| =====TASK===== | =====TASK===== | ||
| - | Taking our knowledge | + | This is part one of a sequence: decide on some project you’d like to pursue, this project lays the groundwork of understanding of individual components. |
| - | * wire up the multicolored LED (3 separate wiringPi GPIO pins) | + | * Part 1: Select some component(s) to explore (circuit and program |
| - | * we are going to use software PWM to control this, which will give us 100 levels of adjustment | + | * Part 2: integrate together on some new circuit with other components (circuit and program |
| - | * wire up 3 buttons | + | * Part 3: Finished product (circuit, program) |
| - | * wire up the rocker switch to its own wiringPi GPIO | + | |
| - | * one direction will indicate positive | + | |
| - | * the other direction will indicate negative | + | |
| - | * implement logic so that, with the rocker switch in a given position, when pressing one of the color buttons, it adjusts that component of the multicolor LED in the appropriate direction (by a step of 10). | + | |
| - | * if a color value exceeds or dips below the allowed range, cycle it to the opposite end | + | |
| + | Peruse the [[https:// | ||
| + | |||
| + | And document your selection, progress, and final results on the project documentation page! | ||
| =====GRABIT===== | =====GRABIT===== | ||
| - | To assist with consistency across all implementations, | + | No grabit |
| - | < | + | It would be highly recommended to create a **eap0/** directory in your repository, alongside your other projects, and perhaps to call your program **eap0.c** |
| - | lab46:~/src/ | + | |
| - | </ | + | The **Makefile** from other projects can be adapted to work with your current endeavour (would only need to change perhaps one line near the top of the **Makefile** in a text editor). |

| - | The general flow of the process (one way of going about it, anyway) can be described as follows: | + | |
| - | + | ||
| - | < | + | |
| - | SET REDVAL, GRNVAL, BLUVAL TO ZERO | + | |
| - | REPEAT INFINITELY: | + | |
| - | SHOULD THE INCREMENT POSITION ON THE SWITCH BE SET: | + | |
| - | SET DIRECTION TO POSITIVE ONE | + | |
| - | OTHERWISE: | + | |
| - | SET DIRECTION TO NEGATIVE ONE | + | |
| - | + | ||
| - | SHOULD THE RED BUTTON BE PRESSED: | + | |
| - | ADJUST REDVAL BY (TEN TIMES DIRECTION) | + | |
