(M) is from the keyboard, the relay i use is the songle 5v (without any pcb), have not figured what capacitor i use yet.
This thing is designed to receive and send data from the (M) either using usb-c or with bluetooth and get power from usb-c or from lithium polymer battery.
My question is, will this work ?. Because, i have a strange suspicion that the relay won't work properly in parallel.....
A 6 pin button switch. M for pin that come out of the keyboard, i guess i need an intrepreter to translate that, any suggestion to what chip/ic/or device should i use for that ?
Can you give me link for technical book or documentation on how electronics component work and behave ? Google is not very kind in this kind of subject.... I will be gratefull if you provide me with some material i can learn tho ! <3
I decided to go with esp32-S2 because it seems to have internal usb controller build in them that i can use for this (also, it's general purpose, so i can always scrap it for other project if somehow it didn't work), still are confused on how relay behave on parallel or methods to isolate it from...... Burning..... i guess xp.
Holy, i would've shorted all the relay if i continue with my current design. With my current knowledge, i need to put them on series because i don't need the immediate property (and the problem that parallel design brings) Thank you for your knowledge great sir ! <3
*Edit : i also don't know that relay stores energy.....
*Edit 2 : i order some beefy diode in case of the current surge becoming problematic, i will experiment a little before putting it to work xp.
Sadly no, it's standard usb-A 2.1 (that i'm gonna switch to usb-c (note : i know where to put the 5.1Kohm resistor, it should be ok), i ordered the esp32 to deal with that.
