Join Zahraa Khalil for an in-depth discussion in this video MC74HC595A shift register overview, part of Learning Arduino: Interfacing with Hardware.
- [Instructor] Let's take a look at how…to wire up our shift register to Arduino board.…The shift register we're using is MC74HC595A,…which is a serial-in, parallel-out shift register.…The MC shift register consists of eight-bit shift register.…The eight output bits are referred to as QA through QH.…And sometimes we refer to them as Q zero up to Q seven,…depends on the type.…
The serial data is loaded in at pin A Data Serial In,…and the parallel data is available…at pins QA all the way through QH.…If we only have four bits in,…the shift register will shift only four bits out.…And we can control the state of our LEDs…by connecting them to the output pins of the shift register.…Let's get started by wiring up our data…and clock signals to the Arduino board.…
