Okay ladies and gents, here’s a Chasing Light project using a single Shift Register (74HC595) and a TI Launchpad. (I’m currently following a line of research using the Shift Registers, but there is an easier way to do this with just a Launchpad alone.) It can be easily adapted for many uses. Examples include, but not limited to:
- Theatre Signs
- Airport Landing Strip
- Eat At Dave’s Signs
This particular Launchpad project uses an external device called a Shift Register. Simply put, it’s a device that remembers the 1 or 0 you just put into. If you put another 1 or 0 into it, it shifts all the existing saved 1’s and 0’s over one slot and adds your newest value in. It can hold 8 values, hence the term 8-bits.
Here’s what it looks like when its all put together on a breadboard:
