We'll also need an external 3.3v power source to power the chip. We'll simply add an 100ohm resistor here to prevent the the module from being overloaded.

The MISO pin will transmit to the parallel port at 3.3v, which the PC will still recognize. We'll need use a few resistors to create voltage dividers that will step down the parallel port's 5v transmission levels to the chip's 3.3v levels. For the chip to communicate with our PC, we'll need to connect the SPI pins into these pins of the parallel port.
But luckily, this module actually uses the same chip (the BC417) as the RN-42 bluetooth module, which also powers the $40 BlueSMiRF HID modules. By itself, this module isn't HID capable. This cheaper module is the HC-05 and sells for around $3 on ebay. The flashing process of the HC-05 itself takes no longer than a minute after we have extracted the firmware from the RN-42 once. It may look like there's a lot of steps below, but it's actually just a very thorough guide. With a bit of a firmware hack though, we can turn this cheaper module into a bluetooth HID module.

An inexpensive bluetooth serial module commonly used by hobbyists, the HC-05, sells for $3 USD, but is not HID capable by default. If we're looking to build our own bluetooth HID device, the hefty price of a single HID module can spike the budget of a project (like the BlueSMiRF HID for $40 USD, or the BlueFruit EZ-KEY HID for $20 USD).
Bluetooth HID (human interface device) modules will let you create bluetooth peripherals that can pair with mobile devices out-of-the-box (like bluetooth keyboards, gamepads, mice, etc.).
