    ...a video which I have linked to below. The application should be interactive and run from the command-line. Source code is preferred so I can compile for both Windows and Linux using gcc (mingw). The algorithm is iterated consensus (see attached example, and also this on youtube : ). Essentially the process is to systematically compare each string (product term) in a list of such strings and generate new strings using the consensus theorem from boolean algebra. New strings are added to the list and old strings are removed, when possible, using the absorption theorem. When this process is complete there will be a list of all the prime implicants of the input boolean expression (the list of product terms). Complemented variables are usual

In-depth experience with sensor data collection and actuator control is essential, with a particular focus on temperature sensing capabilities. Familiarity with designing communication protocols between devices is also highly desirable, in order to ensure seamless performance. Ideal applicants should have previous projects showcasing their ability to create Arduino devices that can effectively perform these functionalities. I Need a quote for STEP 1 only at this moment.

    Using an STM32F1 Microcontroller and a NFC reader like PN532 (or any other), write C code to a. write a string value to an NFC tag, hereafter referred to as 'data' b. read multiple tags (one by one) and add their data (string value) to an array c. should be able to read minimum 4-5 tags one by one and add their data to the array d. send this array over UART to an ESP8266 (ESP code is not required) e. Use STM32F0 / STM32G0 The tags are placed within reading distance of the reader and the reader must read all tags and log their data to an array. No hardware or circuit design is required, only the STM code is required, along with the description of the hardware used (modules or chipsets that are used). Only limitation is that the NFC reader must be economic...

    ...for this project includes: - Remote device management: The ability to manage connected devices remotely is crucial for this project. - Data logging: It is important for the system to be capable of accurately logging data from devices. Considering my preferences, the successful developer should have expert knowledge and experience with: - Arduino: Familiarity with Arduino's BLE/LORA is a requirement. You should have prior experience coding in Arduino / C++. - Flutter: I've chosen Flutter as the platform for the software development. Correspondingly, knowledge of Flutter is crucial for this role as user will set up the Gateway through Mobile Phone - AWS: The software will use Amazon Web Services for the remote management of data. As such, experience with AWS ...

    I am seeking an expert in Arduino programming and hardware with keen troubleshooting skills to correct an issue encountered in our Laundromat service. - Issue: Our coin-based and bill acceptor's firmware does not register incoming payments when coins are put in to fast (this means bill acceptor is not working at all, since it puts in fast). This bug prevents the immediate update of customers' account balance, which is an expected function when coins or bills are inserted. - Task1: change the current read on port 24, 26, 28, 30 and 32 to open collector, so it registrer a pulse no matter the length. -Task2: The system works with a lcd touch screen, and when a machine is selected, the button for the specific machine will disapere for x amount of seconds, but another freel...
