Hello. The relay module controls the 220V fluorescent lamp in Arduino. It has been confirmed that the lamp also operates whenever the relay module is switched on and off. But I want to put in a fuse holder because I want to control it while preventing overcurrent more safely, Is it okay to connect the circuit like this?? I'm currently using an Arduino unit3 compatible board. Below is the code used. void setup() { // put your setup code here, to run once: pinMode(9, OUTPUT); } void
