Topic: Interfacing a SSR relay to the arduino (Read 26506 times) previous topic - next topic


I  got the pic module pre-programmed to do serial LCD output (interfacing a hd47780).  The project is to control a popcorn popper to roast coffee.  I have a module that'll read the temperature every 1/8 second,  output to a computer (router), then my program calculate whether the heating element should be turned on or off.  the program then output the current time, temp, all that info through the pic to LCD, and use the pic's digital output to control the SSR.  When there is no load, everything seems to be fine.  when the SSR  starts to switch on/off, the pic starts to screw up (like sending out garbage to the LCD module, rebooting). I know my program is not sending garbage since it record everything that was sent to the pic. thanks for all the help
