Astable circuit movement? Answered
im using the circuit and the calculator in this link
it works fine , but the movement from (low) to (high) goes very fast and sudden , and so the movement from low to high .
what i want is gradual (ascending) increase from low to high , like 4 seconds or something , then sudden decrease to low , then gradual increase to high again , and so on
what changes should i do , or what circuit should i use ?
any links or information would be helpful
thank you :)
