Resistors, Simplified
Resistors are the most common part in electronics. They hold back current so LEDs don't burn out and turn voltages into signals a microcontroller can read.
Words to know
- Resistance
- Think of it like a narrow section of pipe.
- Resistor
- Think of it like a tap that sets how much water gets through.
- Potentiometer
- Think of it like a slider on a water slide that picks how high you start.
- LDR
- Think of it like a pipe that widens in sunlight.
- Tolerance
- Think of it like a 1 kg bag of rice that might weigh 950–1050 g.
