In this article we will complete the our second project Topic : Python code for IoT Ambient Light Zerynth Lamp . in this project we use Zerytnh App to control a NeoPixel LED strip via mobile using the Zerytnh App, that shows a color picker and a menu for the selection of various pre-configured animations.

Follow the following step one by one :

step 1 : project pre-requirement 

Zerynth Elements:

1. Zerynth Studio
2. Zerynth App
3. Zerynth Shield

Other products :

Arduino DUE / ST Nucleo F401RE / ParticlePhoton./ UDOO or Flip&Clip by Mikroelektronika.

step 2 : connectivity for Python code for IoT Ambient Light Zerynth Lamp project

•  Just connect the Zerynth Shield and wifi Shield onto your Arduino IDE. If you use Particle Photon just connect it onto the dedicated connectors on the Zerynth Shield.
• And then Connect the NeoPixel LEDs to the related port on the Zerynth Shield.
• finally Put all the boards and the LEDs into the Lamp.

step 3 : Python programming code for Python code for IoT Ambient Light Zerynth Lamp :

# First you need to import needed modules 

import streams

from bcm43362 import bcm43362 as wifi_driver

from wireless import wifi

import animation

from toishield  import toishield



# After import the above library or module import you need to import the zerynthapp module

from zerynthapp import zerynthapp



streams.serial()



# Below code use for connecting the wifi network

try:

    wifi_driver.auto_init()



    print("Establishing Link...")

    wifi.link("SSID",wifi.WIFI_WPA2,"password")



    print("Ok!")

        

except Exception as e:

    print(e)





# save the template.html in the board flash with new_resource

new_resource("template.html")



#### ZerynthApp Setup



# :: Javascript to Python ::

# the following functions will be called when buttons are pressed

def change_color(r, g, b):

    animation.setup_color(r, g, b)



def change_animation(n):

    animation.setup_anim(n)



def change_speed(n):

    animation.setup_anim_speed(n)



# configure the Zerynth app with a name, a descripton and the template url

vp = zerynthapp.ZerynthApp("Zerynth Lamp", "Try me!", "resource://template.html")



# everytime Javascript generates events the corresponding functions are called

vp.on("change_color", change_color)

vp.on("change_animation", change_animation)

vp.on("change_speed", change_speed)



# run the ZerynthApp!

vp.run()



# since vp.run starts a new thread, you can do whatever else you want down here!

# let's control leds



animation.start(D6, 24)

Finally we are finished the coding works, If you have any query regarding this project then visit to arduino official site.

Summary :In this article we saw Python code for IoT Ambient Light Zerynth Lamp. if any problem about this project then please ask me.

BEST OF LUCK!!!
