Summary of Control Relay Card with USB port Atmel using Atmega8 microcontroller
This article discusses a USB relay card project using an Atmega8 microcontroller to control six relays via a computer. It highlights the need for regulated 9-12V AC power and explains how this setup prevents port issues when the computer is off. The text also lists various unrelated embedded projects like CPLD and ARM boards but focuses on the USB relay implementation details.
Parts used in the USB Relay Card:
- Microchip PIC Series (mentioned as context)
- 6 pcs Relays
- Control PCB
- Atmega8 Microcontroller
- USB Port
- USB Drive
- 9-12 Volts AC Regulated Power Supply
- SPI Connection
- RS232 Connection
Once upon a time, though a circuit of this type of calling Searches Banim made with Microchip PIC Series devreydi 6 pcs rörele control pcb computer program code can be done via usb port usb drive and 9-12 volts AC regulated power supply section of the circuit’s schema files on the SPI and RS232 connections have.
In fact, for the computer to control the relay with simple circuits, there are cheaper, but ( the computer and the Device Control ). Although these circuits relays computer is turned off momentarily to his questioning of the port leaves the microcontroller used in the system prevent this problem can only be undertaken.
