1.6-1.7 How electronic systems and programmable components provide functionality GapFill

A program is built up of functions, including  yes or no answerswiresbatteriesinputs and outputs.   These functions are typically a set of questions, with  yes or nocalculatedinput and outputdirect answers.   A computer will use these questions and answers to make  choicesinputsdecisionsresults, which will result in a calculated output. The next instruction or question will only happen once the program has detected an input.   This output could be another device, such as a  resistormotorcircuit boardwire, which will only respond once the computer has told it to.   A  diagramflow chartchart gridbar grid is a method used to communicate a system like this, with the use of different symbols.   Some sensors are not digital, they are  linearrotarynumericalanalogue; for example, a  a batteryan LEDan LDRa switch. The output of this component will respond to temperature changes. A computer can be programmed to respond to these changes.   A  time delaygapswitchcount is a type of function that tells the electronic system to wait. The program will pause for 10 seconds and then move on to the next question or instruction.   A countA sumA time delayA feedback loop is a type of function that records how many times it receives an input.   A  feedback reversefeedback ringfeedback circle feedback loop is a type of function that sends the program back a previous point in the flow chart, to repeat a set of questions or instructions.   The functions will keep repeating until the  signal goesprogram stopsoutput changesanswer changes.
