Simon Says game implementation with Raspberry Pi and Nerves.
- 4 buttons
- Raspberry Pi (I used a zero W but any other else would work)
- Experimental bread board
- Cables
- Piezoelectric buzzer (or a different color led)
- 4 different leds, blue, red, yellow and green
- 4 220 ohm resistors (the less, the brighter)
The gpio pin configuration is set within the GPIOConfig file, it can be modified as desire but apparently the input interrupts necessary for the buttons are not supported on some pins, the following configuration worked with a Raspberry Pi Zero:
@colors_gpios [red: 3, green: 5, blue: 9, yellow: 10]
@buttons_gpios [red: 4, green: 6, blue: 8, yellow: 7]
@buzzer_gpio 11
Each led requires an electric resistor in series, this is my config:
Nerves applications produce images for hardware targets based on the
MIX_TARGET environment variable. If MIX_TARGET is unset, mix builds an
image that runs on the host (e.g., your laptop). This is useful for executing
logic tests, running utilities, and debugging. Other targets are represented by
a short name like rpi3 that maps to a Nerves system image for that platform.
All of this logic is in the generated mix.exs and may be customized. For more
information about targets see:
https://hexdocs.pm/nerves/targets.html#content
To start your Nerves app:
export MIX_TARGET=my_targetor prefix every command withMIX_TARGET=my_target. For example,MIX_TARGET=rpi3- Install dependencies with
mix deps.get - Create firmware with
mix firmware - Burn to an SD card with
mix firmware.burn
