Picture of Avatar PlaNT (Touch Sensitive)
It is an avatar plant with LEDs all around. Once the plant is touched, LED turns on. You only need to use several LEDs and resistors with arduino. Of course, if you want to light up an avatar  forest, you can also connect all plants together.

Step 1: Preparation

Picture of Preparation
+ basic soldering
+ zero programming skills

Time:30 minutes

+ a plant
+ an Arduino
+ 4-10 LEDs
+ resistors ( one 10k Ω  and  4-10 220Ω  if it is a red LED)
+ dozens of  jumper wires
* We highly recommend you to use smaller LEDs such as 3 mm LED and thinner  jumper wire so they can be nicely hiden in the plant.

+ Soldering iron and solder

Step 2: Soldering

Picture of Soldering
Here we used 4 LEDs for a small plant.
+ blend both legs of all LEDs horizentally
+ solder both legs with jumper wires and a 220 Ω resistor on either side.
   ( Don‘t forget to take a look at the long (+)  and short (-)  legs of LEDs. Legs with the same polarity should be placed in the same side)  

Step 3: Build the circuit on Arduino

Picture of Build the circuit on Arduino
Above is the circuit you will be creating.
+ connect LEDs to PWM pin like D3 and to the ground
+ connect a 10k resistor to D8 and D7
+ connect a wire to D8 and to the plant in its stem

Step 4: Complete programming on Mind+

Picture of Complete programming on Mind+
Mind+ is a free graphical programming software for Arduino, specially for artists and DIY enthusiasts without programming background.
Instead of writing codes on IDE, you can easily make a program with only 3 software modules for this project, Capacity Sensor, IF and LED.
Capacity Sensor--  to detect if a hand touch the plant
IF -- to evaluate the condition
LED -- If a hand touch the plant, then LED lights up.

You can download our free software Mind+ (available on windows, Mac and Linux) and follow the instruction in the picture above.

Neat project. Fav

Mimosa pudica, It's a real plant that is touch sensitive! If you lazy and or don't have the parts to make this lol

You can find any plant to make this project, preferably plant with more water on the stem so it is more conductive.

real funny project!!! like a avatar mushroom at movie
the software is new one?never meet before but looks nice
