This is a simple project. I need an arduino to monitor 2 light towers.
I have already set up an arduino Due connected to the signal tower as shown in the attached image.
Here is a summary of how it works in case the picture isnt clear.
Each light tower has 3 24v lamps.
These lamps are turned on and off externally.
I have tapped into each lamp's power, and each wire runs to a 24v reed relay.
Each relay pulls down a pin on the arduino.
I have also attached an ethernet module as shown here:
[login to view URL]
A lamp can be in one of 3 states: on, off, or flashing.
Each time the state of any single lamp changes, the tower's states needs to be sent to the server.
(ex. http://server01/[login to view URL] 0 is off, 2 is flashing, 1 is on)
This should happen as the unit turns on as well.
If flashing, it would be at a rate of two flashes per second (at 500ms intervals).
I had tried to write the code myself using interrupts to monitor these pins but I keep getting strange results as soon as I wanted to monitor more than one pin.
My interrupt routine would check if the last flash was between 400ms and 600ms ago. If it was, it would set the state to 2 (flashing) and a flag so the loop will post to the server.
I also set a flag so that the loop will check back in 600ms. If (now - lastcheck) > 600. we would catch a 'solid on' or 'solid off' state. This wouldn't trigger if it was flashing, because every ~500ms 'lastcheck' would be reset.
I have attached my sketch (very inefficiently written) for reference.
For testing, just set up another arduino as a test flasher or get a flashing relay.
Anyway, this is very basic and should be easy for someone who has done this before.
The only deliverable here is a sketch/libraries etc. I already have the boards hooked up.
Thanks! I need this urgently so please only quote if you have time this week or early next week.
Hello Sir,
We have completed several Arduino projects on Freelancer.com, So we can help you to do your required sensing part completely.
Please see our profile and past feedbacks to understand our capability.
We will available this week for your project.
Best Regards,
Lasantha Prasad
I can do this project as I have 12 years of design and development experience. My deliverables shall be following:
1. requirement specification document.
2. Schematics
3. simulation
4. source code delivery.
Thanks,
Faisal.
Hi there I can do it.
Ive done a lot of similar projects before. Im a telecommuncation engineer. Ive studied a lot of subjects of embbebded systems (watchdog, scheduling, interrupts, timers, etc).
I own hardware to build a prototype here too.
If you can test code once per day or so i can finish your project soon.
Let me know if you are interested in my services.
Can help... I am an Expert... Please check the past projects I have handled and check my reviews for what employers have to say about my work... Can start right now...
I have working with Arduino projects the last three years. The type of work described by you is within my skills. I am very interested to assist you in your development needs.
Very easy project. I will be glad to help! I am free today, so if you award me the project within today I will probably make it work in about 24 hrs. As I understand from the code and description, you need just the "detect blink" code to work and to write to the serial port. You will add the code to connect to the server.

Hello:
I'm a Mechatronics Technologist with a wide experience working with microcontrollers such as PIC, ARDUINO (AVR) and FREESCALE, feel free to contact me to talk about the project and optimize it.
I believe I can solve your problem with timing and interrupts. I think this can be done by attaching interrupts, catching an interrupt, disable interrupts while processing, process pulses with pulsein (detect pulse or continuous signal), report data to server, and re-enable interrupts. The only potential drawback of this method is that while data is being processed and sent changes will not reported. I do not think that will be an issue since the state of the lights should not be changing faster than every 10sec.
I can start next week. Let me know if you have any questions or concerns.
Hello
I can do this work as per requirement . I am Embedded programmer. I can control it form Ethernet port and send the required information to the server through URL
I can start the today and finish asap.

Hi,
I am an Expert in Embedded Systems. I have experience with various microcontrollers including ARM, AVR ,PIC, Arduino, 8051 etc. I have extensive experince with Arduino I can do this task for you.
(update)
Okay so I have read the update about your code I will update my bid accordingly.
Regards
Hello, I have done similar projects to what you what to do. I have an Arduino Mega and a W5100 shield so I can test the code, just give me the URL of your server and I could send the values. I can work in your project as soon as possible and finish it in 2-3 days.
Hi,
I can help you fix problems with your code and complete the project with requirements mentioned below.
Experienced in Arduino programming, also have an Arduino DUE with me, so that testing would be done with an ease.
Also would make some adjustments to code currently you have to make it more efficient.
Hope we can work together. I also posses an different account describing about my previous experience than this site, please let me know if you wish to see it.
Regards,
Vikas
Hello, I am working as an embedded engineer in India. I have experience working on C, Micro controllers, electronics. So I hope I can help you with your project. I need maximum of 12 days for completing & this is my worse case estimation. I am sure I can deliver you the project within 8 to 10 days. Waiting for a positive reply from you. Thanks - gtbtech
