![]() ![]() ![]() There's a couple of good online tutorials about these with animations. Common shift registers are 74HC164 and 74HC595. As data is clocked in, it shifts all the other bits over one position with the end one falling off. Serial to Parallel Shift Registers are ICs that allow 'serial' data to be clocked in on 1 pin and stack up in a register which is output on 8 parallel pins (in the case of a 8-bit shift register). This instructable goes over a quick intro to the 74HC595 8-Bit Serail to Parallel Shift Register with Latch and how to interface it to an AVR ATtiny13 to flash some LEDs.ġ - Power Source - 7805 or some other 5v sourceġ - ATtiny13 and a way to program it ( I'm using the AVRISP mkII with AVRStudio 4.17 w/ WinAVR) If you have been playing with microcontrollers and electronics then you have likely seen LED dot matrix displays and other projects that use shift registers like 7-segment displays and more. ![]()
