Mission 3: Teach It A Word

Big Question

How can a robot show a message instead of only blinking a light?

Your Mission

Add a simple display output and make the robot brain say a short word. This turns the robot from a silent circuit into something that can give feedback.

Parts

• Bluepill on breadboard
• LED matrix or display module used by the lesson
• Jumper wires

Build

1. Add the display module shown in ModuLab.
2. Connect power and ground.
3. Connect the signal pins exactly as shown in the breadboard guide.
4. Check that no jumper wire is loose.

Connect

1. Plug in USB.
2. Press **Connect**.
3. Open the display or matrix panel.

Try It

Send a short word such as:

• HI
• OK
• GO

Keep the message short so it is easy to read.

Success Check

• The display lights up.
• Your word appears clearly.
• You can change the word and send it again.

Debug

If the display is blank:

• Check power and ground first.
• Check the signal wire.
• Try a very short message.
• Lower the brightness if the display looks strange.

Remix

Invent a robot name with four letters or fewer.

Make the display show the name when the robot wakes up.

Robot Brain Idea

A display is an output. Outputs let a robot show information to people, such as status, warnings, names, scores, and sensor readings.
