You need a reset circuit in the 8051, as in every logic circuit, in order to ensure that it starts up in a known state.

With something conductive - like wires or a circuit board.


Why there is no driver circuit needed between 8051 microcontroller and an optoisolater?

Are you referring to the original Intel 8051, or one of the many variants? The 8051 has weak internal pullups on the i/o pins, and can source only about 60 ua, but can sink 1.6 ma, still not much when it comes to driving the led in an opto. Some 8051-based dervatives can sink much more current. Atmel's 89C2051 for instance, can sink up to 20 ma per i/o pin. This can directly drive most optos.

What is the definition of a manual reset circuit breaker?

A manual circuit breaker must be reset by hand, as opposed to an automatic circuit breaker, that may be able to reset itself once it cools down.


Is all circuit breakers automatically reset?

No, not all circuit breakers are automatically reset. Some circuit breakers need to be manually reset by flipping the switch back to the "on" position after they have tripped. Automatic reset circuit breakers are typically used in specific applications where it is important for the circuit to be quickly restored without human intervention.


Why won't my GFCI reset when I press the reset button?

There could be a few reasons why your GFCI won't reset when you press the button. It could be due to a faulty GFCI outlet, a tripped circuit breaker, a ground fault in the circuit, or a wiring issue. It's important to troubleshoot the problem carefully and consider seeking professional help if needed.


Why won't the receptacle reset?

Check your circuit breaker. The receptacle may be malfunctioning or you may be overloading the circuit when trying to do the reset.
