How to properly connect a trinistor to the GPIO RPi or MSP430 LaunchPad so as not to burn anything?

Question

Microcontrollers

Friends, I understand that the question is very primitive, but I just need only a push into a couple of URLs, because I just remember the basics of circuitry learned in childhood ... and my question is very simple.
I have a pair of thyristors (more precisely, trinistors) of the MCR100 type, 600 / 0.8A volts, through which I want to turn on LED garlands. I want to control thyristors via GPIO from Raspberry Pi or MSP430 LaunchPad (rather the latter). What kind of strapping do I need so as not to burn the debug board? And what to do with the land? just output one GPIO to the trinistor, and make the power supply of the garlands and the debug board independent?

Answer 1

well, the earth then definitely needs to be connected;)
in order not to burn - you can, for example, use an optocoupler.
and so - you can hang a low-power transistor on the GPIO to which you can already connect the thyristor
, but just the url about the Raspberry Pi and the control of the RGB LED strip
, and here is the document for the MSP430

Answer 2

Keywords "alternating current". The thyristor closes itself when current stops flowing through it. If you connect it to the DC circuit, then turn on, it will turn on, but will not turn off. You need a transistor. And it is better to open it through an optocoupler.
