Join Zahraa Khalil for an in-depth discussion in this video Wire up the input and clock signals, part of Learning Arduino: Interfacing with Hardware.
- Okay, so let's give it a start.…Let's start connecting pin number 14 in the shift register,…which is the data serial in,…and you are going to connect it…to the Arduino board pin number eight.…Alright so the way to note the numbers…within the shift register…is by using the indication, the dot over here.…So you start from number one, two, three,…all the way to eight,…and then the other side, nine all the way to 16.…So we're using pin number 14,…over here, and this one goes to pin number 8.…
Now we'll talk about how to control the inputs.…We're using two essential pins.…First is the shift clock, which is pin number 11…in the shift register.…Data is shifted on a low-to-high transition…of the shift register clock input.…And we're going to connect this…to pin 11 in the Arduino board.…
The second clock is the latch clock,…which is pin number 12 in the shift register.…This input latches the shift register data.…The data in the shift register is transferred…to the storage register on a low-to-high transition…of the storage latch input.…
