How can I reduce current drawn by micro SD card module? I am using a servo along with a sensor and micro SD card module and speaker in arduino uno in order to play a wav file at certain conditions . But when i run the whole system the sd card module is consuming high current and the servo stops working as the current in that is in order of some micro amps. So please help me to solve the problem.
another good practice might be to add a Transistor to your Systems so that you can physically disconnect parts of your System from the power rail while not in use. this will obviously decrease power consumption...
