I am working with a Stalker (V1.0 with the 168 MCU) and it appears that the working voltage is 3.3V for this. I understand that this is necessary for the xBee and storage card, however all the shields that have any analog voltage requirements to them seem to have a problem with this. In particular I am working with the LCD keypad shield from DFRobot and it uses a single analog input pin to read 5 different buttons by having each button connect via different resistors which then gives 5 different voltages. This works fine for 5V arduino’s but when the reference voltage is 3.3V then half the buttons don’t work… I’m wondering if this is something that has been addressed in the V2 stalker with the 328. I tried to look this up on the website, but the 328 version datasheet and manual links just have the 168 information on them. If this hasn’t been addressed in the 328 version, is there a reasonable workaround for this??? Any information is greatly appreciated.
