HDD Clock Circuit Atmel ATmega128 DS1307 TDA5410 Motor Driver

Earlier, I mentioned a few applications to evaluate broken hard disks under the title of “Assess a Bad HDD”, I used it with sandpaper, there were clock projects on the web, now there are hard disk clocks in the shared project, but it is very professional and all resources are shared.

Other active integrated circuits based on the atmel atmega 128 are ds1307 rtc clock and tda5410 dc motor driver. In addition, it can be controlled with a remote control. There is an RS232 communication section, and a large part of the hard disk is equipped with smd rgb leds and there are various effects.

It is based on ATMEGA128 microcontroller. The program does not even occupy 10% of the flash memory. It used the DS1307 chip as a real-time clock. The engine is controlled by the TDA5140A running in a standard configuration from the datasheet.

The device is equipped with an RS232 interface through which you can install new software using the bootloader after putting everything together. ATMEGA128 remote Control is done using a small universal remote control operating in the RC5 standard. Relatively bright tri-color SMD LEDs are used as backlight.

SMD materials are used in most of the circuit. For Atmel users, there are all source files that will be a good example for many subjects (rgb, pwm, remote control, motor driver, etc.) in software and design.

It’s a very costly and tedious application to evaluate a corrupted hard drive, but the result is superb.
