This 2000’s circuit causes LEDs to flash sequentially from programming on an 80C51 microcontroller. The circuit has an additional TTL and must be powered by a 5 V power source.
The resistors R determine the frequencies of the oscillator together with C. The circuit is from a...
This circuit can be used as shield or to drive powerful loads from low current switches such as...
Two of the four gates of a 4011 is used in this biestable touch circuit. Do not use a power source...
