#157313 - timer |
Hai,
This may be off topic. I want a variable timer 15s-25s. Depending on the user selection, the output should vary. Once the button pressed, the output should give that much delay. Can anybody give simple solution either with uC or without uC? It should include delay selection also. Thanks JPRao |
