We can say that an interrupt is an automatic transfer of software execution in response to a hardware event that is asynchronous with the current software execution. This ensures that the interrupt function completes well before the next one occurs. Software interrupt can be invoked with the help of int instruction.
Consider a fast moving car, if it suddenly gets hit by an another car in opposite direction, the first thing happens is the accelerometer sensor present in the car senses a sudden deacceleration and triggers an external interrupt to the microcontroller present in the car. The interrupt that is caused by any internal system of the computer system is known as software.

Now its time to learn how to use interrupts in arduino uno. Software interrupts in arduino or nodemcu arduino stack. As its name says, interrupts, interrupt the normal program flow to perform an action run another code block, function, etc. Programming using interrupts is very different from the usual toptobottom sequence in an arduino program and thus can be confusing for some. So the only thing that your interrupt could possibly ever interrupt is the next line after the readstring command which is the section that you want to put in the interrupt.
