Hello Kicad Forum!
I’m currently doing a project and i need arduino 5v relay for simulation in Kicad but unfortunately there is no relay module with input/trigger from arduino.
I have been searching for this so long and seems like i have to modify the existing relay in Kicad to attain this module. The problem is im using multiple relay like this so if i do like that my circuit will become complex
so i thought of modify the relay and make it into an symbol, so it will save space and less complex
Can anyone tell me how to convert my schematic into symbol or any relay module library with input/trigger
It’s not equivalent to a relay as it has three inputs: power and drive signal. Just make a rectangular symbol for it. And I don’t think there’s a simulation model for such a module. Why would you bother to simulate it? It’s a digital switch that’s all.
Exactly! this relay have 3 pins , the relay’s power closes on the trigger/signal from arduino which then energizes the coil. i need to control the relay with arduino for my project
As @retiredfeline writes above: you need to create your own symbol for the relay module.
The symbol will be a box with six pins. The two Power pins, the signal input pin, and the three output pins to the relay contacts.
At the moment you can’t turn a schematic into a symbol, that’s a later feature called design blocks. You can however make a hierarchical sheet out of a schematic. Or you want to treat the module as a black, er yellow, box, since it’s purchased whole, you can make a rectangular symbol where you don’t care about the internal circuitry. Making a symbol is documented:
You haven’t told us the version you are using. We are assuming v8 but making symbols hasn’t changed for many versions.
