BLOGICS!Using a Logic Circuit Simulator
Pontifical Catholic University of Rio de Janeiro – PUC-Rio Introduction to Engineering – 2011.2 – ENG 1000 Coord: Prof Hugo Fuks – Class: 33ALecture: Blogics! – Prof. Denise Filippo – 22.08.2011
Blogics!
1. Run Blogics!2. Check the Environment, Sensors and Actuators tabs.3. What is there?

Blogics!
1. Check the Logic and Wires tabs2. What is there?3. What do you think that Blogics! does?
Environment, sensors and actuators
When it is bright, the LED is turned on.When it is dark, the LED is turned off.
Environment, sensors and actuators
When it is bright, the LED is turned on.When it is dark, the LED is turned off.
Environment, sensors and actuators
When it is bright, the LED is turned on.When it is dark, the LED is turned off.
What if we wanted to simulate the behaviour of a firefly?
Logic gate: NOT
When it is bright, the LED is turned offWhen it is dark, the LED is turned on.
Logic gate: NOT with hardware
When it is bright, the LED is turned offWhen it is dark, the LED is turned on.
Logic gate NOT with programming
When it is bright, the LED is turned offWhen it is dark, the LED is turned on.
Lilypad Arduino
Logic gate NOT with programming
When it is bright, the LED is turned offWhen it is dark, the LED is turned on.
if (sensorValue < 40) { digitalWrite(ledPin, HIGH);} else { digitalWrite(ledPin, LOW);}
And the firefly?
What if the light on turned on when it was dark, hot, dry, or bright, cold and over 100m of altitude, when no one was around, or in any condition when its speed was low?
It is good practice to simulate the circuit before building it with actual components!
EXCERCISES
1. Build the following circuit and see what happens
2. Plays the buzzer when it is dry.3. Turns on a fan when it is dark and hot.4. Create your own!
ANSWERS
2 Plays the buzzer when it is dry.
ANSWERS
3 Turns on a fan when it is dark and hot.
ANSWERS
4 Create your own!
OTHERS
The fan is turned on when it is dark, hot, humid and there is someone in the room.
