I am very new to electronics. New to this board as well.. So please excuse me if my board etiquette is lacking.
I have been given a delay timer circuit that I want to understand, and tinker with. I am very new to electronics and finding that deciphering a phrase or word is key to learning.
Discovering this forum has given me hope that there is a member or members that are sufficiently patient to walk me through this circuit.
The delay timer circuit is a small portion of a PWM motor control circuit. The purpose of the delay timer circuit is to provide a reset signal to a 555 timer so that regardless of the PWM circuit speed control setting, a 100% “Start Up” period occurs when the PWM circuit is turned on.
For the delay circuit:
First I want to understand the interplay of the 5 components and the resulting output of the circuit.
From that I want to experiment with altering the delay time by changing out components.
I look forward to any and all replies, and the learning from those replies.
