🎉 The MakerBuddy Expo
Learning Objective
Communicate your invention confidently to a live audience. Master the Elevator Pitch formula, deliver a live demonstration of your MakerBuddy, and celebrate your journey from beginner to IoT Innovator!
Theory: The Elevator Pitch
Tell the whole story: the problem, your build, proof that it works, and the benefit.
You Have 30 Seconds. Go!
An Elevator Pitch is a short, clear speech about your idea. It lasts about as long as an elevator ride: around 30 seconds. It keeps you simple, direct and focused on the benefit, not the technical details.
The Perfect Pitch Formula
🙋 "Hi, my name is [Your Name].
😟 I noticed that [Target User] has a problem with [Problem].
🔧 So I built [Project Name] using my MakerBuddy kit.
🤖 It uses a [Sensor Name] to detect [Event / Condition], and then it automatically [Action] using the Rule Engine.
✅ This solves the problem because [Benefit]."
Example Pitch
"Hi, my name is Sara. I noticed that my family has a problem with forgetting to water our plants when we go on vacation. So I built the PlantGuard using my MakerBuddy. It uses a Soil Moisture sensor to detect when the soil gets too dry, and then it automatically turns on the Relay (water pump) and flashes the LED using the Rule Engine. This solves the problem because the plant waters itself, so no one has to remember!"
For Teachers
Give students 10 minutes to write and rehearse their pitch with the formula. Let pairs practice on each other first to calm nerves. Judges are impressed by confidence and clarity, not technical jargon.
Activity: Setting Up Your Expo Station
It's showtime! Set up your station like this:
- Clear Your Desk: Put the MakerBuddy in the center. Tidy the cables so visitors can see every part.
- Place Your Info Card: Write your project name, your name and one sentence on what it does. Put it next to the MakerBuddy.
- Power Up: Connect the USB cable and give the board about 30 seconds to join the Wi-Fi network it was set up on in Week 3, then press 🔌 Connect in the WebApp. Check that every rule you need shows ▶️ Running or 👁️ Monitoring, not 🛑 Manually Stopped (or ⏸️ Stopped on a Forever or Timer rule). If one does, press ▶️ on that rule's row to start it. A No Loop rule that has already run shows ⏸️ Stopped, and that is fine. No Wi-Fi in the Expo room? Your saved rules still run on their own, but you can't open the dashboard. Hold the push button for more than 10 seconds (to set up a new network) only if your teacher says so.
- Do a Dry Run: Trigger your main rule yourself. Does everything work? If not, use the 4-step troubleshooting process from Week 31 to fix it fast.
- Stand Ready: Stand by your project. When a visitor comes over, give your Elevator Pitch right away, then show the live demo.
Be Proud
You built something real! Own it.
Start Talking
Use your Elevator Pitch formula. Keep it simple and clear.
Demonstrate
Show it live! Trigger the sensor and let your MakerBuddy do the talking.

Look How Far You've Come!
This year you learned to think like an engineer. Here is what you can now do:
Algorithms
Step-by-step instructions a computer can follow.
Loop Modes
All four: No Loop, Forever, Timer (an interval in hours, minutes and seconds) and Condition.
Sensors
Temperature, Humidity, Light, Gas, Distance, Motion, Soil Moisture, and more.
Actuators
LED On / LED Off, RGB LED, Buzzer On / Buzzer Off, Relay On/Off, Servo, LCD.
Condition Logic
Operators (>, <, >=, <=, ==), AND/OR ranges and two-sensor rules, thresholds, and Threshold Windows to prevent jitter.
Multi-Step Rules
Several actions in a row, with exact ms delays between them.
State Diagrams
Planning a system before you write any rules.
Debugging
A 4-step process: Power → Sensors → Outputs → Logic.
Congratulations, IoT Innovator!
Learning Support
Use this quick guide to help every learner understand, practice and explain The MakerBuddy Expo.
For students
Try it in three steps
- Say it: explain the main idea in one simple sentence.
- Show it: Present your working prototype to the class. Explain your rule engine logic.
- Stretch it: Demo your project live under at least three conditions (below, inside and above your thresholds) and explain what each rule did.
Checkpoint: What was your input, what decision or process happened, and what was the output?
For teachers & parents
Coach without taking over
- Before: ask the learner to predict what will happen and why.
- During: use prompts such as “What changed?” and “What could you test next?” instead of giving the answer.
- After: ask for a 30-second explanation, one piece of evidence and one improvement.
Look for: safe handling, correct vocabulary, a result the learner can demonstrate, and an explanation in their own words.
