As you can see, they have a description of what’s going on so here it’s. So basically, the final result to light up the LEDs and the way this table works. What that means is you have shifted in your values at this stage, but you need to out actually instruct the device to output what you want. So in this case, they’re setting on input of high into the shift register and as you can see it says, contents of all shift register stages are shifted throughout, which means that basically you’re cascading each element into the next one and shifting a new one into the Shift register also, the very important function is, as you can see, contents of shift registers are transferred to the storage register and parallel output stages. But in a nutshell, what you want to do is look at these different functions and the side of what you want to do, or what what you need the device to do so in this case, we would like to shift a value.
Descriptions within this table which are going to allow us to basically configure the device as we want, and you will see later on how we’re going to program this based on these. Actually, it starts with Q 0, which is on the other side of the IC versus all the other ones, but we got these. Those are the pins that we’re going to use to light up two LEDs. As well as your Arduino without any further delay, let’s take a look at datasheet for Ric, alright, so here’s the data sheet for our 74 hc5 95 shift register and, as you can see, we can find a bunch of valuable information I’m going to post this link Down in the video, if you want to get a more detailed view, you get all the pin outs you get the layout for our device, which pin goes where but, more importantly, we get a description for every pin.
As you can see, I have a lot of them on my breadboard you’re, going to need some current limiting resistors, which we’ve discussed in a previous video going to need a bunch of LEDs, and these are just very basic abilities and you’re going to need a breadboard. Sparkfun amazon, ebay, digi key now you’re going to need some jumper wires. You have a small scrolling example for the eight LEDs on my breadboard, for this particular tutorial you’re going to need an IC, so a shift register the one that I’m using I’m going to link for to the datasheet down below you can buy it almost anywhere. So what does IC does is that it it is able to shift multiple outputs so by using three pins on the Arduino we’re able to control eight LEDs and to just give you an idea of what this IC can.
