How to make Automatic ON LED Light with SCR

In this video i will show you how to Led light sensor using SCR
The term SCR stands for silicon controlled rectifier which is one of the most important members of the thyristor family.
It is more popular than the other Thyristors like TRIAC, SCS, DIAC, etc.
A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current-controlling device.
A silicon controlled rectifier (SCR) is a four-layer solid state current controlling device with 3 terminals.
They have anode and cathode terminals like a conventional diode and a third control terminal,
referred to as the Gate. SCRs are unidirectional devices, i.e. they conduct current only in one direction like a diode or rectifier.
SCRs are triggered only by currents going into the gate.
The SCR combines the rectifying features of diodes and the On - Off control features of transistors.
SCRs are generally used in power switching applications. In the normal OFF state, the device restricts current flow to the leakage current.
When the gate-to-cathode current exceeds a certain threshold,
the device turns ON and conducts current. The SCR will remain in the ON state even after gate current is removed
so long as the current through the device exceeds the holding current.
Once the current falls below the holding current for a period of time, the device will switch OFF.
If the gate is pulsed and the current through the device is below the latching current,
the device will remain in the OFF state.
in this video we will use Y1112 SCR same as c106 scr y1112 scr left to right 1st pin is a anode pin middles pin is a cathood pin and last pin is a gate pin.
we use some other components for this circuit like 1k ohms 1/4 watt resistor, 100k ohms variable resistor, LDR it mean light dependent resistor

Когда ты научишься правильно рисовать схемы?

😂

[@petrucorciu1967]

No entiendo nada y no puedo por favor si puedes traducir en español o si puedes enviar la esquema con circuito

Hello friend, this circuit can also be made with a 3 volt battery.??

[@kennmossman8701]

the SCR has a Vd

[@ABTabi]

You can try ,,,,,, if you have this one or any other ,,,,,

[@kennmossman8701]

When conducting, the SCR acts like a closed switch. The voltage drop will be approximately 0.7-1.8 V, depending on the size of the SCR and how much current is flowing through i

@@kennmossman8701 Actually, thank you for explaining to me, watching your videos, I learn and if I have to damage resistors, well, that's how you learn... thank you.

[@kennmossman8701]

why not explain What you want to do and Why. Are those 3V coin type battery

[@hasantamer9199]

good

[@ABTabi]

Thanks
