Piezo Driver Circuit with LED Warning Indicator

single IC piezo driver

Basically we are talking about a single IC that is “integrated circuit” for those of you who are not total tech nerds – that can act like a warning system, complete with both a super annoying beeping sound and a flashing light. You know, just in case you are hard of hearing or visually impaired…sort … Read more

Simple Shadow Sensor Alarm Circuit

shadowdetectorcircuit 1

Utilizing two LDRs, the mentioned shadow detector circuit efficiently detects variations in light intensity and sounds a loud warning siren. The method of detection might not be as precise in circuits that just employ one LDR (photoresist) as it is with the two LDRs covered here.The following is a study of the shadow detector circuit’s … Read more
