The Circuit
This circuit can be made with parts in the SparkFun mbed Starter Kit. Also, keep in mind that the LPC1768 box contains a USB mini-B cable for programming
and power.
Parts List
To follow this experiment, you would will need the following materials if you did not order the SparkFun mbed starter kit. You may not need everything though
depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.
Heads up! For anyone ordering the parts separately from the SparkFun mbed starter kit, you will need to solder the header to the microSD socket's
breakout board.
