Science Buddies: "Ask an Expert"

Hello, I am currently working on a project known as, "Build a Robotic Arm" and I am stuck on the coding section. I used the figure 7 example for the wiring and downloaded the example code to a new sketch in the arduino website. However, when i verify the code there are always errors with it. Am I doing bleep wrong? If so, is there any way i can fix it. Thank you.

What do the errors actually say?

Please upload a photo or two showing your circuit straight on and as clear as possible so that someone can take a look. The code doesn’t require any modification, but if you can take a screenshot showing the error and the code above it that may be helpful.

One thing to check is to ensure that you have the board selected. Check “Tools -> Port” in the Arduino IDE and make sure the Arduino is listed with a COM port (on Windows; it will be bleep like “cu.usb” on Mac). If it isn’t showing up there, the Arduino is not being detected.
