Last week our class made a prank handshake device. We made it from Little Bits which are a lot of electrical components. We built it from a battery, a switch, an extender, a buzzer and a button. It works when you press the button. It makes a noise from the buzzer. You wear it on your arm like it’s shown in the picture with the button hidden in the palm of your hand. The rest of the device is up your sleeve. When I shook my friend’s hand he squeezed the button and the buzzer made a noise.
