How to use a scr with arduino?
It takes less than 1V to trigger an SCR so you can trigger it directly from an Arduino, but you''d need a resistor (something 1K) to protect the Arduino from excess current.
Circuit design SCR trigger with optocoupler
As a power SCR I thought of using the TYN812 that triggers starting from 10 mA with an IGM of 1.5 A. For the optocoupler I have the MOC3023 with ISTM of 1 A for 1 ms.

Optocoupler to SCR gate interfacing | Forum for Electronics
Besides the already discussed voltage rating problem, it''s unlikely that a BJT optocoupler can source the required trigger current. In so far the design is not feasible.
Silicon-Controlled Rectifier | SCR Modules | Littelfuse
Our SCR devices activate with minimal gate current and feature fast turn-off capabilities, reducing the risk of commutation failure. Common applications include strobe lights, fluid level sensors, and
Optocoupler Tutorial for Beginners
SCRs are capable of handling large currents and voltages, making photo-SCR optocouplers ideal for controlling power in AC and DC systems. This device is similar to photo-SCR
