starting circuit for programmable sequence, for flashing LED? Answered
I am interested in suggestions for starting points to build a programable flashing LED. The intervals of dark/light should be configurable, kind of like morse code. But not subject to what I recall as requirements for Morse- dashes are 2x as long as dots, or something- duration will vary for both. Maximum total length of sequence is 10 seconds.
There are a lot of flashing LED circuit Instructables, some very old and referencing 7 yr old chips- unsure if I can get those chips.
In an ideal world, when I am done, I could have multiple EEPROMs that I could switch out to configure the flash sequence I wish. One sequence per EEPROM. Or another means to accomplish this.
My background: I can solder a little, I can program and shell script a little, I have not much idea about electronics at all.
Thank you for pointers to a jumping-off spot for me!
