Maker Garden aims at promoting the spirit of recycling and protecting the environment, therefore, it is consist of discarded plastic bottles.There are some leds inside the bottles that are connected to arduino to make it sensor lights. Moreover, to highlight the maker spirit, it has been empowered with different elements, such as classical comic characters, logo of some open source hardware.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Step 1: Shape the Plastic Bottles
We cut the plastic bottles into 2 half and connect them with fine line.
Step 2: Step 2: Design the Logo and Prepare Your Flowers
To highlight the maker spirit,we add different elements in it,such as classical comic characters, logo of some open source hardware.
The logo card can be stick on the bottle while flowers can be place in the bottle.
Step 3: Step 3: Install the LEDs Into the Bottle
LEDs are placed in the bottle cap.And the long electrical wire go through the cap to power the LEDs.
We parallel the LEDs and connect them to the arduino's analog ouput interfaces(D9 D10 D11).As a result, we can achieve the effect of breathing on the LEDS.
Step 4: Step 4: Set PIR Motion Sensor
This sensor allows you to sense motion, usually human movement in its range.when anyone moves in its detecting range, the sensor outputs HIGH on its SIG pin.In our maker garden,the PIR Motion Sensor is powered by the arduino and we connect its SIG pin to the arduino’s D2 pin and set D2 pin as input.You can place it anywhere you want, the premise is that your data line should be long enough.

Step 5: Step 5: Hang Up on the Wall
Let 's start to decorate the wall now by hanging up our bottles and arduino!
Step 6: Making It Better
For more cool effect, we add a LED strip in maker garden,remaking it by a grove-relay module so that we can use the arduino to control it.
The Grove-Relay module is a digital normally-open switch. Through it, you can control circuit of high voltage with low voltage by the arduino.When set to HIGH, the LED on the module will light up and the relay will close allowing current to flow.So we could use the digital output on the arduino to light up the LED strip.
You can also integrate the circuit by using Fusion PCB service from Seeed.
