YES! Thanks B! My current design uses a TLC555 one shot and SN4027B JK flipflop in Toggle mode. The flipflop would control the Reset input of the 555 High and allow only one output pulse, i.e., the FF would be toggled by the 555 output pulse, setting the 555 Reset LOW, i.e, disabled. BUT, the...
Thanks KS and D. Have considered Arduino; too expensive and complex for my app. For D, my understanding of retriggerabls vs. non is that nonretriggerable cannot be retriggered DURING the output pulse, i.e. extend the pulse, but EITHER circuit CAN be triggered again after the output pulse has...
Need a circuit that, when triggered by a high-low transition, will issue one and ONLY one 1-second pulse. Would be reset by a pushbutton switch or by cycling power (preferred). Powered by batteries and 2950-type 5V regulator (slow power-on rise time.) Triggered by a proximity detector, Azoteq...
