    Looking for a programmer that can create a program that will set the temperature of a device. The inputs are simple which is just up and down. I would like to have the ability to set the number of clicks. Initial idea on how the program works. 1) connect the hardware/device. 2) program will detect device. 3) program will input commands, up or down by the set number of clicks. 4) disconnect device. 5) Repeat steps 1-4 and the program will automatically start. Currently using a simple board. Pics attached.

    You must live in the Western Balkans, Eastern Europe, Latin America, or the Caucasus. I am seeking either a high school student or a university student to help me build an Internet of things (IoT) device using MicroPython on the ESP32. (ESP32 is a microcontroller just as Arduino is a microcontroller). Why don't you need any experience? I would rather work with someone who is inexperienced yet very intelligent, rather than someone who is experienced yet not very intelligent. I will ask you a question that you must answer correctly, to prove to me that you are very intelligent. You must be able to work for five days each week for one hour per day. You may choose the five days which are convenient for you. You may work at any hour of the day (or night) that you would like.

    HART pressure transmitters for configuration via a distributed control system (DCS) or HART communicator. HART pressure transmitters are compatible with the Highway Addressable Remote Transducer (HART) communication protocol which is the most popular standard used with smart field devices by the process control industry. HART functionality enables the transfer of pressure transmitter data via an AC digital signal which uses the 4-20mA analogue output signal as a carrier, thus eliminating the need for extra wires and connectors.
