  <title>[elecena] Adafruit Tower Light - Red Yellow Green Alert Light with Buzzer - 12VDC - zmiany ceny</title>
  <description>The Red-Yellow-Green Alert Light offers a versatile solution for monitoring various statuses from project progression to machine operation or restroom occupancy. This adaptable tower light is designed in a sleek Adafruit black finish.Features include easy installation with mounting holes and a 180-degree adjustable light mount. Control is straightforward: connect the brown wire to a +12V power source, and ground the red, yellow, or green wires to activate the corresponding LED lights.A separate orange wire manages a buzzer, providing an auditory alert when needed. Ensure maximum brightness by illuminating one light at a time. Buzzer functionality remains independent of light status.Ideal for use with a 12VDC power supply, it's also compatible with 3V or 5V microcontrollers through 4 x NPN transistors or N-channel MOSFETs to manage current. For lower voltage applications, customized LED wiring might be necessary. Note that shipping weight aligns with UPS's dimensional weight guidelines.</description>
