Layout Introduction
Function about every component：
- Infrared transmitter：transmit the infrared signal, the signal can be used for detecting obstacles
- Infrared receiver：receive infrared signal, the signal can be used for obstacle avoidance
- Photosensitive diode：sensitive with the light, so it can help you get some information about the light
- Button：can be programmed for your idea
- RGB LED：you can change its color use your code, it can show as an alarm and other things you want
- USB port：download your code and let your robot talk to your computer
- Buzzer（passive）：be an alarm bell or sing a simple song
- Controller：runs your code
- Motor：can be controlled to run forward or backward, so that the car can turn left or right freely
- Reset button；Reset the robot, the program in the robot will runs again from its initiation
- Power switch：power switch of the robot
- Power port：power provided from this port
- Charge port: if your batteries can be charged， you can charge them from this port thus they can be hold in the car
- Infrared line-follow sensor: can be used for detecting for white or black lines
