I have a mega Arduino attached to a esp-01 as follows
Arduino-------------esp-01
3v3
gnd------------------gnd
Tx-----------------Tx
Rx-----------------Rx
reset-gnd | en--gnd
|||||||||||||||||||||||||||||||| I00--3v3
||||||||||||||||||||||||||||||||reset-gnd(button)
#include <Ethernet.h>
#include <MySQL_Connection.h>
byte mac_addr[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
//3C-6A-A7-66-7F-10
IPAddress server_addr(127, 0, 0, 1); // IP of the MySQL *server* here
char user[] = "root"; // MySQL user login username
char password[] = "12345"; // MySQL user login password
EthernetClient client;
MySQL_Connection conn((Client *)&client);
void setup() {
Serial.begin(115200);
while (!Serial); // wait for serial port to connect
Ethernet.begin(mac_addr);
Serial.println("Connecting...");
if (conn.connect(server_addr, 3306, user, password)) {
delay(1000);
// You would add your code here to run a query once on startup.
}
else
Serial.println("Connection failed.");
conn.close();
}
void loop() {
}
I don’t have an Arduino Shield, or esp8266 adapter, so I can’t use the #include <Ethernet library. h>
someone on can help with the code?
