save input data from 8 bit 4x4 matrix keypad with time stamp - open to bidding

Very easy project for us.. See my profile and feedbacks. We are very much experienced in keypad and data logging projects. I can design the device to log data and download data via USB or bluetooth to smartphone. We can provide PC application/ smartphone application to download and view the timestamped data.

Dear sir, I can create for you a design that save data from 4x4 keypad on sd card with time stamp also i can add any extra features u want

hi, i am an electrical engineer. i have expertise in embedded system design and Matlab.i can help you with this project. Please check my profile for my previous work experiences. let me know if you are interested in the bid so we can discuss the details further. regards

i have this project with me .. scans the 4x4 keypad and a rtc real time clock is attached with it. when a key is pressed it saved it in eeprom . u can download this data whenever u want with the help of a computer application .

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. I can help you with your deal and since im new one here I can do it cheaper then anybody. How many stamps do you need? Battery or acc? Charger onboard to charge from usb if acc? I can do either homemade pcb, or order manufacture and you get cute green pcb with mask.

Hello. I can develop schematic, pcb, firmware and pc software for this project. Device can be connected via usb to read logfile. I have the similar projects so I also will be able to test your device in real hw. Best Regards Anton.

Hi, We are a team of electronics&embedded engineer with more than 10 years of experience in designing and developing various digital and embedded systems... We have done a lot of projects in Arduino. Also we conduct many workshops on Arduino..As a part of our training program we developed Arduino/PIC based Programming boards and driver boards for sensors. Since we help engineering students to complete their academic projects, we have experienced with a lot of sensors, components, PCBs etc. So we can assure you that this project can be done 100%perfect....:-) Please check our completed projects...:-) Kindly let us know more details about this project and we can complete it together...:-) Thank You

i am an engineer that works already on that career on embedded systems company at my country it will be easy and i will simulate the circuit online for you and i can make a video and send it to you you will be provided with the hardware design and the source code when the project complete

I have created several projects on arduinos in the past. Where exactly will the storage be for this project?
