I have expertise over all communication protocols of Microcontroller: - SPI (Master/Slave) - UART - USART - I2C (Master/Slave). - Ethernet - Wifi - Bluetooth etc.. I am expert in interfacing sensor modules with microcontroller. I believe in providing superb quality provided that the deadlines are met. Moreover, during the course of my project I would keep you updated regarding the status. Looking forward to hear from you Regards Khawaja Muhammad Abdur Rehman

Hello, I have many experience with arduino and robotics. Please view my portfolio for more information. As I understood, the required task can be completed with in a day, if you need only the source code. An it do not cost more than $100. I was going to bid it for $57 and I like to complete this project for that amount ( source code + circuit diagram ). Do you need a PCB as well? Project approach: 1. Use an led driver ic to drive all the leds and pwm out pin from arduino to control the brightness. 2. Use an IR led and an IR sensor to detect the motion. IR sensor output a digital puls if it did not detected an IR light. IR led need to drive in 40kHz. 3. Connect the IR sensor out as an external interrupt to arudino. 4. When interrupted, set the pwm frequency to 100%. Need to discuss more on this project for some clarifications. Thanks, Kasun

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

Dear Employer, I have 5 year experience in microcontroller based sensor system design and PCB design. I have been involved in prototyping research ideas. I have quite a good expedience with Arduino boards, Atmel 8 to 32 bit controllers, Atmel ARM controllers and wireless sensor networks with ZigBEE, IEE802.15.4 and ANT. I have designed PCBs with Eagle Layout Editor and PADS by mentor graphics. You are most welcome to contact me in case of any further question about my qualifications, similar projects I have been involved in or to get my insight about your project. Best Regards,

Hi. I am a professional electronics Engineer having expertise in Arduino and in Electronics Circuits. Contact me and provide me the details.

I could help you. . . . .

Hello, My name is Victor I am engineer with 4 years of experience working with Arduino. As you can see in my review I have the skills and the experience to help you with your problem. To solve your problem we can use a IR led and IR detector to sense the presence of the vehicle at the beginning of the track, and based of that we can control the intensity of all the other leds. For that budget I will provide you the Code and the Circuit to run the project. If you are interested in my help I will be happy to help you. Regards! Victor

Hi There, Reading through your requirements caught my attention as I have a solution in mind. A few questions and comments though, 1) You have a total of 12 LED's that need brightness control. However, the Arduino UNO you have has 6 PWM pins only. That means only 6 LEDs can be controlled INDIVIDUALLY. However, individual control is not necessary, then we could combine a number of LED's on one PWM pin. 2) I suppose he car is only travelling in one direction from LED 1/7 going to LED 6/12 right? By the way, I am an electronics engineer with 11 years experience working with microcontrollers, almost 4 years of those I've spent on Arduino related projects. (I've spent 5 years of those in Singapore :) ) thanks, Christian

The 30% brightness will be achieved through PWM so will the 100% brightness. there are 5 PWM pins so we can make 2 LEDs in parallel with each other. LED1 and LED7 will be the IR Transmitter and Reciever. I will make the circuit diagram in proteus and show you. Although I have written 10 days in completion it will be done much sooner. Please view my profile and see that standard of my work if interested hit me up!

Hello, You just need to specify the vehicle size and have one IR source in front of the IR receiver at the opposite side of the vehicle. It will be also necessary to build an amplifier for the IR receiver. The rest is PWM coding task. So, what is the size of the vehicle or the distance between the IR source and the sensor? Thanks, Ashot

Arduino doesn't have 10 analog inputs. So you need also summer opamp circuit or multiplexer before analog inputs. I could send you circuit schemtic and code with explanations in one day. Best regards,

i can do your project but what arduino module are you using like their are many i.e arduino nano , arduino uno etc for further details you can check our projects portfolio .

I am an enthusiastic, 3rd year student in the Netherlands and I have worked with this micro controller on a daily basis for more than one year. The profile I am studying is called Advanced Sensor Applications, therefore I have some experience with sensors as well. Your project does not look that complicated and my knowledge will definitely be sufficient to achieve its purposes. I have some questions regarding the IR sensors. How many of them are they? What model? How do you want to place them? Regarding the control of the LEDs, I will use a technique called Charlieplexing, where you can use just 4 pins of the Arduino Uno to control 12 LEDs. I have recently done a similar project at school using this technique, where I had to control 20 leds from 5 pins. I would be more than glad to show you a short video of how I am controlling them individually. I would also have some questions regarding the behavior of the whole system, therefore I am looking forward to hearing from you as soon as possible.

Ok we can do this project by using an IR sensor at LED 1 and 7. Using pulse width modulation to control the brightness of the LEDs all together we can have 30% brightness of LEDS at the beginning. Once motion is detected the LED's light at 100%. IF it is a demonstration is required It can be done on a piece of wood the size of a laptop. The LEDs can be arranged and wired to the arduino.

I have done so many projects on arduino . participated many local competitions . this projects seems very interesting to me .
