NE555 Timer Schematic Design
I need the IR LED output modulated at 38 kHz, not just a steady 2-second pulse.

You want the NE555DR-based schematic updated so the IR LED is driven with a 38 kHz modulated output instead of a steady 2 s pulse.
- I updated the plan to:
- define PIR/TSOP1838 roles,
- add the 38 kHz modulation stage,
- connect the sensor and IR LED driver paths,
- verify the triggered behavior.

The plan is ready to run.
- Please click Start on the plan bar to begin execution.
- If you want, I can also update the plan first with any last-minute requirements like:
- supply voltage
- IR LED current target
- PIR output polarity
Set IR LED current
Define supply voltage
Set PIR polarity
