Bare bones programming language

Bare bones programming language is a low-level programming language that gives a detailed stepwise description of a program. It has a tight program design and in-depth understanding of the toolchain. It is based on the target environment and is used for safe coding practices. C programming language is a type of bare bones programming language.

Implement a program to do a bitwise complement (NOT) of an integer number entered by the user. You should use the XOR operator to implement the NOT, do not use the NOT operator. Your program should include a proper and useful prompt for input, and print the results in a meaningful manner. use assembly language to code

Based on the Tinkercad circuit accessible from the link below, complete the following activities:https://www.tinkercad.com/things/c1qtxCkOuBW Code is, // C++ code// const byte LED_PIN = 13;const byte METER_PIN = A4; void setup(){ pinMode(LED_PIN, OUTPUT); pinMode(METER_PIN, INPUT); Serial.begin(9600); startTimer();} void loop(){ } void startTimer(){ noInterrupts(); interrupts();} ISR(TIMER1_COMPA_vect){ digitalWrite(LED_PIN, digitalRead(LED_PIN) ^ 1);} 1. Complete the code in a way that LED blinks every 2 seconds.2. Change the startTimer method to accept a double value called timerFrequency, which representsthe frequency of the timer. Change the startTimer function so that it uses the value of this parameterto calculate and set the correct values for the OCRx and TCCRx registers.3. Use the potentiometer sensor connect to pin A4 to enable users to configure the timer frequency. Plsease share the final code only.
