For the group assignment, I didn’t have a proper place to carry out the activity, so I contacted a friend, Omar, who had the necessary equipment at his house. He has been helping me with some of the equipment he owns and with key concepts to better understand electronics. This helped me a lot, as he had the equipment required for the assignment, which allowed me to see its utility and gain a clearer understanding of various aspects of electronics.
I currently work at Fab Lab iFurniture as a Fab Manager, so whenever we have visitors or organize training sessions, I am responsible for leading this workshop on risk prevention and workplace safety. For this reason, I have organized a group invitation to my colleagues from Fab Academy to participate in this workshop.
What is displayed on the screen is the result of configuring the LED to trigger every 0.1 seconds. Each pulse or square on the screen represents 100 millivolts. In my LED, the voltage is 200 millivolts, so each square represents 50 milliseconds. In practice, I have 2 squares, which equal 100 milliseconds.
In the signal analysis, the Pk-Pk (peak-to-peak) value I obtained is 212.00 mV. The sampling rate is 20.0 MSa/s (million samples per second), with a memory depth of 14.0 Mpts (million points per channel). This indicates that the oscilloscope is sampling at a high rate and has sufficient memory capacity to capture complex and high-resolution signals.
For this exercise, the microcontroller must be connected to a power source in order to use the oscilloscope. This is necessary because the oscilloscope measures the electrical signals generated by the microcontroller, and it needs the microcontroller to be active and functioning in order to obtain accurate readings.
Now I will use the multimeter to measure the resistance. For this, the component must be disconnected from the power source to make an accurate measurement. The reading obtained in ohms is 217.07 Ω.
To measure the LED, it must be connected to a power source. Then, we perform the same process with the multimeter, and the reading obtained was 0.94 V. This value corresponds to the voltage drop across the LED when it is operating. The LED typically has a voltage drop that varies depending on its type and color. In this case, the 0.94 V reading indicates that the LED is functioning correctly within the expected range, as the typical voltage drop of common LEDs is usually between 1.8 V and 3.2 V, depending on the type of LED.
