I am trying to prep my wiring for a 8x8 Led Matrix w/ Bluetooth according to the following instructable:
Instead of soldering everything together I'd much rather use a breadboard. I'm new to wiring, breadboards, and Arduino's in general. I was wondering if anyone could look over my sketch and see that the connections I've made are valid.
I'm basing my wiring off this image (See original instructable for higher resolution):
I realize the bluetooth module isn't the same. I'm just using this as a reference. The wires leading off the top of the board will be going to the LED Driver module.
EDIT: Thanks for the feedback guys. I have decided to go with the Innogear HC-05 module. I've adjusted the wiring according to that model. As per the suggestions, I've switched my power and ground rail and eliminated the resistors and ground for TX communication. (I've still kept a ground for the BT). Here's my new attempt:
