Thank you for purchasing the Getting Started with Breadboarding Kit at Maker Faire! We’re glad you picked one up, and hope you have a great time playing and learning with it. Below are five sample projects you can complete with the components included in the kit.

If you’ve never used a schematic to recreate a circuit before, this guide will be helpful. And here’s a fantastic tutorial on getting up and running with a prototyping breadboard, courtesy of Jody Culkin:

1. LED Pulser Circuit using Op-Amp: build a simple LED blinking circuit with an Op-Amp. Change the resistor values to achieve different blinking frequencies.

1 LM358 Op-Amp
2 4.7kΩ Resistors
1 10kΩ Resistor
1 22kΩ Resistor
1 47Ω Resistor
1 MΩ Resistor
1 1uF Electrolytic Capacitor
1 LED
1 Bipolar NPN transistor 2N4401
1 9V battery with snap connector

LED Pulser

2. Simple Light Theremin: build a simple theremin with a photoresistor and 555 Timer. Move your hand over the resistor to make some cool sounds! Try using a flashlight and your hand to make some cool effects.

1 NE555 Bipolar Timer
5 Photoresistors
1 100uF caps
2 1uF caps
1 1kΩ Resistor
1 8Ω Speaker
1 9V battery with snap connector

Light Theremin

3. Toy Organ: use this simple toy organ to play five different tones. Use the potentiometer to adjust the tune of the organ on the fly.

1 NE555 Bipolar Timer
1 4.7kΩ Resistor
4 1kΩ Resistor
2 10kΩ Potentiometer (3362 trimpot) w/ knob
1 10uF Electrolytic Capacitor
1 0.1uF ceramic capacitor
1 8Ω loudspeaker with leads
5 SPST mini pushbutton
1 9V battery with snap connector

Toy Organ

4. Electronic Cricket Circuit: Make a simple cricket circuit that chirps at a frequency depending on the amount of light hitting the photoresistor. Instead of using a speaker as feedback, trying switching in a few LEDs instead!

1 NE555 Bipolar Timer
1 Photoresistor
1 10Ω Resistor
1 2.2kΩ Resistor
1 100uF Electrolytic Capacitor
1 8Ω speaker with leads
1 9V battery with snap connector

Electronic Cricket

5. Dark Detecting LED: build a simple night light with this circuit. The LED gets brighter when it detects less light. Adjust the resistor values to change the sensitivity of the device.

1 Bipolar NPN Transistor 2N3906
1 Photo Resistor
1 Super Bright LED (green)
1 270Ω Resistor
1 100kΩ Resistor
1 9V Battery with snap connector

Dark Detector
