    Control a switch by microcontroller 16F877a

    Thank you for your replay. wwfeldman yes the simulation is working perfectly fine. Klaus, thank you for the valuable informations. I will stop asking questions in here. Just one final question, do you think that since this is on battery, I can just use a mosfet instead of a relay to avoid the...

    Control a switch by microcontroller 16F877a

    Thank you Klaus and baileychic for your reply. Just out of curiosity, why the values of the capacitors of the XTAL should be smaller ? and indeed, I should've add the resistors for current limitation. As for the relay coil current, I have a 5 volt rating and the coil resistance is 69Ω so the...

    Control a switch by microcontroller 16F877a

    Hello again, as for what u've told me to do, here is where Im at for now : the simulation is working, but I don't know if it's going to work perfectly in real life. So the Powerbank voltage is 3.7V, and the phone draw a current of 1.5A max - as for the transistor, I choosed BC547. - a 5V...

    Control a switch by microcontroller 16F877a

    Thank you Klaus for your reply. the reason I posted this is to get some help, to discuss if what Im doing is right or not, or if there is a better way, to get opinions and help of other people with much more expertise than me since Im kinda new to this. and yes it took me sometime to know that I...

    Control a switch by microcontroller 16F877a

    Hello everyone, I have this project where I should put a switch between a powerbank and a phone, and I should be able to control it by a microcontroller. So I found that a reed relay and a transistor is what I need but don"t have any refrences or idea of how to do it. So any help would be very...
