Measure distance and print centimetre readings in Serial Monitor. Test with a flat target and reuse the main build's D8/D9 sensor wiring.
Suggested Project: Ultrasonic Distance Meter is one focused build from the Arduino UNO Sensor & Output Starter Kit - LEDs, Buzzer, Servo, Ultrasonic & LCD. It uses the parts listed below to make a working electronics example, then you can combine it with the other projects in the kit.
Measure distance and print centimetre readings in Serial Monitor. Test with a flat target and reuse the main build's D8/D9 sensor wiring.
UNO R3, HC-SR04, breadboard, jumper wires
Wire the parts, upload the sketch from the kit page, then test this project by watching the Serial Monitor or the output behavior.
You learn how the controller reads real sensor signals, makes a decision in code, and turns that result into a useful output.
Every item is in the kit — nothing extra to buy.
All 10 parts in one box, with this project and 6 more to build from them.
One of each part. Packs (resistor assortment, jumper wires) already hold more than a single build needs. Delivery is free on orders AED 150.00+.
Follow the complete guide, wiring table, test sequence, and supplied firmware below. The HC-SR04 measures distance; LEDs show far, approaching, and near zones; the buzze…
Explore digital outputs and timing by sequencing three protected LEDs. This is a suggested extension; choose and document a separate pin plan before building it.
Create simple warning patterns and learn active-high versus active-low control. Confirm the module logic before adapting the main sketch.
