hello everyone on the hood board had broken the power line and the varistor I changed them It lights up normally but has three speeds for the motor and an output for a 220 volt alternating lamp which are driven each by a triac T405Q and had a resistor 102 1000ohm pov were burnt I replaced them I put load the coil of a 220 volt relay but nothing works no output from 4 meters with base the negative pole of 5 volts I measure based on the negative pole of 5 volts at the edge of the resistor from the output of the microcontroller and extension to the gate of the triac but apparently the triac does not conduct does the load play a role i am thinking to use a fan 220 volt as load is better or it doesnt play role ? I just want to test it if it works because its motor is in another place and I will go there in a week.
the commands of the inputs working normal speed 1 choise 2 and 3 from buttons
microcontroller is ht48r05a
