bm muna lupit tong topic nato ah
ESP8266 nagamit ko na to para sa IOT via Alexa,
ecoconnect pa po ba to sa modem natin ?
 
ito yata yung kaparehas ng nabili ko piso wifi, mikrotkek yung mainboard, may lcd screen sya, pag hulog ng barya,pipindot sa button,lalabas yung 6 digit na number,yun yung password na ittype dun sa portal,connected na sila, 1 week ago pina configure ko sa seller kasi gusto ko ibahin yung time, yung software na gamit niya is WINBOX at THE USERMAN, tapos nya mag generate ng mga codes, i copy-paste lang pala sa SDcard yung DOX files,at yun may auto generate password na, punto ko dito kung makabuo kayo at same ng sakin, ibibgay ko yung file na pang SD para di na kayo ma hirapan mag program,kasi copy/paste lang pala. at ito yung time ng vendo ko 1-10minutes 5-1hour 10-2hours 20-12hours 50-2days dati 20-4hours, nilagyan ko promo kasi ganito, imbes na maghulog sila ng 10, eh ginagawa nila 20 kasi 12hours, halos lahat 20 na hinuhulog, sa lima ka tao may 100 ako per day, 3k monthly,sobra sobra na yun pambayad sa bill ng net at kuryente,sakin kasi sideline lang dito sa shop ko, eh kung lumagpas pa dun yung profit e mas maganda

Boss
ito ba ang code on demand type?
 
unfinished user / code generator
need to incorporate sa previous post

ang balak ko kasi arduino na mag auto config nya un mikrotik, the arduino can then send commands sa mk to create the user profile, timelimit according sa ihulog na amount. tapos auto delete na rin

meron nang gumagawa nito ala lang mag share ng source code, im just sharing what i have learned, kaya wag nyo akong husgahan kng mali ginagawa ko

kung meron kayo source code ng arduino piso vendo on demand pa share naman dyan

arduino SD card read/write sunod
 
Last edited:
need to modify so that you can read/write on the sd card para kng mag crash un system meron k back up record.

again ngayon palang ako gagawa ng piso wifi , eto lng nasearch ko n mga kailangan para makabuo





Code
The code below is configured for use with an Ethernet shield, which has an onboard SD slot. In the setup(), we call SD.begin(), naming pin 4 as the CS pin. This pin varies depending on the make of shield or board you are using.

In setup(), create a new file with SD.open() named "test.txt". FILE_WRITE enables read and write access to the file, starting at the end. If a file "test.txt" was already on the card, that file would be opened.

Name the instance of the opened file "myFile".

Once opened, use myFile.println() to write a string to the card, followed by a carriage return. Once the content is written, close the file.

Again, open the file with SD.open(). Once opened, ask the Arduino to read the contents of the file with SD.read() and send them over the serial port. After all the contents of the file are read, close the file with SD.close().

/*
SD card read/write

This example shows how to read and write data to and from an SD card file
The circuit:
SD card attached to SPI bus as follows:
** MOSI - pin 11
** MISO - pin 12
** CLK - pin 13
** CS - pin 4 (for MKRZero SD: SDCARD_SS_PIN)

created Nov 2010
by David A. Mellis
modified 9 Apr 2012
by Tom Igoe

This example code is in the public domain.

File myFile;

// Open serial communications and wait for port to open:
Serial.begin(9600);

}


Serial.print("Initializing SD card...");

if (!SD.begin(4)) {
Serial.println("initialization failed!");
while (1);
}
Serial.println("initialization done.");

// open the file. note that only one file can be open at a time,
// so you have to close this one before opening another.
myFile = SD.open("test.txt", FILE_WRITE);

// if the file opened okay, write to it:
if (myFile) {
Serial.print("Writing to test.txt...");
myFile.println("testing 1, 2, 3.");
// close the file:
myFile.close();
Serial.println("done.");
} else {
// if the file didn't open, print an error:
