Today was another big day for the guitar hero bot. Firstly, we finished up wiring all of the internals for the guitar, including wrapping the wires in heatshrink tubing to keep them tidy. Additionally, we cut an opening at the top of the guitar to act as a receptacle for the 9V battery that powers [...]

We got a whole lot done today. On the programming side of things, we’ve been working on getting the signals to go in through the microprocessor. There are a few things that the processor has to take care of…It needs to take in all signals simultaneously, and record their values (0 or 1) into a [...]

No, not really, it’s just got all five sensors and is quite accurate when analyzing “Through the fire and flames” on expert mode. Keep in mind, the signals that are currently lighting the LEDs, will be used to “press” the buttons in real time.

It’s honestly not that different from the first stage, but hey, it’s something. Here’s a peak at the second stage, 3 sensors and the accompanying LEDS for the green, red, and yellow notes.

We’ve successfully gotten the first stage of our guitar hero bot working. In the video below, you can see a prototype of our photodiode circuit correctly viewing the notes on the screen, and blinking the LED appropriately. For now, We are only detecting the green notes, but more are soon to come. If you look [...]
