My kids have a plastic farm toy. It moos, it oinks, it neighs, it
baas, and frankly, it grates. But since I tricked it out with an
attiny2313, at least it can play “Simon Says”.
This is what [Tom] said in his email to us. We love that when the toy annoyed [Tom], he improved it.
He started by inserting his own electronics. Using an ATTiny2313 for the brains, he proceeded to make it into an interesting game of “simon says”. Each stall is a button and has a nice bright LED in it to help you follow along. Interestingly, he preserved the original electronics as well and added a switch so he could change modes. Great job [Tom]!
