I bought my son a electronics snap kit about 2 years ago, and quickly completed some projects that were in the included book. This was fun for us, a good start, but there was more. I began teaching him about series and parallel circuits, passive components, and different types of sensors. I then said, “Without looking at the book, build a flashlight. OK, good, now build a fan with a switchable light. OK, now build a…” Continue reading →
So, you have just made an awesome gadget using an Arduino. You love it. OH! wait, you just got another idea for a different great project! But then.. you have to take your old one apart.. Is there a way to have more than one Arduino project without having more than one Arduino?
Yes, by putting you project on a bread board, you can accomplish this task, as well as saving some coin and earning the bragging rights of building it yourself. The video above explains about how to do that. An Atmel ATmega328 IC will serve you greatly. All that is needed is the ATmega IC and a few external components, a crystal, a few ceramic caps, and an FTDI Friend or FTDI Cable interface.
The purpose of doing this is so you can develop more than one project at a time without having to buy additional Arduino’s, and the second is to test a circuit for production. Remember, and Arduino has a lot of handy circuitry on it that you might not want on your project. For example, you might not need power switching, ICSP header, or FTDI/8U2 circuitry. Transferring your project to a breadboard will allow you to see how your project will run with the ‘bare essentials’.
The circuit is surprisingly simple, so if you haven’t tried it, build a stand alone project. Adafruit even has great Arduino stickers so you can quickly and easily identify the pins. Below is a pin reference image. Happy building, it’s a lot of fun! Continue reading →
