IAMBIC85: "An Ultra Simple Iambic Keyer with Speed Pot"

• At 2019 Jun 29: Now for ALL ATTiny85 (45/25 and for a 13, too !)

No "misteries" here, in only 244 bytes of code !

• Speed: From about 12 wpm to 40 wpm

• Iambic Mode: Iambic "B" ( Yep ! Accu Keyer, you bet... )

• Sidetone: 500 HZ (fixed)

=> At 2019 Jul 18: Changed to 500 HZ pitch (that's more "real World" CW !)

• DC Source: 5V @ .03A ( 30ma )

=> At 2019 Jul 18: Using an external 78L05 (better Speed Pot range)

I loved to put all on base of my Vibroplex Iambic Key

My version was done with an ATTiny 13 (not an ATTiny85 Board as in Schematic)
