i need help with number 4 and 5 please and thank you.

1. List five possible embedded systems in each of the following: a child's bedroom/playroom, the kitchen, and the office, 2. Consider a domestic washing machine. Sketch its control system as a block diagram in a similar manner to Fig. 1.5, identifying as best you can its sensors and actuators. Assume it is controlled by a single microcontroller. (Note: the main point of this exercise is to visualise a product in terms of an embedded system, not to achieve technical accuracy.) 3. Repeat exercise 2 for a desktop printer. 4. An application is to use either the 12F508 or the 12F509. It must retain a scratchpad area of memory of 12 bytes, and also be able to store in RAM three variables of 4 bytes each, and 36 single bits of data. How many bytes does this amount to, and can the smaller device be used? 5. Access the 12F508/9 data sheet from the Microchip web site (Ref. 1.2), and by reading the first few pages answer the following questions for the 12F508. (a) What is the clock frequency range? (b) What is the frequency of the internal oscillator? (c) What is the operating voltage range? (d) What is the technology of the program memory? 1.
