Rust project for the Arduino Nano that implements binary counting with LEDs.
Arduino nano.
USB type A (or whatever type your sender accepts) to Micro USB or USB type C (depending on your Arduino Nano variant)
A breadboard (at least from a1-j30 which should be the smallest one).
4 jumper wires (male to male).
3 resistors (I'm using metal film blue ones).
3 LED diodes (the colors don't matter).
Arduino from d30 to j16.
Jumper cable at GND (in this case: d19 or j17) to negative column at the j column side.
3 Jumper cables:
- d30-a1 (pin.d12)
- d29-a5 (pin.d11)
- d28-a9 (pin.d10)
3 Resistors:
- b1-i9
- b5-i5
- b9-j9
Some vocabulary for the LEDs:
- Anode - the long end (positive charged): the part where oxidization happens.
- Cathode - the short part (negative charged): the part where reduction happens.
3 LEDs:
- Anode: j1 | Cathode: at the negative column
- Anode: j5 | Cathode: at the negative column
- Anode: j9 | Cathode: at the negative column
Note
The position of the cathodes on the negative column doesn't matter as long as they're on the column where the GND jump wire is connected.
For reference, it should look something similar to the following:
-
Install prerequisites as described in the
avr-halREADME (avr-gcc,avr-libc,avrdude,ravedude). -
Run
cargo buildto build the firmware. -
Run
cargo runto flash the firmware to a connected board. Ifravedudefails to detect your board, check its documentation at https://crates.io/crates/ravedude. -
ravedudewill open a console session after flashing where you can interact with the UART console of your board.
