I need a circuit to flash 3 LED's such that:
1. LED 1 comes on
2. About 1/2 second later, LED 2 comes on and LED 1 is still on
3. About 1/2 second later, LED 3 comes on and LED 1 and LED 2 are still on
4. About 1/2 second later, all LED's go off and the cycle starts over.
Could someone please point me to such a circuit or give me some idea of the chips (ie.555's?) and stategy I could try. Thanks in advance.
(Excellent board, by the way)
