  4. Connect the 3.3V VCC and GND to your breadboard. You need only to connect one GND but connecting all four will prevent you from accidently connecting them as Switches or LEDs.
  5. Wire your circuit to the Switches (SW7 to SW0) and LEDs (D7 to D0) according to the pinout of the Pico shown on this page. Don't forget to connect the 3.3V VCC and GND to your ICs

Example

We will test a 2 input AND gate using the 74HC08 in DIP. The notch on the package is used to locate pin 1. When the notch is on the left, pin 1 is the bottom left corner of the device.

We will make the following connections

Connect to the Pico, press the buttons SW0 and SW1 and observe D0. As expected, D0 will light up only with both SW0 and SW1 are on.
