Touch sensitive arduino plant

in this tutorial, I am showing how to build a touch sensing plant using Arduino that is when you touch the plant  the colour changes

watch this tutorial video

first, watch this video

things needed

• Arduino (I am using Arduino UNO)https://amzn.to/2K16VGu
• 1 megaohm resistor
• 3*LEDs( chosen your colours)

circuit diagram

I made a circuit diagram using fritzing software

connections

first, connect 1 megaohm resistor between  pin 2 and 4 of Arduino

then attach the touchline  to pin 4 also connect the other end to your plant

now connect 3 LEDs(different colours) to pin5, 6, 7

if you are using RGB LED  then connect the common ground to ground  and connect other pins to Arduino digital pin 5, 6, 7

this project works base on the change in capacitance so we are using capacitivesensor.h library

download library from here

download Arduino code from here

connect Arduino and plant  with some good conducting wire like copper and also use  good plants  I mean water-rich plants like magic bamboo, water Lilly
