AVR with SCR
It is not a Tiny26, but a Mega328P. I wrote it in a post before, in my schematic editor there were no mega328p. The pickup contains voltage regulator and some other part, to...

AVR with SCR
Thanks your reply Kartman! I edited the above circuit cause I totally forgot that I supply my device with 3.3V. So to sum:  My uC is an ATMEGA328P. I fires the scr with the...

AVR with SCR
The out pin goes to a transformer, which amplify the voltage to make spark. I think I forgot to say that I want to use this circuit as a CDI.   I forgot, that I supply my AVr...

AVR with SCR
I attached a schematic from the SCR. The big question from me, that how to calculate the value for the gate resistor in this form? (On the schematic I marked it with "100??").

AVR with SCR
UPDATE! I tested my circuit with TIC106M SCR. The AVR supply voltage is 4.39V. The voltage on the I/O pin, which "fires" the SCR is 2.7V. Refer to the datasheet (Igt=60-200uA, Vgt...

Thank you! Does these parameters are actually in the datasheet as like gate trigger voltage and gate trigger current?

Thanks your remark, you are right.

AVR with SCR
Thank you! If you divide 4.3 with 0.01 the result is 430 Ohm so the formula or the result is wrong?

AVR with SCR
I know I can't switch the thyristor via the avr. I "switch it off" with the help of a resistor between gnd and the gate.
