Today the new project from Boldport Club arrived. It is called “The Cuttle” and it is a minimal configuration of the ATMega328-PU microcontroller with minimal elements to get it running.
As usual the PCB is artfully designed in shape of a cuttlefish. Soldering was easy this time.
Here some photos of the project how it arrived and at the end the final version with all components soldered into place.
I also made a short video where you see the ATMega in action:
The source code for the LED effect shown in the video is very simple:
void setup() { DDRD = 0xff; PORTD = 0x0f; } void loop() { const uint8_t first = ((PORTD & 0x80) != 0) ? 1 : 0; PORTD = ((PORTD << 1) | first); delay(50); }
