I'm working with two MCP2515 CAN modules connected to Arduino Uno boards one as sender, one as receiver. CANH and CANL are linked between both modules, with 120Ω termination resistors at each end. Ground is shared. I’m attaching a snap of my setup I know it’s a bit messy and hard to follow .
I have verified my setup is working fine by uploading sender and receiver code code example from the mcp_can library and looking output on terminal. if anyone want to check code I can upload

I’d really appreciate your help in implement a simple two-node CAN setup with LED example as describe in my previous post #12.
