Does anyone has idea on how to code Fastled character shifting from an android device input. badly needed anyone’s help. thanks!
The easiest way is with a bluetooth serial adaptor, like the HC-05.
You make the serial connection and use a serial terminal application from your android phone.
This article at Funkboxing gives all the details you will need to make it work -he has a full demo that has the complete Bluetooth control code in it: http://funkboxing.com/wordpress/?p=2154
we are actually using an annikken andee as a module for our bluetooth connection. we used it because it has bluetooth, android and sd card modules. do you have any other ideas on how to do it?
I don’t know what else to tell you - I already told you how to do it - use bluetooth (you are) and look at Funkboxing’s demo code, which has the whole bluetooth/FASTLed interface mapped out.
I guess I am confused as to where your problem lies - you have an app, you have bluetooth, you have arduino, you have code. You just need to hook them all together.
Have you gotten your bluetooth module working controlling your arduino yet?
(and FWIW, that US$79 module you bought could be done for less than $10 with one each of bluetooth and SD card modules)
