Consider the Type of Arduino LED Pixel Lights
There are different pixel lights, including digital and analog lights. The digital lights have an LED chip in each LED, while the analog lights have an LED chip per strand. The choice depends on the design since digital lights offer more control than analog lights.
Control and Addressing
These lights require control by microcontrollers like Arduino boards. The lights are controlled through data sent from the microcontroller. Each light is assigned an address to control it individually. The choice of board depends on the pixel lights. For example, the ESP8266 is suitable for light strips, while the Arduino Uno is ideal for smaller projects.
Power Supply
Pixel lights consume a lot of power, especially when all LEDs are on. Therefore, a power supply is needed to ensure the lights function properly. When choosing a power supply, consider the number of LEDs and the voltage they operate on. Also, choose a power supply with a higher ampere than what the pixels consume. For instance, a strip with 30 LEDs that uses 0.24A per LED should be powered by a 7.2A supply.
Data Transmission
Signal degradation can occur when the distance between the pixel lights and the microcontroller is long. This can lead to incorrect pixel lighting. Therefore, use repeaters to maintain data integrity over long distances. Additionally, use shielded cables for wires longer than 10 meters.
Voltage Drop
When the voltage supplied to the pixels is inconsistent, it can cause brightness variation from one end of the strip to the other. This is known as a voltage drop. To maintain uniformity, cut the light strip and connect it to a separate power supply that will deliver consistent voltage.
Water Resistance
If the pixel lights are to be used in areas that are exposed to water, choose lights that are water-resistant. These strips are covered with a silicone sheath that protects them from water damage.
