    I tried all the variants and it still does not work.
    The controller is programmed, it has quartz oscillation, IR receiver is ok, ok links.
    Is there a possibility that the firmware is not loaded to the correct address?


    If you're sure that mcu is good, then perform troubleshooting with driver, like a high state on pin 8: MOTON should make hdd motor spinning,
    as well just after power on, mcu should have high state on pin 51.
    It's hard to guess, check connections, or vias, cold/dry solder joints, if you have spare mcu or driver, try to replace.
    I'm using avrdude for flashing mcu, no need to change address, just a simple command like:
    Code: Dos

    Hello, did someone like this clock on the arduino plate? Maybe someone knows a site where it is nicely described?

Topic summary

The discussion revolves around the creation of a clock using a hard drive (HDDClock), where participants share their experiences, challenges, and solutions related to the project. The clock operates by utilizing a rotating plate with RGB LEDs that illuminate through a cut-out slot, creating a visual display. Key topics include the design and assembly of the clock, the selection of components such as the TDA5140A motor driver, programming the ATmega microcontroller, and troubleshooting issues like motor control and sensor calibration. Participants also discuss the importance of balancing the disk, the impact of power supply on performance, and the use of various sensors for detecting the slot in the rotating plate. The conversation highlights the collaborative nature of DIY electronics projects, with users providing insights and assistance to one another.
