Using RGB LED strip lights and a controller, you can change the colour, brightness, temperature and other attributes of your lights to set the perfect mood. The solution: I found this strip case that diffuses the light well and you can screw it to a shelf, for example, if you want a permanent solution. In this example, the WS2812B LED strip will be powered using the 5V Arduino pin. In my case, I’m controlling 14 LEDs. If you want to control manyLEDs, you’ll need to use an externalpower source.

Thank you for your attention. And for your indulgence for the automatic translation, my language being French… Reply leds[pinNo] = CRGB( 0, 255, 0); // Set all 45 LEDs to green color // If an object is detected on top of the particular sensor, turn on the particular led if ( digitalRead(pinNo + 3) == LOW ) {

Schematics

In my opinion, this is the coolest type of LED strips. You can control the brightness and the color of each LED individually, whichallows you to produce amazing and complex effects in a simple way.

LED strip lights come in every imaginable colour from red, blue, and green to warm whites and pure white. The LED strip shouldbe powered using a 5V power source. At 5V, each LED draws about 50mA, when set to its full brightness. Thismeans that for every 30 LEDs, the strip may draw as much as 1.5 A. Make sure you select a power source that matchesthe strip’s needs. An AC to DC power adapter that provides 5V and 2A should do the job: In the following figure you can see my WS2812B LED strip. It is 5 meters long and the LEDs are enclosed in a weatherproof silicone. So, they can be left outside at the rain and dust without any problem. Desctiopion: First we need to define the basic parameters as explained earlier and set the 45 proximity sensors pins as inputs.In your setup function we will set our Arduino pins to output. We will also call a couple of functions with a 5 second delay in between. These functions don't exist yet, but don't worry, we'll get to them. void setup (){ They come in 4 meter reels with a 2 or 3-pin JST SM connector on each end and separated power/ground wires. These strips are sold by the meter! If you buy 4 meters at a time, you'll get full reels with two connectors. If you buy less than 4m, you'll get a single strip, but it will be a cut piece from a reel which may or may not have a connector on it.If the piece comes from the end of the reel, the connector may be on the output end of the strip! Step 3: In the void loop(), I have used 6 different cases for LEDs to create some magic. In CRGB(0, 0, 0 ) function, 1st argument is red, the second is green, and the third is blue.

If you want to use another pin of the Arduino to control the LED strip, you need to change the LED_PIN variable: #define LED_PIN 5 Demonstration

Using an LED Strip Case

Third, just because you have all those pixels doesn't mean you have the RAM for it - the entire strip must be buffered in memory, and we've found many Arduino UNO projects only have about 1500 bytes of RAM available after all the extras are included - enough for about 500 LED pixels. If you want to drive the entire strip and have some other libraries included, use a Mega. First, Initialize the serial monitor and set the baud rate at 9600 speed. FastLED.addLeds(LEDs, RGB_LED_NUM); Connect a capacitor with a capacitance between 100uF and 1000uF from power to ground to smooth out the power supply.
