Day 2 - Introductions to BreadBoard Ohm's law and Potentiometers
For this part of the lab a led light was assembled by connecting all of the components to a BreadBoard
An led such as the one shown in this picture was assembled to the breadboard. Furthermore, this resistor was used in the assembly. Next, there is a picture of a BreadBoard. Where the blue minus sign and red plus sign are located the components connect the BreadBoard connect horizontal in this picture; on the other hand, in this picture the holes that are next to the numbers are connected vertically in this picture. Now, using a separate BreadBoard, the led system was assembled. Power>Resistor>longer side of light bulb>ground
In this part of this day's lab we learned about continuity, resistance, and voltage measurements with the multimeter.
Ohm's law is V=I*R or Voltage=Current*Resistance
Here is a picture of the Potentiometer. OL means that there is no continuity or open loop. O stands for open and L means Loop. Open loop indicates that the positive and ground are not connected; therefore, this indicates that there is no connection where electricity can flow. This is very helpful when soldering a circuit board because it may lead to the discovery of bad soldering.
For the next part we attached the multimeter to a battery and measured the voltage of a battery. Notice that in the first picture the settings for the multimeter were on the continuity settings, which looks like a sound wave, and now they are on the voltage settings.
Furthermore, the wall's voltage was measured. Notice again that the settings for the multimeter are set to ac instead of dc.
Next, the resistance of several resistors were measured using the multimeter. In order to read the resistance the multimeter setting were changed, as shown in this picture, and the ground pin (black) was connected to one end of the resistor and the positive pin (red) was connected to another side of the resistor.
Also in this lab, the resistance of Light Dependent resistors were measured. Notice how in this video when light is exposed to the LDR the resistance decreases on the multimeter and when light is restricted from the LDR the resistance value is more high on the multimeter.
In addition the resistance was measured on the multimeter during the use of screw-variable resistor. In the video the current changes when the resistor is activated.
Furthermore, this resistor was used in the assembly.
