I'll review the provided schematic and connections to check if there are any issues or potential improvements.
General Observations
- Power Supply and Grounding:
- Ensure that all components needing a specific voltage (e.g., 5VDC) are getting the correct voltage.
- Check all ground connections for consistency.
- Potential Signal Paths and Interfaces:
- Verify that control signals are connected logically and match the intended function.
-
Connections to Relays, Transistors, and TRIAC:
- Check the connections related to the control circuitry and the load-switching components (TRIAC, transistors, and relay).
-
Microcontroller (U2 - ATTINY13V-10SSU):
- Ensure proper power supply to VCC and connection to GND.
- Ensure the RESET pin (
RESET/PB5) is properly handled. - Validate that I/O pins (e.g., PB0, PB1, PB2, PB3, PB4) are connected correctly.
-
Power Supply (PS1 - IRM-10-5):
- Verify correct AC connections:
- Connect J1:PIN1 to PS1:AC/L.
- Connect J1:PIN3 to PS1:AC/N.
- Validate DC output connections:
- Connect PS1:+Vo to Net 16.
- Connect PS1:-Vo to Net 13.
- Verify correct AC connections:
-
Switch (SW1 - MRX108-A):
- Make sure all intended switch connections (e.g., SW1:A to R6:1) are logically consistent to the intended control input and output paths.
-
R2 (4.7k resistor):
- Verify connection:
- Connect R2:P1 to RV1:P3.
- Connect R2:P2 to Q1:A2 and J2:P2.
- Verify connection:
-
TRIAC (Q1 - BTA16-600BW):
- Validate connections:
- Connect Q1:G to D1:A ($Net 1$).
- Connect Q1:A1 to $Net 8$.
- Connect Q1:A2 to $Net 4$.
- Validate connections:
-
Diodes:
- Ensure D1, D2 are correctly biased and connected:
- Connect D1:K to $Net 7$.
- Connect D1:A to Q1:G.
- Connect D2:A to Q2:C and U1:~ ($Net 10$).
- Connect D2:K to $Net 16$.
- Ensure D1, D2 are correctly biased and connected:
- C1 and C2:
- Ensure capacitors are correctly oriented and connected to the proper nodes.
- Typically, one pin to ground and another to the desired line to decouple noise.
- Net Components Exclusivity:
- Check if any net components excluded from BOM or PCB might affect the design's functionality.
- Overlapping Connections:
- Ensure no unintended connections between components and nets, which could result in shorts or circuit misbehavior.
I'm assuming no specific issues regarding component placement or routing constraints beyond this check.
Next Steps:
To identify more detailed issues, we'd typically simulate the design or perform a thorough peer review considering real-world constraints and specific requirements of the dimmer circuit. Would you like a specific part of the circuit to be checked in more detail?
