Hi Folks, today i am writing an article and this is belong to my video tutorial OLED Display with Arduino on youtube. If this article help you please subscribe to my youtube channel and like our facebook page.
This article and video will teach you how to display the characters on OLED Display with an Arduino. And you can find the Circuit Diagram and Arduino code below of the page.
For this Arduino tutorial I am using.
Video for a descriptive step-by-step guide
Arduino Scanner Code to check I2C device
/*
CircuitMagic.com
*/
#include <Wire.h>
void setup()
{
Wire.begin();
Serial.begin(9600);
Serial.println("\nI2C Scanner");
}
void loop()
{
byte error, address;
int nDevices;
Serial.println("Scanning...");
nDevices = 0;
for(address = 1; address < 127; address++ )
{
// The i2c_scanner uses the return value of
// the Write.endTransmisstion to see if
// a device did acknowledge to the address.
Wire.beginTransmission(address);
error = Wire.endTransmission();
if (error == 0)
{
Serial.print("I2C device found at address 0x");
if (address<16)
Serial.print("0");
Serial.print(address,HEX);
Serial.println(" !");
nDevices++;
}
else if (error==4)
{
Serial.print("Unknow error at address 0x");
if (address<16)
Serial.print("0");
Serial.println(address,HEX);
}
}
if (nDevices == 0)
Serial.println("No I2C devices found\n");
else
Serial.println("done\n");
delay(5000); // wait 5 seconds for next scan
}
iam getting an error in the code what should i do.Iam getting it as wire.begin(); was not declared in the scope
dont make full upload the proper code #incloude wire . h
#include is missing in the above code
#include “Wire.h”
#include “Wire.h”
Add Wire.h
