Arduino circuit and programming for drive way traffic light.

As a solution for locating a difficult-to-find automotive noise, both while the car is stationary and while moving, I'm imagining a group of perhaps 6 identical Bluetooth-enabled X-Y-Z vibration sensors which can ALL be started up, connecte...smartphone, which I believe might not be able to receive 6 data streams at the same time. I'd to also rely on this freelance to identify the cheapest, most cost-effective sensor and Bluetooth components that can still perform a high-quality job as described. I'm open to whatever processor technology works well as the 'brains' of each of the remote Bluetooth/Vibration Sensor modules, thinking Arduino or Raspberry PI might be what the freelancer recommends, but am open of other technologies if the same functionality can...

Hi there, We are looking for someone who has experience building a wearable chest mounted heart rate monitor device, hopefully you will have the correct experience with sensors etc. But we will need to build the device close to pre-existing devices.

I am using an ultrasonic sensor and Arduino Uno. I want to allow the distances read by the sensor to translate to different notes. The serial will be converted to MIDI in Hairless MIDI.

Bonjour, je possède un Arduino Méga + Shield Ethernet avec du code Arduino qui importe les trames d'un onduleur photovoltaïque et je souhaite que ce code au lieu d'être envoyé sur un serveur Web que je ne possède pas, expédie les données au format MQTT vers Home assistant;

This project is about writing, reading and modify information on SDcard. Data is a message that we obtain from GPRS. You don't need to implement any code for GPRS but this aspect can be useful for you to understand why and how to write the data to sdcard. There are 2 files: "" and "" - In "" will be saved all sensors data durring the loop. We will have a header. A file as example will be provided. - In "" we write the messages when GPRS can't send it to server. If this file exist and GPRS can transmit, will take a message from this file and retransmit it. After message was retransmited, will be deleted it from the file. If the files reache more than 1Mb, create another file using the time as name. for example: (year-mont-day-hour-minut...

I have a Arduino code for a robot line follower. I need help fixing the code because it won’t work properly. Can you fix my code up and see what I’m doing wrong

...and need help with the electronics and software. We realize that this is a multi-faceted project so let us know in what capacity you can help us. The simple explanation of the product is it takes measurements from multiple sensors and based on those readings it turns on and off relays to control our machine. To expound on that simple description: We would like to have a microcontroller like an arduino nano 33 IoT plugged into a custom PCB. This PCB would house the relays and ports for the sensors to plug into along with a touch screen. On the software side we would like a gui on the touch screen to display status of the machine, allow the user to set the parameters for when relays turn on and off, and to provide a clean user interface. Along with what is mentioned above we woul...

Hello, I'm a startup founder and I need help for the programming of my prototype using an Arduino and the Blynk platform. This is more of a test than the real program but if everything goes well, bigger projects will come. Here's the routine of the program: 1. I press a switch button on Blynk. "if" loop detect the state change of the switch. relay change to "LOW" for the necessary time amount 4. After, the relay switch to "HIGH" and turn off the button in Blynk 5. Loop start over I've made a code but I keep getting an error and I can't fix it. I will share the code and the error code with the winning candidate.

...budget for this project is $30. Please DO NOT bid if you do not agree with the given amount, nor if you cannot bid for the project within this budget. Thanks! ============================================ Just for the sake of learning, I want a very basic Android App to - send the result of selecting some Gui options (see picture attached) in Json (Encrypted) format to a BLE device (it will be an Arduino ESP32, that will receive these data, decrypt it and do something with it, but it is real irrelevant for the App), and - displaying the response in a text box (the App will not do anything with it, but just displaying it), I will need the program to later check it and learn from it. I can already program in C# and i am used to DotNet Core 3.1., so it would be great if you could...

Water cooling of a solar panel by connecting a pump and temperature sensor to the panel. The pump is connected to a water tank, at the same time there is a temperature sensor connected to the panel to measure its temperature. When the temperature of the panel reaches to (example) 45C, the arduino gives an order to the pump to turn on for 10 minutes, in order to cool down the panel. I have a 150W pump (AC), arduino uno, rely and the caples. As well as al the water circulation (pipes, nozzles) I need someone to tell me which temperature sensor is appropriate to measure the surface temperature of the panel. And I need him to teach me how to connect the parts and gives me the code and make sure to run this project well. I haven’t work on any aurduino previously. Thank yo...

Soy Carlos, ingeniero mecánico tengo mi empleo de tiempo completo y en ratos libres hago mejoras a los autos. Esta ocasión utilice mi pickup para colocarle un estribo eléctrico que detecta cuando la puerta se abre y se extiende. Una vez cerrada la puerta el mecanismo se retrae y queda oculto en la carrocería del carro. Yo he programado con arduino el funcionamiento del dispositivo, las salidas de arduino van a 4 relevadores que funcionan como un puente H y a su vez van conectados a otros relevadores que direccionan electrónicamente la dirección del giro. Con unos sensores se mide el amperaje y cuando exceda un valor establecido detienen el movimiento de los motores en ambas direcciones. Tengo un mes utilizando el dispositivo con mi c...

We have a project, that is basically reading load cells, displaying them on an LCD screen, and saving the results along with the GPS values on a file every time...on a file every time it reboots, without overwriting in addition to showing and saving the results on the mobile phone. As showing in the attached files, the project has been done so far using load cells, LCD screen, GPS module, SD card module, weight transmitter, DC-DC converter. All of these are connected to an Arduino board, which I'm controlling everything with. Requirement: Come up with a python code that will do the same task with the same tools, only replacing the Arduino board with a Raspberry Pi. Which will require translating the code which is C++ to Python. Note: The code in C++ is ready and works...
