help
sorry i wanna ask
how to save data logger with sd card module in arduino? and what i must add to my sketch?
my project for my final test, it is control lamp with esp8266, but have no data log, i wanna add data log with sd card module, thanks
my sketch
#include
#define DEBUG true
SoftwareSerial esp8266(6,7); // tx 6, rx 7
void setup()
{
Serial.begin(9600);
esp8266.begin(9600); // your esp’s baud rate might be different

digitalWrite(10,HIGH);
pinMode(11,OUTPUT);
digitalWrite(11,HIGH);
pinMode(12,OUTPUT);
digitalWrite(12,HIGH);
pinMode(13,OUTPUT);
digitalWrite(13,HIGH);
