About the Pushbutton LED CircuitThe switch, by default, is open, meaning no current can get through. When you push the button, the circuit closes, allowing current to pass through and light the LED.
Diagram explaining the NPN and PNP in our motor circuitthe pnps and the npns are opposite if the pnp gets power it opens and when the npn doesn't get power it opens so the switches either give power or not to the transistors
Turn On Switch - How It Workswhen you turn on the switch, one part of the segmented LED turns on. the resistor is attached on the bottom bus but not shared between the pins.
How the resistor affects when the LED lights upwhen we swapped the resistor, it made a difference in when the LED lit. the resistor we added is stronger then the other one so the LED stays unlit longer.
Why can't we see infrared?we can not see infrared because that is the only type of light energy that our eyes are not sensitive to.
Introducing The Potentiometera potentiometer has three prongs. two are connected to the resistance part. one is connected the switch. which controls the resistance.
