S3 INNOVATION ELECTRONICS

LESSON TITLE: ELECTRONICS Learning Intention: To understand when to use different types of logic gates Activity: Building own circuits using logic gates Success Criteria: All – Understand when to use NOT, AND and OR gates Most – Be able to use more than one gate at a time Some – Build a logic table when using more than one logic gate

OR gate An OR gate has two inputs and one output. An OR gate requires either one or both inputs to be ON to be ON. Input 1Input 2Output

Example Collect a circuit board, connect wires as shown. What could this circuit be used for?

Inputs We have only used the switches so far. What happens when you cover the light sensor? What happens when you cover the temperature sensor?

Challenges Your teacher will hand out a list of jobs for you to complete using the logic boards. Work through as many as possible. Make sure to make a block diagram as well as truth table for each job.
