Simple alarm demo
Sounds a buzzer when a threshold is crossed in a supervised demo area.
What you build in this project
Simple alarm demo is one focused build from the Fire Detection & Sensor Learning Kit. It uses the parts listed below to make a working electronics example, then you can combine it with the other projects in the kit.
Sounds a buzzer when a threshold is crossed in a supervised demo area.
Parts used
flame sensor, Arduino UNO, active buzzer
What to check
Wire the parts, upload the sketch from the kit page, then test this project by watching the Serial Monitor or the output behavior.
What you learn
You learn how the controller reads real sensor signals, makes a decision in code, and turns that result into a useful output.
What this project uses
Every item is in the kit — nothing extra to buy.

More from this kit
Flame direction indicator
Shows which sensor channel sees the strongest IR source so students can learn directional sensing.
Sensor threshold lab
Logs digital channel changes while students compare distance, angle, and ambient light effects.
