## Hello, 💡
Now that you've set up your own project from scratch, you could start playing around with it by turning on one of the DK's on-board LEDs using only the HAL. Some hints that might be helpful there:
- Before you dive into interrupt handling on your own, work through the advanced material of this course to learn about [RTIC][rtic]
- The [Embedded Rust Book][embedded rust] is a great reference, especially the Concurrency chapter.
- The [Nordic Infocenter][infocenter] tells you which LED is connected to which pin.

## (extra) adding addresses to packets
> have people use the `ieee802154` crate to add a MAC header to the radio packet. New dongle firmware would be required to respond differently to broadcast packets and addressed packets

- [nRF52840 Product Specification 1.1](https://infocenter.nordicsemi.com/pdf/nRF52840_PS_v1.1.pdf)
- The [Embedded Rust Book][embedded rust] is a great learning resource, especially the Concurrency chapter.
- If you are looking to write an interrupt handler, look at the [`#[interrupt]` attribute][interrupt]. All interrupts implemented by the nrf52840 hal are listed in [`nrf52840-pac/src/lib.rs`][pac].
It is also recommended that you work through the advanced material of this course to learn about [RTIC][rtic].
