This one is a very simple but cool project, something that I would recommend to anyone who is interested into DIY electronics, gadgets and learning new stuff in general. It is definitely one of those projects that don’t require too much time but you can learn a lot by making it and also earn a lot of credit by sharing it with your friends and family.
Below you can see a final product. It’s a heart shaped, touch sensitive, keychain for your loved ones. On the front side there is a smiley face drawing that has eyes and mouth. Eyes have two red LEDs that will start to pulse once you touch the keychain or place you finger on the smiley face (see it in action below)
