Without using a Timer function, write a program to read the distance from the HC-SR04 ultrasonic sensor and display the distance on the C12832 lcd.

*please refer the HC-SR04 datasheet for the operation of the ultrasonic sensor, and mbed website for C12832 library and Timer function

At time t = -250/6 μs a sinusoidal voltage is zero and is increasing. The next zero voltage takes place at t = 1250/6 μs and t = 0, it has a value equal to 75 V. This voltage is applied to an inductor, whose inductance is equal 0,0041 H

1. Define and explain these types of errors that may occur in sensors: Offset, scale, nonlinearity, hysteresis. Give an example.

A T flip-flop is a 1-bit synchronous storage component alternative to the D flip-flop, with a slightly different interface. The T flip-flop has one input t to synchronously control the state of the flip-flop, as follows:

When t is 0, the flip-flop does not change its state value.

When t is 1, the flip-flop inverts its current state value (0 becomes 1, and 1 becomes 0).

Write a Verilog module for the T flip-flop using a behavioral model. The flip-flop should be triggered by the rising edge of the clock input. It should also have an asynchronous active-low reset input to reset the flip-flop state to zero
