Suggested Project: LED Traffic Light
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.
What you build in this project
Suggested Project: LED Traffic Light 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.
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.
Parts used
UNO R3, full-size breadboard, jumper wires, red/yellow/green LEDs, resistor assortment
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.
Arduino UNO Sensor & Output Starter Kit - LEDs, Buzzer, Servo, Ultrasonic & LCD
All 10 parts in one box, with this project and 6 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. red/yellow/green LEDs: included in the kit, ask us for it loose. Delivery is free on orders AED 150.00+.

Suggested Project: Buzzer Alert Patterns
Create simple warning patterns and learn active-high versus active-low control. Confirm the module logic before adapting the main sketch.
Suggested Project: Analog LED Dimmer
Read the potentiometer on an analog input and map the result to LED brightness on a PWM-capable output. Select a pin that does not conflict with any other parts retained…
Main Project: Parking Assistant & Sensor Dashboard
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…
