A o ni lo 555 timer IC ni ipo monostable lati ṣẹda akoko idaduro. Nigbati a ba fa, akoko naa yoo mu relayi ṣiṣẹ fun akoko kan ti a ti sọ tẹlẹ ṣaaju ki o to pa a. Ise agbese yii rọrun ṣugbọn o munadoko, ti o jẹ ki o jẹ afikun nla si irinṣẹ itanna rẹ. Fun alaye ti o han diẹ sii, rii daju lati ṣayẹwo fidio naa (ni fidio ni 02:15).

Itumọ Ẹrọ

Awọn eroja pataki ti iṣẹ akanṣe yii ni RJT520 relay, 555 timer IC, ati ipese agbara. RJT520 relay jẹ relay agbara-giga ti o le yipada awọn ẹru to 20A, ti o jẹ ki o yẹ fun iṣakoso awọn ẹrọ nla. 555 timer IC jẹ eroja ti o ni ọpọlọpọ awọn iṣẹ ti a le ṣeto ni awọn ipo oriṣiriṣi, pẹlu ipo monostable, eyiti a yoo lo fun akoko wa.

Relay naa ṣiṣẹ nipa lilo electromagnet lati yipada awọn olubasọrọ ni ọna ẹrọ. Nigbati iṣakoso 555 ba ga, o n ṣiṣẹ coil relay, ti o pa awọn olubasọrọ mọ ki o si jẹ ki lọwọlọwọ kọja si ẹru ti a so. Eto yii jẹ anfani fun awọn ohun elo ti o nilo iṣiṣẹ latọna jijin tabi adaṣe.

Ilana Asopọ

Lati so awọn asopọ ti iyipo akoko RJT520, bẹrẹ nipa sisopọ IC akoko 555. So pin 1 (GND) ti akoko 555 si ilẹ ti ipese agbara rẹ. Lẹhinna, so pin 8 (VCC) si itanna to dara ti ipese agbara rẹ (6V si 18V).

Ni atẹle, so pin 2 (TRIG) pọ si iyipo ìmúṣẹ rẹ tabi ifihan ifihan. Pin yii yoo mu akoko ṣiṣẹ nigbati o ba gba pulsi kekere. So pin 3 (OUT) ti akoko 555 pọ si ọkan ninu awọn itọnisọna ti coil relay, ki o si so itọnisọna keji ti coil pọ si ilẹ. Maṣe gbagbe lati fi diode kan si kọja coil relay lati daabobo circuit naa lati EMF pada.

Fun awọn abajade relé, so ọkan ninu awọn ibudo gbogbogbo pọ si ẹru ti o fẹ lati ṣakoso, ati ibudo keji si orisun agbara. Rii daju lati so ibudo keji ti ẹru pada si ilẹ gbogbogbo. Nikẹhin, tunto awọn eroja akoko (resitọ ati capacitor) ti a so pọ si awọn pin 6 ati 2 fun idaduro ti o fẹ.
