LED proximity bar
Lights red/yellow/green indicators based on measured distance ranges after calibration.
What you build in this project
LED proximity bar is one focused build from the Distance & Parking Sensor 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.
Lights red/yellow/green indicators based on measured distance ranges after calibration.
Parts used
HC-SR04, Arduino UNO, LEDs, resistor pack
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.
Distance & Parking Sensor Kit
All 9 parts in one box, with this project and 2 more to build from them.
Need only these parts? Order them loose · from AED 91.82
One of each part. Packs (resistor assortment, jumper wires) already hold more than a single build needs. LEDs: included in the kit, ask us for it loose. Delivery is free on orders AED 150.00+.
More from this kit
Parking distance beeper
Reads distance and increases beep frequency as an object gets closer. For learning only, not a vehicle safety device.
OLED distance meter
Shows distance in centimeters on a small display once I2C wiring and library compatibility are tested.
