For our multi-stage mountain bike races, there is a need for competitors to stop at a stop sign on the course. Rather than have a volunteer stand at the stop sign to check that a competitor comes to a stop, it might be easier to develop an electronic solution. This stopping is necessary to ensure all competitors start from the same location. This electronic solution primarily needs to: - measure that a rider is less than 100cm from the sensor (stop sign) - measure that a rider holds their position for 5 seconds (i.e. their distance does not decrease more than 10cm for 5 seconds) - confirmation by a green LED that if a rider has held their position for 5 seconds, they are permitted to proceed - the solution determines that the rider has proceeded (eg their distance becomes say 30cms or less?) or even another ultrasonic sensor aimed perpendicular to the race track to act as a 'virtual breaker beam' and if this sensor detects movement across it, then a rider has proceeded. - if a rider proceeds before the green LED confirmation, a photo is taken and uploaded to the cloud for access at the race village so we can apply a time penalty to their results - once the above has occurred, an LED turns on after 30 seconds - one the above has occurred, an LED turns on after 60 seconds Their might be a little 'trial and error' of the provided times but I assume the coding could easily be modified after a testing phase. Hardware: - I have several Arduino boards and batteries from an unfinished project that I could use and we would need to add the ultrasonic sensors and camera. However, it may be easier if we used cheap mobile phones to act as the platform with their onboard camera and internet connectivity but I am guided by your advice. If mobile phone based, the green LED could simply be the screen turning green and then a 60second timer shown on screen. - The most affordable sensors I have found would be these [login to view URL] and picture attached - but I am open to suggestions. If we use a mobile phone platform, these sensors may somehow have to be connected via bluetooth or usb? However, these units will need to be on for a minimum of 5 hours I am looking for someone to offer a good solution and other ideas are welcome from my suggestions above. I will need to make 8 of these units so construction time is important followed by cost. It is also important to identify at which stop sign the photo was taken (which could be just code based and added to the filename of the photo eg [login to view URL]).

Hello I have got your job posting “Measure if an approaching object stops briefly before a 'line' and if not, take a photo and upload for remote viewing” and I am very much interested to work in your project. I am a circuit designer and have more than 5 years experience of working with the Analog/Digital Electronics embedded systems(Arduino,Rasberry pi ,ARM processors ,PIC microcontrollers,Wireless boards,TFT Touch Displays,All types of sensors and actuators). i have done tons of similar projects So, I think you’ll find, I have the skills you’re looking for. For more on my skills and successfully finished projects, please have a look on my Profile and Portfolio. I have all the components available here with me so i will develop a working prototype according to your specifications and then send you the code and schematics so things will work for sure.I will remotely guide you and help you build the system on your side. I am always available on Email and Skype. Please have a voice or video chat if necessary. I shall be available round the clock and able to start your project as soon as possible according to you. Thank you for your consideration, Best Regards, Haseeb Shafqat

Hello there! I'm almost graduating from Mechatronics Engineering. I've worked with plenty of Arduino projects, one of them was building a little electric car that had no pilot, it ran on it's own using optical and sonic sensors. I believe I have the skill and the experience to get the job done. Though I have questions, have you used these sonic sensors before? Sometimes they are tricky to use, specially outdoors. Have you done any tests? Did it work detecting the rider on the bike? A bike has many empty spaces, the sonic waves might just pass through empty spaces (like the wheel) and not detect the rider even if he's there. It all depends how you're going to install it. Or we might use sensors that detect the metal of the bike, we'll have to investigate this more. How are you going to install the sensors? Fixation and wiring could cause some problems, specially outdoor. Are you using one arduino board for each stop sign? Are you using phones to take pictures and upload them? If yes, what kind of sensors these phones have (some phones have really bad sensors)? Anyway, looking forward to helping you and doing a good job. Take care.

Buenas tardes, en cuestión a su proyecto yo le puedo ofrecer una placa donde pueda colocar el sensor de distancia, el arduino (favor de definirme el modelo del arduino) y un transmisor de bluetooth que este enviando datos al teléfono, solo pediría información de las baterías para ver si puedan durara las 5 horas mínimas. En cuestión a lo que menciona a de un aplicación del teléfono móvil, también puedo hacer esa aplicación, donde el teléfono pueda tomar la foto, poner las pantalla roja o verde o del color que quiera y poner su temporizador, todo esto mediante una interfaz bluetooth. El tiempo del proyecto declare 10 días, pero se puede entender a 15 días, debido a tiempos e fabricación y pruebas
