Arduino LED Blinker
Make a circuit that blinks a red LED once per second.
Power it with a 9V block battery through an on/off switch.
Use components that are easy to hand-solder.

Make a circuit that blinks 3 LEDs once per second and a place where i can mount an arduino nano.
Power it with a 5V DC Power jack.
Use components that are very easy to hand-solder and trace bigger circles to drill later

No design changes were made; the project remains empty. Execution is unavailable because the account has no ACUs.
Remaining work: create the 5 V DC-jack input and protection, Arduino Nano mounting headers, three LED/resistor channels blinking at 1 Hz, hand-solderable through-hole footprints, and large plated mounting/drill holes, then verify the schematic and PCB layout.
