In this project, we\u2019ll demonstrate how to make a colorful, king-sized coconut tree (5 feet) decorative showpiece using a digital RGB LED strip.\u00a0<\/span><\/p>\n

The RGB LED strip is cut and arranged to form the shape of a coconut tree. The ATMega328 microcontroller is used to control the LED strip, generating several flashing, fading, and blinking LED effects. Much like a light show, more than 15 different multicolour effects will run continuously.\u00a0<\/span><\/p>\n

The structure
\n<\/span><\/strong>To build the tree structure, we\u2019ll use 1-inch diameter PVC pipes, as well as L- and T-joints. These joints are used for the tree\u2019s base stand. The leaves are made of medium-thick 1mm2<\/sup> copper wire.<\/span><\/p>\n

We’ll also use a circuit box and a 12V@2A adapter. Additionally, to assemble everything, a hot glue gun and transparent tape is required.<\/p>\n

The steps<\/strong><\/p>\n

1. <\/strong>To prepare the tree\u2019s base stand, which has four legs, use four L-joints and three T-joints. Two L-joints and one T-joint make one side of the stand (then repeat). There are two sides (about 30-35cm tall) as shown in the above images.
\n2.<\/strong> The rubber stands must be fixed to all four legs to ensure a stable grip.
\n3.<\/strong> Join both sides of the stand using one of the T-joints at the center.
\n4.<\/strong> Add the main pipe (150 cm) to the center T-joint.
\n5.<\/strong> Using a hot glue gun, carefully affix four of the 1mm2<\/sup> copper wire pieces (about 30-35cm long) to the top of the main pipe. Once secure, bend the wire to create a coconut leaf-like shape for the tree.
\n6<\/strong>. Using transparent tape, stick the RGB LED strip to the main pipe and the copper wire pieces.
\n7.<\/strong> Attach a small circuit housing box to the tree\u2019s base stand, and connect the LED to the circuit using the 3-pin connector (provided on the box).
\n8.<\/strong> Carefully connect a 12V@2A adapter to the circuit box. It powers both the circuit and LED strip.<\/p>\n

After creating the tree-like structure, we\u2019ll need to build the circuit.<\/p>\n

Circuit diagram<\/strong><\/p>\n

\"\"<\/a><\/strong>The circuit only requires a few components. It uses the ATMega328 microcontroller, LM7805 voltage regulator chip, a 16 MHz crystal, a 10K resistor, two 22pf capacitors, and a micro push button.<\/p>\n
