components and pins

if it's possible, have a look at the datasheet

buzzer piezo componente Arduino

potenziometer componente Arduino

sensor Pir componente Arduino

matrix LED componente Arduino

transistor

*looking the little ball, from left to right... yellow black red, GND, 5V, segnale
Arduino

longest pin is positive

Vcc -> 5v
GND -> GND
TRIG is trigger
ECHO is the receiver

to central pin the signal

led
anode	+	longest pin		resistor and then 5V
cathode	-	shortest pin	look into the led, there is a little square on cathode	GRD
