How to control a led with a switch?
Algorithm to control the led using the switch (SPST) 1 The microcontroller pin connected to the led makes the output. 2 The microcontroller pin connected to the switch makes the input. 3 Continuous monitor the status of the switch, if the switch is pressed then led pin status high either make it low.

How are microcontrollers and LEDs interfacing with each other?
The microcontroller pin connected to the led makes the output. The microcontroller pin connected to the switch makes the input. Continuous monitor the status of the switch, if the switch is pressed then led pin status high either make it low. Interfacing of led and switch with 8051 microcontrollers
How to connect a push button switch to a LED light?
Again check the status of pins connected to push button switch if still it in the changes state then make the led pins high to blink the led light. Here I have tried to discuss a lot of points regarding the switch and led but I would like to know your opinion on the connection of led and switch.
How is a switch used in a microcontroller?
The switch is an input device. When interfaced with microcontroller, it can be used to control other peripherals connected to the microcontroller. It basically “makes” the electrical circuit by establishing the flow of current. Or “breaks” it by interrupting the flow of current.
How is a SPST switch connected to a led?
The microcontroller pin connected to the switch makes the input. Continuous monitor the status of the switch, if the switch is pressed then led pin status high either make it low. In the below circuit, I have connected an SPST switch with P1.1 and a Led with P2.1.
Why is interfacing of switch and led important?
Interfacing of switch and led using the 8051. Input and output devices are the important components of embedded system, we cannot imagine any embedded device without the input and output device, switch and led are the basic example of input and output device, so it is very important to understand the interfacing of the switch and led.
