Arduino Project using Interrupts

Hello, I have a good experience with Arduino (Uno with GSM interface) and have used Software UART. The software UART has similar functionality as you mentioned - that is the data edges trigger interrput and data is read by the program. Unfortunately the codes that I did for Arduino was for some customer and unable to put the code here. One of the project was for uploading measurement data on GPRS network to a server. I wish to know what is the minimum period to be measured. Based on that appropriate solution can be determined. Please let me know more details. Thanks Vinod

hi, i am an electrical engineer. i have expertise in embedded system design.i can help you with this project.

Hello Sir, We have done several Electronic projects. Please see our profile for present and past projects. Please provide your flow diagrams to inspect. Thank you very much Lasantha Prasad

Hello, I can provide the sketch. Since it involves the triggering of an interrupt and then Time and date stamping. I can provide sample of complex codes that i wrote. please feel free to contact. Reagards, Shahbaz.

Hi, I have read and understand your proposal. I have relevant experience with Arduino and I am ready to discuss the details.

Tell me more please. . . .

Hi, I have experience with Arduino and I can do your project. Please see in my portfolio - Arduino. If need I can send to you more Arduino examples developed from me. Regards, Slavi.

Greetings. My name is Jeremy Trammell and I represent a group of designers and developers in Portland, Oregon. We have extensive experience with the Arduino platform (you can see a couple of examples of our recent projects in our work history on this website, but obviously we can't send you the projects we've worked on as they are not ours to distribute) and would be happy to assist you with your project. Unless this series of codes is quite large, we should be able to have a completed project ready for you within a few days.

hi , plz messga me about the details .... thanx ............... waiting for your response ....regards

Hi. I'm an experienced arduino programmer. I've worked on something similar to your project. I worked on a project that involved using interrupts to find the time period of a pulse emitted by a distance sensor. Also, I understand the complexity of the project - code sequences are hard to detect due to the small variations in them. In addition, I own an Arduino Mega 2560 R3. Feel free to contact me. Thanks.

I have working with Arduino projects the last four years. The type of work described by you is within my skills. I am very interested to assist you in your development needs.

Hi, I've worked on several Arduino projects, including a quadrotor. I am pretty sure I'll be able to build a device based on the interrupts you want. I am attaching a very simple code I did long back, which involved simple timing and Relays. (It may be terminated because of the character limit on this proposal) #define TWO_HOURS 7200000 //use for final running // #define TWO_HOURS 11999 //use for testing const int led = 13; const int relay1 = 4; const int relay2 = 5; const int relay3 = 6; const int relay4 = 7; unsigned long count = 0; void wait_two_hours() { while((millis() - count) < TWO_HOURS) { delay(4000); } count = millis(); return; } // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); pinMode(relay1, OUTPUT); pinMode(relay2, OUTPUT); pinMode(relay3, OUTPUT); pinMode(relay4, OUTPUT); digitalWrite(relay1 , LOW); digitalWrite(relay2 , LOW); digitalWrite(relay3 , LOW); digitalWrite(relay4 , LOW); count = millis(); } // the loop routine runs over and over again forever: void loop() { digitalWrite(led, HIGH); // turn the LED on digitalWrite(relay1, HIGH); digitalWrite(relay2, HIGH); delay(5000); digitalWrite(relay2, LOW); delay(2000); digitalWrite(relay3, HIGH); delay(5000); digitalWrite(relay3, LOW); delay(3000);

Hi, I have experience in the design of embedded systems and I had used arduino in some projects before. I must confess that I developed only a few using arduino itself but I had used AVR a lot. Few examples of my work: - Magnetometer switch: State machine based design that check the reading of two magnetometers and act if find a difference. The system was designed to sleep between reading and wake up on watchdog. Developed using arduino - Custom PLC - Programmable logic controller with FreeRTOS to controll a huge vehicle. The main processor was an arm cortex-m3. - Serial(RS232) to 802.15.4 - AVR based communication module that act as a bridge between several RS232 based design. Feel free to ask any questions or doubts about my previous experience or about some aspect of your present task. Best regards Euripedes

FREE... I am a new freelancer.A mechatronics engineering student and an arduino enthusiast. New to bidding. However can you give me your project document so I can try doing it as practice for my arduino skills. Dont chose me for the bid but just give your project. Ill do it without a time frame or requiring anything from you. If I happen to finish it in time, I will give you the system for free unless you wanna reward me. If I fail,well I will thank you for sharing you project idea with me.I want to be good in arduino. Hope you understand. Thank you.

Hi. I want to know for what type of Arduino. I've worked with Arduino at my bachelor degree with interrupts, switches, LCD, brushless motor, sensors(current, water, optic). So I will wait your response if you will pick me. Have a nice day.
