Hi all,
I am trying to make an animated relay work to switch on the bulb in my circuit. When a input is given to the pic16f877A, it is to make the relay on the bulb. I have fixed everything correctly( according to me...). But i can't make the relay work when i execute (F12). The lcd included works well though. Pls help. I will include the coding and the picture of the circuit. Also what do the blue and red square lights that appear in the proteus simulation.
Pls do help me.
Thanks

p.s
relay is set to 5V. It is still not working.
Do u notice the power terminal connected to one part of the relay and diode. Must have a certain value? I can't seem to insert any value.
Do u think that there is something wrong with the code in Mplab?
Must ac source and bulb be connected to the transistor and ground?
