10. Tasks

Before doing the tasks, please make sure that you can control the robot using IR Remote. You should also know how to use Serial commands using Arduino Serial Monitor.

You might need to 3D print some parts to mount your sensors.

Note

These tasks will use Arduino UNO are Higher level controller and the Bittle board as low level controller. You must upload all your codes only to Arduino UNO. All sensors and actuators must be connected to Arduino UNO and not directly to Bittle board.

Note

Use Serial baud rate as 15200 for communicating with Bittle Board.

Hint

You can use SoftwareSerial for the following tasks. Look about this before using.

Warning

Use develop branch for all initial codes. Create other branches according to the requirements.

When everything is ready before submission, merge the code to main branch.

WHEN MERGING develop TO main DE-SELECT “Delete source branch when merge request is accepted.” OPTION.

10.1. Connections

Connect your Bittle with Arduino UNO / ESP32 CAM using TX and RX pins. The connection should be as below:

Arduino UNO	Bittle Board
TX	Rx
GND	GND
VIN	5V

Warning

When uploading code, you might have to remove the TX and RX pins from Arduino UNO board as they are connected to the USB programmer.

Hint

You can also use Software Serial to virtually create TX and RX on any available digital pin on UNO board.

10.2. Task 1

Make Bittle move straight for some distance, perform a skill, turn around and return back to the start point. The command must start from Node-RED.

Fig. 10.9 Task: Follow straight line

10.3. Task 2

Bittle follows a line. The line will have curves, and will not be always straight.

Using ESP32CAM , you must make bittle follow a line. The line will be White line on a Black (dark) floor.
