• Breadboard, LEDs and Resistors
• Building a circuit on a breadboard
• Delete and select sprites
• Switching costumes
• Set a limited number of repeat loops
4.4.3 Build the Circuit
Follow the diagram below to build the circuit on the breadboard.
Since the anode of the LED (the longer pin) is connected to pin26 through a 220 resistor, and the cathode of the LED
is connected to GND, you can light up the LED by giving pin 9 a high level.
