Arduino Sketch Below is the entire tutorial code, scan over it and see if you understand it before I dive into what each section does. There are three address pins in AT24C02 for selecting a particular chip. Datashert to move on to software! The next three bits A2,A1,A0 are the important bits that we can change so lets look at the simple table below to see what address the chip will have depending on datasheef we set these pins to.

This last bit is 1 for write and 0 for read operation. Similarly for read operation the device address to be sent is 0xA0 For more details on different operations and addressing, refer interfacing 24C02 with The first argument is the address of the device you want to write to, in our case we only have one device disk1 so we pass this on. Interface SD Card with Arduino.

Finally a stop condition is provided. To illustrate this lets follow the steps below.

Next we do a bitwise AND to get just the last eight bits. Next, the byte or page address is sent followed by the data byte. The first send function takes the eeaddress and shifts the bits to the right by eight which moves the higher end of the 16 24cs2wp address down to the lower eight 2cd2wp.

Before we get into the software part lets hook up the 24LC chip up to our Arduino. When data is to be read or write, first a start condition is created followed by device address, byte address and the data itself.

Next lets go ahead and connect the data pins to the Arduino board. The next function requestFrom sends the command to that chip to start sending the data at the address we set above. There are 32 x 8 words each of one byte. datashheet

This is a little confusing at first so lets look at the figure below to explain the address in a little more detail. Interface GPS with Arduino. The next argument is the address on the eeprom you want to write to and as stated above can be between 0 and 32, We first call the Wire.

Then connect the SCL pin 6 to pin 5 on the Arduino. This means our 24LC chip gets the address and then which tells it to store the next byte in address location 20, Since our eeprom chip has 32, address locations we are using two bytes 16 bits to store the address but we can only send one byte at datasheer time so we have to split it up.

Choosing Motor For Robots. Supply voltage; 5V up to 5. This tutorial was dtaasheet posted on the 10kohms. The WP pin stands for write-protected and this allows you to control if data can be written to the eeprom or not. Choosing Battery datashset Robots. The data is read or written between the start and stop conditions on every transition of SCL from high to low. Finally we have to pass along the byte we want to store. This allows the chip time to complete the write operation, without this if you try to do sequential writes weird things might happen.

Virgin Galactic — Commercial Space Flight. This is written for Arduino versions before 1. For more information please read http: With the address pins connected the hardware part of this tutorial is complete and every pin of the 24LC should be connected to either Vcc, GND or the Arduino.
