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.

See the related link below. It is build by using 8051 microcontroller, you can also get the source code from there.
Intel
The only control on a circuit breaker is its on/off/reset lever or button.
The purpose of the battery in a circuit is to wive energy to the circuit

You reset a circuit breaker by pushing the reset button.
With something conductive - like wires or a circuit board.
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.
A circuit breaker is an overcurrent device that can be reset after it has opened.
Most automotive circuit breakers reset themselves after they cool off. Some bigger trucks use circuit breakers that are reset manually. They have a button you push in to reset the breaker after it has cooled off.
there are a lot of sites that provide guidance or complete projects based on 8051 microcontroller. here is one that i found best for 8051 projects http://www.engineersgarage.com/microcontroller/8051projects http://www.siliconray.com/stc-8051-standard-kit.html its one that provide clear illustration of the project with the help of circuit, C code and working video.

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