# PC817 Series PhotoCoupler Tester
|
||
|
||
Simple test setup for the **PC817 optocoupler family**.
|
||
Goal: quick validation of parts and basic frequency response.
|
||
|
||
## Project Scope
|
||
- **Part check**: Verify if a single PC817 is functional (on/off behavior).
|
||
- **Frequency response**: Measure switching speed with an external signal source (Siglent arbitrary generator) and scope.
|
||
|
||
## Notes
|
||
- Two independent circuits:
|
||
1. **Basic LED–Transistor test** for functionality.
|
||
2. **Frequency response test** for rise/fall times and cutoff.
|
||
- This repo contains only the **blueprints and notes**.
|
||
No final PCB or kit planned.
|
||
|
||
## Status
|
||
Planned as a short **8h project** → quick results only.
|
||
A detailed write-up may follow on the Tōgō-Lab blog.
