5. Draw a well labeled diagram of the PIC microcontroller architecture. [30] 6. Supposed you want use pins of B as inputs and those of Port A as outputs. Explain how you would achieve that (10) 7. For a PIC16F877A Microcontroller to work, a crystal oscillator must be connected between pins 13 and 14. What is the frequency range in which PIC16F877A can operate? [10] 8. Supposed you are programming an alarm system that has 4 zone motion sensors which should Interrupte e low of the programmet.​

What precautions should you take to prevent injuries when dealing with heavy loads?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
