DIY a Top-Drawer SD Card Read/Write with Arduino For Yourself!

Do you wish to have a small and portable SD Card Read/Write with Arduino, but it’s somewhat costly to buy it from the RadioShack? Well, then just Do It Yourself and you definitely can cut off the budget cost for sure. For today project, you must refer to the below schematic diagram. As you’ve noticed that the above schematic uses some resistors in a voltage divider, and its main point is to bring down the Arduino 5V logic to the SD Cards 3v3 logic. By this way, all the outgoing signals from the Arduino will constantly dropped to 3v3. When the 3v3 is above logic 1 for the Arduino, then the incoming signals to the Arduino are fined. In other hand, the 3v3 voltage supply from the decimelia was normally … Continue reading
