arduino nano, xbee, rotary encoder
An arduino nano (left, with bright blue light) being the controller in this setup. adafruit 7-seg LED backpack module (i2c, 5v) is the display. there are 2 xbees: one on usb, inside the plastic box (top) and one on the proto board with the bright red led. on the bottom of the board is an ftdi-like (lol) usb/serial ttl 5v/3.3v board. upper top is a cheap ebay rotary encoder with plastic knob.
I'm testing out some code to read the encoder, write to the numeric display and update values over xbee radios. the bottom serial board can be used to sniff the traffic or you can use the xbee to send data to its peer. the output is ascii and you can watch it via 'putty' on windows or any term program you want.
both the ftdi board and the xbee are on software-serial arduino pins and I limited the speed to 19200 for that reason.
for short distances, so far its pretty responsive. the encoder works well, the arduino scans it fast enough to not miss any turn events and the led display is sharp, bright and also very fast to update/write to.
