This kit is your hello-world to Controller Area Network protocol—you’ll send a message frame from one node to another, light an LED on receipt, and display live data on an OLED screen. Designed as a first CAN project, it demystifies differential signaling, message arbitration, and real-world protocol structure without overwhelming you.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou assemble two independent CAN nodes on breadboards. One node transmits a counter or a button-press command every second; the second node receives that message, toggles its onboard LED, and prints the value on a 0.96-inch OLED.
