    Hi i need some help with an idea i have. I would like to develop a product for Tuya SDK. I need someone who program the system for testing(On Tuya and on the system itself). What i have right now: NODE MCU (ESP8266) Arduino Nano 3 x 3V Dosing Pumps 1 x ULN2003 Stepper Motor Driver On Tuya it needs to be shown: - 3 Pumps - Calibration button option of each Pump (on click 50ml should be pumped in case more or less is pumped than a correction value needs to be sent to device) - Button to pump a defined amount of liquid - A timing option to plan the dosing for each day of the week and the times and how often (for each pump individually) - It should be possible to rename the Pumps. Thanks in advance!

    You must live in the Western Balkans, Eastern Europe, or in Latin America. This is essentially a Python project. I'm looking for 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 like Arduino). You do *not* need to currently possess an ESP32. 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. You need to be able to work five days each week for one hour each day. You may choose the five days that are convenient for you. You may work at any hour of the day (or night) that you prefer.

    ...unsuccessful soldering of leads. It would be great if we could turn off the previous function when switching to a new function. So for example, when in Drive and then switching to the Park position, it will automatically disengage the Drive function. I can do this with relays, or if you can come up with a robust automotive design to do this, we can discuss that function as well. I prefer not to use Arduino for this function in an automotive unit. The successful bidder will ship me back, at my cost, the wired connector so I can just plug that into a brand new device to complete the functions above. I need to test your completed and wired new connector in the new unit to make sure it works successfully before final milestone payment. Any thoughts, comments, or questions please...

    It is necessary to change part of the code that is written in C, for arduino nano. Now that device monitors the 0-5V analog input, it needs to be modified to read pulses (frequency). The device is fully developed, schematics and PCB. The code must be maximally optimized so as not to affect the speed of the device.

    I’ve had some code written recently for an Arduino UNO R3 that has two inputs. A dry contact and a ultrasonic range sensor. The issue I’m having is that if left alone for several hours it seems to freeze and not work until we have rebooted it using a power cycle. Any ideas on how to prevent this malfunctioning? I can’t share the file with everyone here but will obviously share this with those that have shown they have a lot of experience in Arduino UNO R3 programming. It would be beneficial to know if you have a solid idea as to what may be happening instead of a “Let’s try this or let’s try that” hoping that something will solve the issue.
