We can make life a little easier for beginners to the Arduino world with this Bootloader Shield. It's easy to use, cheap and does the job nicely with ATmega328P DIP chips, ideal for breadboard experiments.
As an added bonus, because we're running at just 8Mhz (using the in-built oscillator) we can dispense with the crystal and two capacitors, which can just get in the way whilst we're experimenting.
Why would you need to upload a bootloader? Some reasons are mentioned in the video, but the most common one is to replace (or repair) a bootloader that has incorrect "fuse" settings and does not allow further sketches to be uploaded, or which runs the Arduino at the wrong speed.
And there's more! By understanding what the Bootloader is doing we can expand on the standard bootloader in future demos, making it really work for us. Or we can perhaps dispense with a bootloader - what does that mean for uploading sketches? Stay tuned!
