Hi, I need to make a circuit which does the following thing:

When it sees a red object it will send output 0 until it sees a green 
object (like a well colored cubic toy), after it sees green it will send 
output 1 until it sees red again. ( If it is hard to implement I'm ok 
with just output 0 when it sees red and outputs 1 when it sees green, I 
mean it is ok if the outputs not continuous but it would be great if 
they are continuous)

I have basys3 and have to use VHDL. I think I should use TCS34725 sensor 
https://www.adafruit.com/product/1334 but I'm not sure I just assumed, I 
would be really glad if someone helps

Some extra questions: If it is possible I will implement it on a toy 
RCcar is it possible to connect it with Bluetooth module to get inputs 
or how should I do it ?- I can use another board JUST FOR CONNECTIONS my 
main Project should be on BASYS-3

Thanks
