Electronic control with an LDR
Ok, we have here another electronic circuit
00:00:00
With this circuit what we want to control is the amount of light this LED emits
00:00:04
And for that we have here the control component
00:00:13
It's a LDR, Light Dependent Resistor
00:00:19
That means that the resistance of the resistor depends on the amount of light we have in the environment
00:00:25
The more light we have, the less resistance the component has
00:00:34
And the less light, the more resistance
00:00:42
As an electric circuit, it is a simple electric circuit
00:00:47
the battery the current comes out of the battery through its positive terminal
00:00:51
goes through this wire through this line passes through this fixed resistor goes
00:00:59
through the LED and now goes to the LDR and comes back to the battery through
00:01:07
negative terminal let's see how it works here we have the same circuits so I'm going to simulate
00:01:16
the circuit now we don't have in theory any light so the LED is off as we increase the amount of
00:01:27
light as you can see the LED emits more light because the resistance of the LDR
00:01:42
is less than we have darkness in our environments then the more light the
00:01:57
The less resistance, so the more currents through the circuits.
00:02:07
The less light, the more resistance of this component, so the less currents through the
00:02:14
circuit, so the LED is, in theory, off.
00:02:21
And that's it.
