    2,000 ttgo esp32 oled งานที่พบ

    Need someone to add 2 pretty simple feature to our existing POS esp32 firmware. 1. Turn wifi strengt up to maximum strength. 2. Make the device restart when WIFI connection is lost for more than 120 seconds. Thats it, should be a relatively simple task for someone with esp32/ Arduino experience. Dont bid less to get the project, WHAT YOU BID IS WHAT YOU GET NO MORE!

    Python developer - No experience necessary
    หมดเขตแล้ว left

    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 need to live in the Western Balkans, Eastern Europe, or Latin America. 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.

Please let me know if you have any questions regarding it, as could be a bit difficult to understand. Here is a video that shows an *old* version of the game in action, which is incomplete and a prototype, but showcases the basic features of it: This must be done perfectly! The game should not require Internet access to work, this should be OPTIONAL. So, if the establishment has WiFi then we connect the server but otherwise we turn it off. Please let me know
