Hi I've been looking at some projects where a wii nunchuk is interfaced to an Arduino to control a set of servos
Looking at the pinout of a Wiimote it only seems to have 3.3v and all the circuits I have see wire the nunchuck stright into the 5v line of the Arduino.
Is this safe ? Do I not risk frying my nunchuck doing this
Also I don’t have a regular Nintendo Nunchuk I have a 3rd party wireless one. The bit that would be getting the 5V is the wirelesss tranciever that would normally be plugged into the base of the wiimote. so even if the numchuck is safe to run at 5v how can I be sure the tranciever is
If I play it safe and run everything off a 3.3v supply instead does this have any effect on the output values and will I need different code to translate it.
Regards
Glen
