Electronic Lock SmartCard4 with AVR AT90S2313 lectronic lock SmartCard4 is Security arrangement activity based on AVR AT90S2313, agnate dent with ATtiny2313. Rudi Slejkovec uses Baskom AVR to abridge the code. The advantage from this activity is it has baby physic, accessible to accomplish and use. It provides added advantage to its assurance back the adapter [...]

This is a ultrasonic radar project with many practical applications in security and alarm systems for homes, shops and cars. It consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area covered by the circuit the circuit’s fine balance is disturbed and the alarm [...]
