Things seem a little quiet here lately so I thought I'd give a rough summary of my latest I can do that with my Modulos.
A "friend" pointed me at the cookie clicker website. You can google it. but it's a silly game where you have to click a big cookie on the screen. Apparently he got a little hooked on it but needed to make his number of cookies go up faster. Well the Modulo with the controller uses Atmel SamD21 which should support the mouse and keyboard HID usb needed. I couldn't get a straight answer on the particle sadly.
So grabbed a base, a controller, a display, and a knob. some quick work on the mac and Arduino IDE and and I have a workable sketch, where you click the knob and the controller becomes a mouse and will click fast. add some status output including which button is clicking and the rate onto the display. Have the display buttons choose left, middle or right button. And there you go. happily clicking away near my friends USB mouse limit around 13/14 clicks per second.
