• What is a sensor?
• What is digital logic
• How are digital processors designed?
Students will be able to answer the following questions:
1. How many possible outputs are there for n-digital inputs?
2. What is a “don’t care” condition?
3. How do the OR, AND & Inverter gates work?
Students should be able to:
• Design and build a circuit that triggers outputs based upon combinations of sensor inputs.
Students will know:
• How to calculate a binary number
• How logic gates function
• That no voltage is not the same as:
a. The low voltage value
c. Negative battery terminal
• How to build a circuit
• How a simulator can assist an electrical engineer
Create a monitoring circuit that with timing that dispenses aspirin for heart attack and stroke survivors at a regular time. There are risk factors associated with aspirin therapy. Generally, aspiring isn’t given to a patient who is experience high blood pressure, bleeding or asthma systems. The monitoring circuit will emulate the detection of the risk factors by checking blood pressure, anemia (blood loss) or serum periostin (asthma). At the specific interval, the monitor will:
- Dispenses if no risk factors exist - Green LED
- Dispenses medicine with warning if one risk factor is present- Yellow LED
- Doesn’t dispense medicine if risk two risk factors are present - Red LED
- Doesn’t dispense medicine if risk all three risk factors are present – Sounds alarm
Create and demonstrate an anti-theft warning circuit that:
- Illuminates green LED if there is no input to light, sound and touch sensors
- Illuminates yellow LED if one of the light, sound and touch sensors receives input
- Illuminates red LED if two of the light, sound and touch sensors receive input
- Sound an alarm (using a circuit created by students) if all three sensors (the light, sound and touch) receive input
