I would have to look at the options, but apparently some of the Tinys have plenty of GPIO and even a UART.  Might have to do without ADC, but in that case could use I2c light sensor or similar for example.  Also would still want one that operates at ~2V.<br>

<br>
If you see any that fit the bill please do point them out to me.<br>
