Material Highlights

Setting Up for the Week

In the first class, students prepared for the month-long course. Students learned each component of the kit and how to set current limits on power supplies to keep from frying the parts!

Basic Circuts

The first few days of class were filled with simple circuits to help students get acquainted with using a breadboard. This meant focusing on architecture with clean wires lying close to the board.

Resistance and Frying wire

To learn the concept of resistance, students used their power sources to burn wire turning it solid, liquid, and finally to gas. They applied the concepts learned to real life examples like a grocery store.

Gates

Transistors were introduced allowing students to make complex gates to manipulate LED lightbulbs with the push of a button. These gates include the "OR", "NOR", "AND", "NAND", and more.

Binary Calculator

Using two half adders and an "OR" gate, students worked together to build a binary calculator. Each student focused on their own breadboard to connect to the whole.

Photocell

Students learned how to use photo cells to manipulate circuits with light, allowing them to make nightlights!

Capacitor

Students used the power of capacitors to charge and discharge the components with aluminum which caused sparks.

The Astable Multivibrator (Clock)

Students used their knowledge of capacitors to create the astable multivibrator. This circuit uses two capacitors to create blinking lights. The size of the capacitor dictates the amount of time until the light changes.

Integrated Circuit Chips

After learning and building the inner workings of logic gates, Students switched to integrated circuit chips to expand the possibilities of their circuits.

Arithmetic Logic Unit

Students use concepts learned from the binary calculator to create a even more powerful circuit: the Arithmetic Logic Unit (ALU). This circuit can add and subtract with not just positive numbers, but also negative.

The 555 Timer Chip

The 555 timer and the Shift Register (74164) chips were instrumental to the last few assignments completed in the class. These circuits included the binary counter and mouse trap game.

The Shift Register 74164

Students use the 555 Timer chip and the Shift Register Chip to create their first puzzle circuit, the mouse trap game. In this game, a blinking light races around the circle, and the goal is to use the stop button to land on the green LED.

Soldering

In the last week, students learned how to solder. Students picked from kits which included an AM Radio, sound detector, voice changer, metal detector, love tester, dice, and stop light. After making, students were able to take their creations home!

Puzzling Week

To complete the course, a whole week was dedicated to solving puzzles. From passcodes to radios, students were able to explore!
