LEDs are small powerful lights that can be used in any different situations.
In the code you can see that every second the light is being turned off and on again.
A potentiometer can power anything and at different voltages depending on how high on low you turn it.
In the code you can see are you turn the potentiometer higher it turns the LED on and at faster rates as you go higher. When you go lower it starts to turn the LED off.
RGBs are LEDs with three colors red, blue, and green that can be combined to make others colors too.
You can see in the coding that the RGB is being lit in the order of red then green.
Then in this code yellow and cyan.
In the video you can see the LEDs being lit one after the other and creating a pattern.
In this code you can see there is a 100 millisecond delay between every light being lit in order from 1 to 7.
In this code you can see the lights continuing but backwards from 7 to 1.
In the video you can see the photo resistor being touched and then not being touched. A photo resistor changes its resistance when the amount of light it receives changes.
This code shows up that when the photo resistor receives less light the LED gets bright. When the photo resistor receives more light the LED will shine lighter or not at all.
In the video you can see a temperature sensor. A temperature sensor is exactly what it sounds like it detects temperatures.
The code allows us to press on the sensor and make it hotter and it shows us how hot its getting and measures the temperature.
