(1) Write an iOS and Android apps that discover and connect with a device via BLE radio (2) The apps needs to send and receive data to and from the device via UART service (3) The apps needs to present the data in graphic form or histogram (4) The apps needs to push data with GPS location information to a cloud server. (5) The device hardware is ready with a set of AT commands completed and currently works with nRF Connect apps (Android version) from Nordic.
I want to read clean audio signal from a i2s microphone. I should be able to set the select or reject desired frequeency range. The output should be routed to the audio jack. Also it should be routed via bluetooth via A2DP profile. The hardware platform ESP-A2S , ESP-ADF, and so on.
I'm looking for a programmer capable to program the CH559 () chip. In particularly I need to modify an existing open source project () and add a configuration interface on the serial port. This configuration interface is used to remap USB serial HID data to a specific serial protocol. The mapping should be done either using a GUI or an API.
I am looking for an AVR/ESP programmer who will help on the code to generate an 8 pulses signal at various frequencies and various duty cycles using ESP 32 and ATMEGA328P based arduino NANO. The frequency varies from 200Khz to 1Mhz. (There is a table for the various signal pulses on the PDF files). The 8 pulses are to drive a PNP transistor! An image of a pulse we are looking to achieve. The signal in Yellow is the result we are looking for. I have other tasks as well!! Can you do it?
1. This is a project based on a circuit board. I will provide the schematic diagram later. In the picture you see a BLE module, but I will try to add one more. 2. The connector on the upper left has 4 input, 12v, gnd, CAN+ and CAN- 3. The 4 connectors on the bottom is pretty much the same, it control 4 identical components. Each connector has 6 wires: Gnd, two output for dc motor, ws2812 data, 5v, and a switch trigger. 4. Whenever a switch is pulled to ground, it will trigger the motor to pull for 1 second. 5. Whenever a motor is pulled, the ws2812 will start to light up. 6. After 20 seconds, the motor should reverse back. And the Ws2812 strip should light off. 7. Whenever a certain CAN signal is received (will be provided), all the 4 motor should pull for a second. All 4 ws282 strip will...

To develop codes in Max For Live, to sync many servos with music /beat tracks in Ableton Live. Sync 50+ tracks with 50+ individual servos. Each track will be designated for certain function in a Dancing robot. Extendable number of tracks/servos. Wifi connection from PC/Ableton Live to many arduinos, which are connected to the servos (around 5-10 servos per arduiono).
I have a Project at hand which requires a BLDC motor to be RPM controlled. Basically, the shaft has to rotate at a constant RPM with varying loads. I’ll give more details to the selected freelancer. So basically, the tasks to be done are: 1. Selection of Motor from online websites based on my requirements. 2. Selection of Motor controller from online websites or design one. 3. Design/coding of a Arduino based PID controller or be combined with the motor controller. 4. An AC to DC circuit design for powering the motor or selecting some readymade stuff. I am not an Electrical Engineer so I might not be able to give much technical details.
Make a Blackberry RIM 950 style phone using SIM800C and Arduino chip. The phone should be able to send SMS and be used without a gsm line like a walkie-talkie. It should have a solar panel on the back and be able to charge the phone. You can check this video

I need an Arduino based program for hidden mesh communication over wifi + Bluetooth for ESP boards where one of the boards will be acting as MQTT Server + (MQTT Client for another MQTT Server) and in case the local MQTT Server (one of the boards) is offline, then the other boards will communicate through the mesh without affecting their communication and functions. All boards can be programmed OTA. The boards that have Nextion screen can update and send the graphic file OTA. Boards can communicate over Modbus (Wifi+serial) for the related points while the board with MQTT Server can report all the MQTT points over Modbus too. Web server with custom password for assigning the required parameters like wifi, MQTT, name, nextion file location for upload, arduino file for upload,..... Adding BA...
Game design using embedded C aurdino programming Task Build a game system that makes use of digital, analogue inputs and outputs as well as sensors. Use Tinkercad to fully implement the prototype of your design. Make use of as many components available to you on Tinkercad as possible, eg. sound output, multiple LCD, switches and input sensors, to implement a fully functional game in Tinkercad. The game should have at least two game play levels. Game with higher level of complexity in game logic, functionality, optimized code and/or hardware complexity will get higher weighting. Note: - It is expected that the game you select will most likely be unique to you compared to that of other students and what is available on the internet. Creative solutions that make use of more sensor opt...
I need to build and code an Arduino. I want to Control 4 relays to switch on devices. There must be a web front to adjust times, the duration that the relays will be open, and an option that set the priority of the devices. So that only 1 relay is open. I would also like to add something to monitor the load on the relays.

It is going to be a smart carpark using arduino lora technology and wifi as well it should have a website plus app on ios and android able to receive push notifications. The app and dashboard should be something similiar to blynk but it can not be blynk.
In this lab, we will investigate pulse-width modulation and interrupts. Our design intent, is to push a button on the MCU which triggers an interrupt. Once triggered, the specified color LED on the development board must fade-in linearly (min to max intensity) during an interval of x seconds, stay at maximum brightness for y seconds, and then fade-out linearly (max brightness to off) with a duration of z seconds. Your personalized values for x, y, z, and color are given in the attached PDF. In this lab, you cannot make use of "delay" or equivalent routines (millis) to implement the intervals but must make use of the timers incorporated into MCU. Furthermore, you must implement LED intensity variations through the use of pulse-width modulation. You should use the ledcXX...
OPERATION: Use pulses from a water meter to record the gallons per minute every 15 minutes for a duration of 240 minutes. IF the gallons per minute ever goes to '0' during the 240 time, THEN operate a motorized valve to close approximately 5 degrees every 20 seconds until water flow is detected by the water meter. Maximum number of "5 degree" steps is until the valve is 75% closed. After flow is detected continue to record gallons per minute every 15 minutes for the initial 240 minute duration. REPORTING: After the 240 minutes has elapsed, a .csv file is to be sent by email (address hardcoded) using 4G cellular modem via a gateway and service provider based in the USA. Include all recorded data points [Date] [Time] [Elapsed Time] [GPM] (16 lines total). Message Subject...
I'm working in Unity game development (very very basic level). I have a scene that needs to enhance to external 3-axis BLE sensor. I have tried to code but it was not possible to create the enhancement. By now the scene runs with an internal 3-axis sensor but I need to change it to BLE. I just need this part of the code, to either work on what I already have, or create a very simple scene that allows me to enhance my external sensor. The external sensor is with an Arduino simple send buffer code.

Quisiera controlar la activación de una placa con 4 relés a través de una pantalla táctil con 4 "botones" virtuales. Un relé siempre estará activo y se desactivará al pulsar otro en la botonera, que no se activará hasta que el otro no esté desactivado, dejando 0,5 seg entre la desactivación del primero y la activación del puede haber 2 relés activos simultáneamente. En el centro de la pantalla habrá un botón que desactivará y reactivará el relé activo. Adjunto una imagen inicial del diseño de pantalla.
