Adding LEDs to Schematic
Worked for 3 mins 44 sec
Done — I rewired the design for one 12 V barrel jack cable:
J_PWRnow creates 12V_IN- KR1201A V+ / V- are powered directly from 12V_IN / GND
- Added
PS_5V_BUCKto convert 12 V → 5 V - Arduino Micro, servo, LEDs, and display now use the buck-derived 5V
- KR1201A relay output is wired safely into Arduino
0/RXas a dry-contact input withR_KR_PULLUP; no 12 V goes into the Arduino input
I updated Alarm Clock Design Notes and the firmware starter. The only remaining ERC item is the intentionally unused Arduino
VIN; that’s correct because the Arduino is powered from regulated +5V, not its onboard VIN regulator.can you add a seperate 5.1kohm resister for each led?
Worked for 12 sec
I’ll replace the shared LED ground resistor approach with five individual 5.1 kΩ resistors, one in series with each LED cathode to ground, then verify the updated LED nets.
Worked for 1 min 31 sec
Done so far:
- Added four new 5.1 kΩ resistors:
R_LED2,R_LED3,R_LED4,R_LED5 - Reused the existing
R_LED_GNDas the individual resistor forLED1 - Broke the old shared LED cathode net
- Rewired each LED cathode through its own resistor to ground:
LED1:K → R_LED_GND → GNDLED2:K → R_LED2 → GNDLED3:K → R_LED3 → GNDLED4:K → R_LED4 → GNDLED5:K → R_LED5 → GND
I was blocked before I could run the final verification/review pass. The remaining step is to verify the LED nets and run ERC checks to confirm there are no new schematic issues.
