“IoT has been trending since long in the field of electronics and communications. Many projects, products are daily made under IoT. Even I made several projects under this topic. But this is the limit of how the IoT project can be shrinked in size without compromising it’s ability to work. This time I’m presenting you the smallest project of mine or the smallest project ever made in IoT field. There may be products which are way more smaller than my project, but I bet an IoT project can’t be smaller than the one which I have made. This is the simplest IoT project, IoT button with rechargeable battery having dimension of 4 x 2 x 1 cm. So let’s see how to make this.And their is also a surprise giveaway in the end.”
