Running your code
Once your code is on your Raspberry Pi, you'll want to switch to your SSH session and run the following, if you're using the source code from this book:
cd hands-on-robotics-with-javascript/ch2/blink-led
Otherwise, use cd to enter the folder where you stored your blink-led.js file on the Raspberry Pi. Then, run the following:
sudo node blink-led.js
Note that the Raspi-IO plugin requires you to run the command as sudo. If all has gone well, you should see a quickly blinking LED on your breadboard. If not, here are some troubleshooting steps:
- Check the wiring
- Double-check the wiring (seriously, 95% of the time it's a wiring issue)
- Make sure that the Node.js script did not experience an error on the Raspberry Pi
