"What does the fox say?" I've liked that stupid song ever since my nieces played it for me. I thought it would be funny to make the weird sounds into a see n' say.
The electronics and code are very basic.
What challenged me the most was actually making new stickers for it. The fancy photo editing software I bought doesn't have curved text. The free version of Draftsight doesn't have curved text. Solidworks to the rescue.
I may improve this project later. I would use a smaller Arduino and shield to make room for a battery.
BTW, this is what the fox says: https://www.youtube.com/watch?v=J6NuhlibHsM
