This question already has an answer here:
I am trying to connect the MMA5452Q accelerometer to arduino on 5V (later it will be substituted with attiny85, hence the 5V voltage). It works just fine when i supply arduino's 3.3V. When i try the 5V supply and split it with resistors (R1, R2, R3) the accelerometer does not work any more. I measured the voltage of the circuit. It is 1.1V but MMA5452Q requires 1.6-3.3V. I was trying different combinations but i am afraid that doing it blindly at some point I will just burn the chip. What is going on here? Could anyone tell me how to connect it so the voltage maches? (And how to calculate this - so I dont need to ask every time :) )
P.S. R5 and R4 are pull ups required by accelerometer's documentation. Works when the circuit is powered with 3.3V
P.S.S. I am not an electrical engineer. I am hoping that this question is not terribly stupid.
