This scrolling sign has 96 different characters, and can store messages up to 232 characters long. The messages are stored in memory even after power-down, so it'll be there when you turn it back on. The scroll rate is adjustable to 8 different speeds (including stopped) and you can manually scroll using the left and right buttons.
An intuitive 4-button interface that lets you enter messages quickly. You can also connect it directly to your computer and type in messages with your keyboard. Electronics enthusiasts will find this device a great tool when connected to another microcontroller.
This kit comes with all the parts you need to build a very cool scrolling LED sign, including a professional quality double sided circuit board, a programmed microcontroller (this kit is based on Microchip's PIC16F628A), and high brightness red LED displays (the image below gives no credit to the brilliant bright red). We even include extra parts to let you adjust the display brightness (and power consumption). A 7-9V 120mA power source is required. The kit includes a plug that can be soldered to any power wires (say, from a battery or old wall adapter). We also sell a power supply separately that already has the correct plug adapter.
