Your Arduino can tell you which countries you AREN’T in
A few months ago, Connor Nishijima demonstrated a neat project highlighting the Arduino Uno’s “built-in motion sensor.” Now, he’s using the Arduino Mega’s “built-in anti-GPS” to guess which countries you’re NOT in. How, you ask? By reading the frequency of the alternating current (AC) cycles in his house using an open analog pin. You’ll need an Arduino Mega […]
