This is a mini-traffic light, with 5mm LEDs, and is suitable for the production of a traffic light system model. It is small in size, simple to wire, and easy to demonstrate how a traffic robot works. It can be connected to PWM to control the brightness of the LED.
These Mini Traffic Lights can be used with a microcontroller. By using a microcontroller like the Arduino Uno, you can simulate four junctions by using three more of these Mini Traffic Lights.
Mini Traffic Light Specification:
- Number of lights: 3
- Light color: red, yellow, and green
- Active level: high level
- Operating voltage: 5V / 3.3V
- Operating current: When you use 5V high-level output, the red light is 13mA, yellow light 13mA, and green light 25mA.
- Can be connected to the motherboard's PWM pin to control the brightness of the light.
