Adding a cheap LCD to your PC is a popular diy project for many beginners in electronics. The parallel port however, is dead. It’s obsolete. It’s big…ugly and just awful. The solution? Add a USB interface to your existing LCDs. The circuit interfaces to a standard HD44780 compatible LCD and emulates the CrystalFontz serial protocol over a virtual COM port created by the FTDI chip. This enables you to use already existing software to speak to the LCD, for example the popular program LCD Smartie. The circuit uses an AVR microcontroller, the tiny2313, and a USB chip from FTDI.[more]

Here is the new 6 channel relay USB card to switch from different devices, lighting or motors by a computer program via the USB interface. Es kรถnnen bestimmte Schaltfolgen via Computer programmiert werden. It can be certain Schaltfolgen via computer can be programmed. Bei dieser Karte wurde auf SMD Technik verzichtet und ist somit auch das optimale Bastelprojekt fรผr Anfรคnger und Einsteiger. This map was waived on SMD technology, and is therefore also the best Bastelprojekt for beginners and novices. Wer wollte nicht schon immer mit seinen Computer was Steruern.
