Hi, guys. Now I'm working with Arduino mini 04(5V), MMA7361 breakout of sparkfun(3.3V), 3V battery and step-up breakouts(5V, 3.3V).
My question is, When I directly connect digital pin of arduino and Sleep or Selftest pin of MMA7361, is there any problem? Or should I use any resistors between those pins to pull down Voltage?
I already connect 3.3V step up breakout to Vcc of MMA7361 and 5V step up breakout to +5V of arduino.
