "B"

3. Left Button:

   • Press: "l"
   • Release: "L"

4. Right Button:

   • Press: "r"
   • Release: "R"

5. Object Detection Trigger Button:

   • Press: "o"
   • Release: ""

6. Wall Follower Trigger Button:

   • Press: "w"
   • Release: ""

7. Speed Control Slider:

   • Min: 0
