Wiring
Let us follow the direction of the current to build the circuit!
1. Here we use the electrical signal from the GP15 pin of the Pico board to make the LED work, and the circuit
starts from here.
2. The current needs to pass through a 220 ohm resistor (used to protect the LED). Insert one end (either end) of
the resistor into the same row as the Pico GP15 pin (row 20 in my circuit), and insert the other end into the free
row of the breadboard (row 24 in my circuit).
Note: The color ring of the 220 ohm resistor is red, red, black, black and brown.
3. Pick up the LED, you will see that one of its leads is longer than the other. Insert the longer lead into the same
row as the end of the resistor, and connect the shorter lead across the middle gap of the breadboard to the same
row.
Note:
The longer lead is known as the anode, and represents the positive side of the circuit; the
shorter lead is the cathode, and represents the negative side.
The anode needs to be connected to the GPIO pin through a resistor; the cathode needs to be con-
nected to the GND pin.
4. Insert the male-to-male (M2M) jumper wire into the same row as the LED short pin, and then connect it to the
negative power bus of the breadboard.
5. Use a jumper to connect the negative power bus to the GND pin of Pico.
