Arduino code for embedded led clock with sensor, 90% functional but not fully terminated Please read attached docs and estimate/quote. Your questions are welcome.

Hello, I have a task to send a bluetooth message to an arduino in a graph on the serial monitor. As I do not have a arduino, i have been given permission to use an app on an android phone to display the output. The data that needs to be sent is a maze which i have already done in python using OpenCV, I just have to be able to send it from the computer via bluetooth to the android app for output....

Necesito un diseño (diseño propio, o circuito ya a la venta) de un modulo bluetooth, a ser posible que no se a necesario un arduino o placas adicionales, simplemente bluetooth y bateria, que "busque" cada 30 segundos, un beacon (tambien proporcionado por ti) y si no lo detecta, poner un pin en ALTO , imprescindible ultrabajo consumo de ambos dispositivos

Overview: I'm currently using an esp07-slave triggered by events that sends a message to the esp12-master. The esp12 then directs the ardunio to turn-off a solenoid & sends push notification to the app. The arduino also supports an HC-05 module linked to the android app. The simple app can open or close the solenoid. Arduino also uses a manual push button momentary switch to open or clos...

Hello, I would like make simple Web server on ESP32 to control few buttons. I want connect to web server from internet(External ip) and control it. You can use any free libraries in internet and embeded in project. I dont like solution like dyndns, dynu,.... or my router port forwarding. I have dynamic IP for my internet. For this project we can use my own linux server(cloud) for tunneling interne...

I want to activate the sensor with a distance of 50cm. to play a sound from the mp3 player. I was working with the same mp3 player with different sensor, the sensor broke today. now this is all I have. my deadline in 10 hours. can anybody help please. Thanks

Multiple Bluetooth Beacons will be moving in an indoor open-space. Through Bluetooth-Wifi gateways (iOT-gateway) the accurate location needs to be identified on the virtual map of location. It will be sent to the dedicated server.

I am looking to have a small mini microphone built with bluetooth capabilities powered by a lithium ion battery. I would like one built along with a full build order.

I am looking for someone to design a simple high side PWM circuit. This will be running at 12-15vdc and could theoretically have a load of 15A max. It can't be low side because the negative terminal of my PWM controlled device is grounded to the frame. I prefer Kicad, or Fritzing as those two are easiest for me to customize my board layout in. If you can make the circuit entirely using digike...

arduino code for embedded led clock with sensor, 90% functional but not fully terminated

I need sensing components lodged to file, using Python code for Raspberry Pi 3. Displayed on a GUI system assessable over the internet. This might need a components Engineer Skill set as an advantage. An idea of a simple system is attached, please offer your advice.

Seeking a freelancer to design our project. We wish to take readily available scales the have BLE 4.0 and leverage the new BLE 5.0 protocol to implement the mesh and beacon abilities within the product development. The scales we have access too, already have the ability to send weight we want to add temperature and battery/charger voltage to be sent to an app we want to develop. The micro-cont...

I need a sample code in Arduino for STM32F103 uC to bring the uC to sleep mode and wake it up by external interrupt and internal RTC alarm. the power consumption of uC should not be more than 10uA in sleep condition. when uC wakes up it continues from the point it stopped. There is no ADC on this project. we need to access 2 serial ports, I2C bus and few input/ output when device wakes up. Maxim...

Require to programming this microcontroller from scratch. All hardware required will be informed by you

This is about a motorcycle project. I want to control 5v signals (max 4 of them). I need to calculate the HIGH ones. When the calculation meets a specific limit number and a switch is pressed I want to interrupt the signal. This is the basic idea, it will be a bit more complex in the end but I don't want to make the project public. I also want to set the limit through a smartphone applicatio...

A simple clockdivider code but if you need more details message me. I am a student so I would give 10 dollars for this. Need it in 2 days

I am using arduino mega 2560. I have a master arduino and a slave (display). They are communicating over SPI protocol where display expects the master to send data at 50 KHz i.e. the SCK pin from master to slave should operate at 50 KHz instead of buit in 16 MHz clock. Is there a method to reduce the clock frequency ? Altrernative method (no preferred) would be to generate a 50 KHz signal using ti...

Please only quote, if you are familiar with Apple's MFi program. We need help to create an MFi compliant esp32 system to support a serial bluetooth connection to iPhone via iPhone Classic. We have a fully function ESP32 device which supports serial bluetooth for Android. But to get the hardware right, we must add Apple MFi compliant Bluetooth Classic support for a serial connection to iOS ...

I am looking for someone that can do a raspberry pi project for a tool control project I am proposing. What I am looking for is when a hall effect sensor is tripped it will light up a led and then display the tool name on a screen via HDMI. Then when the sensor is un tripped the led will turn off and the tool name will be removed from the screen. I will need to control a minimum 256 sensors. I...

I need someone to help me with a project that I am working on which involves an arduino that is connected to 6 push buttons as inputs and 6 motors as outputs. The theory is pretty simple, when one presses a particular button it should trigger a certain - or several - motors to be on for a short amount of time, and then turn off. I can give more details to whomever takes this up.

Arduino and simulink should communicate in real time without any time delay. Send and receive data from arduino to simulink and back, after processing it without any time delay. As an example "[Logga in för att visa URL]" but it contains delay when plotted as shown in figure.

What I want is a simulation(proteus, matlab). It can be divided in to 3 part or more. 1: Solar energy is converted into electrical energy to supply large battery energy storage devices then supplying 230V AC 2: Substation's electrical energy converted to 230V AC 3: compile code by using a microcomputer like Arduino Programming software(MPPT method=Perturb or observe or Incremental conductance...

The car runs on 6.4V battery. It is all wheel drive car - all four wheels turn when throttle is pushed to drive forward or backward. There are two motors that allow to achieve this, one is located at the front of the car and the other one is at the back of the car. These two motors work fine and there is no issue with the the forward and backward movement. The problem is that the steering wheel o...

I need an IoT app to be developed. I have pH, humidity, TDS sensors and an arduino kit. I would like to build an IoT app to monitor quality of water at 4 intervals every day. Once the values are in these values need to be matched with drinking water standard to determine if it is safe to drink the water or not. I would like to collect this data from multiple places and aggregate it on to a map.

Hola, necesito a alguien con experiencia en desarrollo de este modulo de SIMcom 7000 o 7100 para comunicación 4G y GPS

I'm working on a prototype for a project and I need to source a circular LCD/OLED (or similar) countdown display timer - see the attached rough sketch. The timer must only countdown days automatically, not hours, minutes or seconds, and be operated by a battery that you would get in a digital wristwatch or car key fob. It needs to be simple and basic in its functionality. If I want to set t...
