Electronic Media Class Blog

Today marks the end of the Sixteenth Week of Electronics Media. The end of the semester is right around the corner with only 2 days left until our project 2 critique. Here is what I have accomplished for this week. On 4/13/25, while I forgot to create a blog for that week, I did accomplish in gathering all the materials I needed: All the 3D parts that was listed on Week 14th for the Linear Motion Crank Shaft 37mm 600rpm geared DC motor 6mm shaft (https://www.amazon.com/dp/B0C7GN1VPD?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) Sparkfun Sound Detector (https://www.amazon.com/dp/B01B26UBYA?ref=ppx_yo2ov_dt_b_fed_asin_title) Gravity Voice Recognition Module (https://www.amazon.com/dp/B0C5XG3BXW?ref=ppx_yo2ov_dt_b_fed_asin_title) I used the day to also assemble the crank shaft and here is the assembled module: This is where space that will hold the motor and lever module. This is the shaft attached to the motor. On 4/22/25, I took the time to assemble these parts together and created a demo...

Today has marked the end of the Fourteenth Week of Electronics Media. A few weeks until the end of the semester and two weeks left until the end of our final project. Here is a recollection of all that I accomplished this week: On 4/8/25, I spent the time to research how I can have a motor create a vertical motion where I discovered three methods that could work well with the Arduino:   Linear Actuator: A slow high powered pole that is usually paired with servo motors from what I have gathered Crank Sliders: Nearly identical structure to the Linear Actuator but is specialized to push and is typically paired with a DC motor Pneumatic Cylinder: A high powered version of a Linear Actuator that requires compress gas I decided to opt in for Crank Sliders, as I was able to find a file for Crank Slider that specifies the type of DC motor to use on Thingiverse, and also the slimmer rod can have a spring attached at the top that could create the sort of Jack-In-The-Box motion I am stri...

The thirteenth week of electronics media has ended. For this week, we focused on understanding motors and discussing our project ideas. Here is a recap of all that occurred this week. On 3/31/25, I took the time to write down the notes from the labs before I got started on the motor examples. This is what I have recorded: What is a Base Resistor? The resistor that goes between the Arduino output pin and the base of the transistor  Keeps the transistor from drawing to much current What is a Flyback Diode? A diode that is installed "backwards" in a circuit to keep high-voltage spikes (transients) produced by inductive loads from traveling through the circuit and damaging sensitive components What is H-Bridge? A circuit that switches the polarity of 2 electrical contacts Looks like an H when made from scratch What is a Solenoid? A coil that when energized produces a controlled magnetic field down through its center, which in-turn pushes or pulls a metal plunger; easy way to make...
