Arduino Jobs

I have a PCB board with esp32 and mfrc522 and sim800c. There is some coding using Arduino to do some tasks and the rest of code is not yet coded to functional the mfrc522 and sim800c. I'm looking for a freelancer who have a good knowledge about coding the rfid mfrc522 and sim800c using freeartos to communicate with a server by sending the rfid number to a server via the sim800c and get back the result to complete the rest of the code which is ready.

I need realize one software for arduino o raspberry that recognize information during use the toothbrush. All information should be send in one server where I can see it.

I want to create an electronic trigger that is activated by an external source signal. The signal is Manchester code delivered trough a 3.5mm audio jack. (LTC, the end of each frame is identified by a sequence of 12 consecutive highs) The trigger only has to read the signal, display it on a small screen, and allow for a user selectable delay to close a circuit. The trigger will actuate a raspberry pi. I am looking for someone to design and build me 2 or 3 physical triggers. The objective is to create an electronic trigger that is actuated via LTC timecode input. Input Signal: LTC Timecode via 3.5mm audio Jack (the sound is mono, need to check the channel) LTC is a manchester encoded signal, wikipedia has information about it. Each frame end is terminated with 12 highs. I need a ...

Hi I a looking for a Cost-effective Development Team who has experience in the development of ESP32 S3 chip with IDF only. We do not need Development in Audrino.

I need someone experience in Arduino programming. The job is to create the firmware for an Arduino Nano with multiple simple sensors (LEDs, temperature, buttons, EEPROM, RTC, etc...). You need to be able to code object-oriented (a class for each sensor) and know how to have multiple process running (using timers or interrupts, no delays or halting the MCU). It can also help if you know a lot of open-source libraries that can be used/adapted. Detailed specification will be provided to selected candidates.

RFID based Washing machine & Dryer project. This project is regarding controlling a commercial washing machine & dryer using rfid technology. The data of all rfid’s issued will be stored in a database (aws-light sail). When a user swipes the rfid card the terminal, esp32 which is connected to rfid will communicate with webserver & database & will check if the card is present. Depending on the prerequisite conditions, server will send data weather to run the machine or not. If the user has all pre requisites then data base sends communication to run the cycle. Adjacent link can give some idea. When the server sends data to run machines, then two actions are supposed to happen. Action 1: Send a square pulse of certain wave length. (Will be recorded from one of our mach...

I'm looking for an expert on ESP32 and C/C++. The work consists in modifying an existing project written in Arduino IDE for ESP32. Freelancer should know the principle of C++ abstract methods, DMA working with memory, I2S protocol (DAC output). I estimate the result to be a few hundred code lines.

I need someone who develops for arduino uno sketch that can read and write EMV smart cards. So you don't need any intermediate hardware, which directly communicates the Arduino to the IO, RESET, VCC, GND and SCK pins of the chip. The libraries that you have available only serve to understand a little of how communication is done, as they are not functional. I provide research material.

Hi. I need wireless photocell timing solution for equestrian show jumping. This all must be works over internal webpage address (like: ). It should work like this: When the competitor passes the start photocell, the time starts automatically and the start photocell is turned off until the judge has pressed the reset button. Since there are two competitors on the track in the race, one who competes and the other who warms up, the warm up can repeatedly pass under the finish photocell and give the wrong time. Therefore, the judge must be able to delete wrong times on the website and choose the correct time for the end. However, if there is a competition where, in addition to the start and finish, a split time is also necessary, the judge must also be able to choose it. On the website, the ju...

i need a device that when it senses 110 volt power it will keep a running total of hours run , it will be on,off,on,off like the odometer in your car , only runs when power is sensed . it needs to have a resettable alarm that will flash the display or a led at 500 hours, at 550 hours i want an audible alert [beep] that is continuous until reset. i can build it i just need the components required , the schematic and the code for arduino or rasberr pi

I need to use the MPU6050 with nodeMCU (ESP8266) to detect motion and report that to the server, the nodeMCU should be in a deep sleep mode to save power. you have to program the MPU6050 to send an interrupt signal through the INT pin !

Arduino sketch to get time form Internet The board as Ethernet port (Wiznet 5500), AT24CMAC402 EEPROM (to get MAC adress and store variables) and RTC (DS1307) We we need: 1. Initialize the Ethernet interface using the EEPROM stored MAC 2. Use the timezone lib to get the time from NTP server 3. Update the DS1307 and set a flag (inSync=true) 4. Send the time to the serial port Notes: The time must be read from DS1307, so it can output time even if not syncronized. If it cannot get the time form NTP server, the inSync Variable must be set to false (after a few tries of course) The timezone, daylight saving and ntp server must be configurable and stored in EEPROM This variables must be set using the Ethernet port.
