@thulin247, For at nogen kan prøve at hjælpe dig, bliver du nødt til at give mere detaljerede oplysninger. <br> Afklar venligst dine krav: En infrarød modtager, der kan styre en LED fra en generisk infrarød fjernbetjeningssender; Tryk én gang på fjernbetjeningen, og LED'en tændes. Slip fjernbetjeningen, og LED'en forbliver tændt. Tryk på fjernbetjeningen igen, og LED'en slukker. Slip fjernbetjeningen, og LED'en forbliver slukket. Med andre ord er omskiftningshandlingen en låst omskifter, den er ikke midlertidig. Der er intet krav om at bruge en bestemt tast på fjernbetjeningen: et tryk på en vilkårlig tast på fjernbetjeningen giver det samme resultat. Modtageren skal forsynes med 2 x 2032 batterier. <br> Er dette korrekt? <br> Andre designoplysninger påkrævet: <br> Hvilken type LED skal bruges (farve, fremadspænding, nominel drift og maksimal fremadgående strøm)? Hvad er målbatteriets levetid for modtageren? Inkluderer modtageren en tænd/sluk-knap? Er modtageren kun til indendørs brug? Hvor mange enheder har du tænkt dig at lave? <br> Bemærkninger: Valget af VS1838B til IR-modtageren kræver, at IR-fjernbetjeningen sender med en pulsmodtagelsesfrekvens på 38kHz. Andre enheder end dem, du har angivet, kan være bedre valg til dit projekt. <br> For anyone to try to help you, you will have to provide more detailed information. Please clarify your requirements: * An Infrared receiver that can control a LED from a generic Infrared remote control transmitter; * Press the remote once and the LED turns on. * Release the remote and the LED stays on. * Press the remote again and the LED turns off. * Release the remote and the LED stays off. * In other words, the switching action is a latched toggle, it is not momentary. * There is no requirement to use a specific key on the remote: pressing any key on the remote produces the same result. * The receiver is to be powered from 2 x 2032 batteries. * * Is this correct? * * Other design information required: * * What type of LED is to be used (colour, forward voltage, nominal operating and maximum forward current)? * What is the target battery life of the receiver? * Does the receiver include an on/off switch? * Is the receiver for indoor use only? * How many units do you intend to make? Notes: * The choice of VS1838B for the IR receiver requires that the IR remote control transmits at a pulse reception frequency of 38kHz. * Devices other than those you have listed may be better choices for your project.
