Arduino rtc DS3231, card reader, push buttons

Hello, I have the code and the circuit ready with this kind of functionality. Relevant Skills and Experience arduino embedded systems Proposed Milestones $10 USD - complete working code and circuit diagram

I agree. I already solve very similar task. I ll do it very fast. Relevant Skills and Experience Arduino 5 years Proposed Milestones $10 USD - Arduino code (sketch)

will use arduino board connected with DS3231 and Microsd card. Relevant Skills and Experience Have worked on number of projects based on Arduino ,Esp8266, Raspberry Pi, Beagle bone . Stay tuned, I'm still working on this proposal.

AGREE Hello brother, I can do it for you and simulate it on Proteus as well. It is straight forward and shall supply it even with fritzing diagram. Thanks

I will do it for you. in mentioned budget. I made project with SD card as well as ds3231. but not combain. but had experience with rtc module ds1307 and SD card. I am agree to make this project on my mentioned budget.

I have already worked on this. The code of this project or whatever the documentation required is ready with me. Relevant Skills and Experience I am a pro in Arduino, Embedded Linux Programming, RaspberryPI, Shell Scripting, Python, Image Processing, OpenCV, MATLAB, node-MCU, IOT, ESP8266, QT & circuit designing. Proposed Milestones $10 USD - To start the project, defining objectives and all the task with timeline. $5 USD - After completion of 100% project and tested over 1000 times. Additional Services Offered $10 USD - The price will be depends on the complexity of the task. Can we start the work? I will be happy to work with you.

I have done so many data logging projects as part of other big projects. Like data logging of ph, dissolved oxygen like that with respect to time.. Your project, as per the description above is very simple.. I can complete it in 1 day. I placed 2 days in bid because usually I'll take 1 day as a make-up day if i met any issues. Simple circuitry, i ll give you a detailed report about circuit diagram and program.

Hi, I can complete this for you at the earliest possible. I have all the required parts, the ds3231, sdcard shield and the controller. Will provide you with complete working code and circuit diagram. Relevant Skills and Experience arduino, rtc, sd card Proposed Milestones $25 USD - complete project

Hi I am an engineer and and arduino expert . let me know the details please

Agree Stay tuned, I'm still working on this proposal.

Acepto, solo una observacion freelance te va un cobrar minimo 10 espero eso lo tengas presente saludos Habilidades y experiencia relevante Arduino, ocupado DS1307, DS1302, ds3231, y algunos otros dispositivos, Htos propuestos $5 USD - Device connection, $5 USD - save to memory

AGREE to 5$ Relevant Skills and Experience I have already worked on the same project for my college and have the source code, so i'll be able to simply deliver it to you in one day's time! Proposed Milestones $10 USD - For final delivery of project

AGREE Relevant Skills and Experience I have made many Arduino project including data logging with SD cards Proposed Milestones $10 USD - Main concept realisation $5 USD - project perfection $5 USD - Extra fitures I am located in Latvia, so I hope that isn't a problem and I can work from here.
