Write some Arduino code

$30-250 USD

$30-250 USD

Paid on delivery
I would like to combine 2 pre written codes by Adafruit and expand them for further features. One is a Arduino master writer RFID, which needs to send the Card details through i2c to the Arduino Slave writer The second would be a Adafruit data logger with temperature and light reading, this code has a fault which does not print the correct temperature and light reading. [login to view URL] With this datalogger it needs to be connected with i2c to become a slave writer It also requires 6 extra pin states, when switched to high, it will set a time, date, temp, light and pin recored to SD If card is detected it will a write card number with a time, date, temp and light stamp and Record to SD Card.

Hi, I have experience for 15+ years in electronics/embedded development. I have several years of advanced AVR/arduino development, including library development from scratch. Practically all Arduino AVR boards used, like: 2009, 2010, UNO, MEGA, NANO, MICRO, MINI, etc. Several shields used like Ethernet (W5100, ENC28J60, etc.) with various IP protocols implementation, various graphical TFTs with and without touchscreen and various BUS types (parallel, SPI, I2C, etc.), all kinds of sensors and buses, serial and parallel memories, etc. Have also worked in projects before with RFID modules (13.56 MHz, NFC, Mifare, 125kHz, PN532 chip, etc.), as well as adafruit datalogger shields or similar (DS1307 RTC and SD card interface). Just not sure if I have worked and have the light and temperature sensors you are using in your project, but will not have problems in that part. Regarding I2C communications, I have made at least 2 projects before with arduinos (among other microcontrollers) one acting as a master and others as slave devices (addressable sensor devices). If you are interested in my bid, please let me know some more details about your project and I'll be able to answer you back telling if I'm up to the task or not. Feel free to contact me. Regards, Carlos.

Hi, I'm an electronic engineer with more than 4 years of experience of Arduino programming. I read your project description and it got me interested of the project as I have previously used RFID readers with Arduino as well as SD cards as data loggers. I'm not sure of your requirement of Arduino Master and Arduino slave as data logger as we can occupy SD card module with the same Arduino as Card occupies. As I know RFID readers will use SPI pins of arduino as well as SD card. But SPI can handle both of these well. So I believe we can use one Arduino for the process. Please correct me if your requirement is different. I can try to understand your temp sensor code and correct. That should be possible. I have worked with time data saving function on SD previously, so I can handle that part well. I would like to know more information on how to set data and time initially and looking forward to hear from you Thank you Anusha
