ZAPNI / VYPNI jedným tlačítkom

24. 2. 2014

Po prehladávaní internetu som narazil na schému ovládania jedným tlačítkom. Pôvodne  to bolo určené na spínanie LEDky, ale po menšej úprave to dokáže aj väčšie zaťaženie.

Schéma bola zrealizovaná na nepájivom kontaktnom poli (Breadboard), alebo univerzálnej doske. Pôvodné zapojenie čo tam je nieje overené, staval som to podla schémy.

Môžem povedať, že to funguje vynikajúco, pokial viete ako tak sa dá spínať aj väčšie záťaže (motory, žiarovky poprípade malé lampičky).

Odber zariadenia pri LEDke je 0.01 A. Pri motorčeku (3V z CD mechaniky) asi 0.06 - 0.1 A





Obr 1. - Schéma zapojenia



Obr 2. - Zapojené ...




Obr 3. - ... a aj funkčné :)


Ak by ste chceli vedieť ako ten motor, tak miesto LEDky pripojíte tranzistor. Báza k rezistoru, Emitor ide do + (9V) a kolektor sa pripojí k + motoru.

Hey! I just wanted to ask if you ever have any trouble with hackers? My last blog (wordpress) was hacked and I ended up losing a few months of hard work due to no backup. Do you have any solutions to stop hackers? oreo bollar recept

I don't know if it's just me or if everyone else experiencing issues with your blog. It appears like some of the text in your posts are running off the screen. Can someone else please provide feedback and let me know if this is happening to them as well? This might be a problem with my internet browser because I've had this happen previously.
