This visual guide shows how your Arduino pins map to real-world use, and how they connect to a breadboard for prototyping. Click and zoom as needed!
Without soldering, you can try any circuit. Hook up sensors, buttons, LEDs, and resistors like Rick tests dangerous chemicals — quickly and with lots of yelling.
Use the side power rails for voltage and GND. Then build circuits row-by-row in the center zone. Try putting an LED + resistor combo between a digital pin and GND.
Once we build your first circuits, this will become your lab bench of glory.
