In recent times all makers make little hardware for Chrome Downasaur game, All are using SG90 servo motor, LDR, and Arduino microcontroller. Here I am think something different from the traditional flow. I also see posts of Chrome Downasaur game using python, they are using Arduino serial communication and use Python code for "space" bar input for chrome game. I like this method. But here I implemented something different. I am using digistump ATtiny85 board for control chrome game.
