Question

6. An H-bridge is used to control what two functions of a DC motor? . A microcontroller is executing an interrupt function, or ISR. Another interrupt occurs before the ISR is finished. What happens? a. New interrupt stops original ISR, new ISR executes, and then old ISR finishes b. New ISR is ignored since original ISR hasn't finished c. Original ISR finishes, and new interrupt is addressed afterwards. d. Original ISR stops, new iSR executes, and then program resumes from main loop The number 38900 is sent to the microcontroller from a PC as a string. What is the minimum size of the byte array needed to further convert the string to a number value? If the variable x is a signed int used to represent the number, will the number be represented correctly? 8. a. 5, No b. 5, Yes c. 6, No d. 6, Yes

Explanation / Answer

6)Answer:

DC motor is to use a circuit called an “H-Bridge”. An “H-Bridge” is an arrangement of transistors that allow you to control both the direction and speed of the motor.
