Hi Klauss,
thank you for your work.
just a reminder.
so ac must be converted to dc then supply design should be adjusted for dc
in ac systems ac converters/ac inverters/ac choppers should be used for required signal

hi,
i want to use a wi-fi connection between my ics and pc but I don't know any ics .i want to build a board for wi-fi.i just seen esp8266 but I may need measure for long distances.
please advise your projects and your thoughts
thanks
the answer is you can't.Altium only supports one file per project for pcb.You can create many documents by adding schematic but it will confuse to use which is best
hi again,
i dont advise you to adjust the gnd.cause many applications use the 2.pin as gnd not adj.
i advise you to build a voltage divider
try to use these systems with voltage dividers at the end of the circuit
buying a smps can also be a cure but you wont see many appliences as you try to...
if you can find a computer power supply that has rail like the old ones it is very usefull for the projects it has +5v output and +12v output.
also designing usb chargers or directly from transformer with pcb is very usefull with lmXX series
2.5ms is not enough,try to code for lcd initilalization time(about 100ms) and then pls check if the wiring is not reverse
i mean some lcd are starting from 14.ground to 1 and so on...
but most of them have backlight at 15 and 16
working lcd contrast code
did you see the dark lcd characters if not please check your wiring.
and if your controller of your lcd is overheating stop the power supply because it may damage your lcd.
