For the past few years, students in my first semester calculus physics laboratory have explored kinematics (and also a little dynamics) by building and launching model rockets. Working in groups, the students build Estes Big Bertha or Baby Bertha rockets from kits. Then, we travel to a local park to launch the rockets. The rockets

If you are working on a project that responds to sounds, your circuit will require some type of microphone to transduce the sound into a modulated voltage and, most likely, some type of amplification of this modulated voltage. I like to use electret microphones to transduce sound because they require relatively simple circuits. For example,

The following schematic demonstrates a simple infrared (IR) photodiode circuit using a analog-to-digital converter (ADC) to monitor the photodiode. An analog pin on an Arduino used with the analogRead() function will do the job. Photodiodes are two-pin analog devices. This makes them relatively easy to use and makes their output graded. Some of my students
