Logic Lab Car Activity
http://www.neuroproductions.be/logic-lab/
Note: This is a puzzle for you to try and solve. Your job is to experiment by adding logic gates, wire splitters, etc. until you succeed on hitting all the criteria of the challenge.
Step 1: Set Up
On the Logic Lab site (link above), set up a car with 4 wheels, a brake pedal, a gas pedal and two turn signals (on the front of the
car). See the picture at the bottom of this document for a good starting layout.
Assume the top pedal is the brake. The bottom is the gas.
Challenge #1: Gas and Brake
Program the car with the following features:
Turning will be indicated by having only 2 of the wheels spinning (like for a tank) and the appropriate light is on or flashing. Turning left will mean the top two wheels will be stopped. Turning right will mean the bottom two
wheels will be stopped. Add two RED BUTTONS to indicate a left and right turn signal (press the
left to turn left). Then program the car with the following features:
Extra challenges:
Here are some fun things to try:
When finished, save this set up and record the web address in your Weebly assignment from last class so that I can view it
later.

Assume the top pedal is the brake. The bottom is the gas.
Challenge #1: Gas and Brake
Program the car with the following features:
- when the gas pedal is pressed (bottom switch), all four wheels start
to spin (unless the brake is also pressed) - when the brake is pressed, all four wheels will be stopped
- when the brake and gas is pressed, the engine should just rev (in other words, all four wheels will be stopped)
- Save this set up and record the web address in a Weebly Webpage so that I can view it later.
Turning will be indicated by having only 2 of the wheels spinning (like for a tank) and the appropriate light is on or flashing. Turning left will mean the top two wheels will be stopped. Turning right will mean the bottom two
wheels will be stopped. Add two RED BUTTONS to indicate a left and right turn signal (press the
left to turn left). Then program the car with the following features:
- when the gas pedal is pressed AND the right turn signal is on, the car will turn right
- when the gas pedal is pressed AND the left turn signal is on, the car will turn left
- if the gas pedal is not pressed, the turn signals will not do anything
- add brake lights
- Save this set up and record the web address in your Logic Gates assignment from last class so that I can view it later.
Extra challenges:
Here are some fun things to try:
- add a bumper that will turn off the engine in the event of a crash
- add a speedometer. Use multiple switches to represent how far down you are pressing the gas pedal and then wire in the counter to show your speed.
- add whatever else you can think of
