About this event

A Breadboard is a great tool for quickly testing out a prototype circuit or hooking up a quick experiment. In this workshop, we'll introduce you to hardware hacking with breadboards by turning your phone or mp3 player into a musical device with an LED that beats to the bass of your songs! You must bring a mobile device with music pre-loaded. See the video demonstration here:


*the Pringles can is simply used to reflect light in the video. 

No programming involved and you keep all the equipment from the workshop.
This project includes:
• Breadboard
• 9V Battery
• Capacitors
• Resistors
• Jumper Wires
• Transistor
• Female audio input jack
• Audio cable
• Op amp
• Worksheet
*Light snacks

Technical details
Operational-amplifiers (Op-amps) are widely used in our everyday electronics. Op-amps can act as a amplifier. It can also pulse light as an oscillator. We will take a look at what an inverting and non-inverting op-amp is and how to calculate gain. We will also discuss what a direct circuit is and what an alternating circuit is. We will then make a speaker from a op-amp then connect the op-amp to a transistor to beat to your music.

Your Instructor
Jamie Lynn is a self-taught developer and engineer. She is also the co-founder of Breadboard Labs, a startup focused on teaching hardware to adults. 

All attendees are expected to abide by the Girl Develop It Code of Conduct.
