Electronic Media Class Blog

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...
