LilyPad Buzzer
$6.50 $8.85  
2 pc(s)
This is a small buzzer for the LilyPad system. Use 2 I/O pins on the LilyPad main board and create different noises based on the different frequency of I/O toggling. Loud enough to hear inside a pocket but not obtrusively loud. Please note: This is an inductive buzzer meaning that is will act...

RFID Button - 16mm - 125kHz
$6.50  
4 pc(s)
This is a simple, thumbnail-size RFID tag. These tags are great for sensing presence, identification, etc., and they're small, so they can be easily sewn into clothing or inserted into enclosures. Each tag comes with a unique 32-bit ID code and is not reprogrammable. The carrier frequency of...

Momentary Push Button Switch - 12mm Square
$0.17 $0.35  
230 pc(s)
This is a standard 12mm square momentary button. What we really like is the large button head and good tactile feel (it 'clicks' really well). This button is great for user input on a PCB or a good, big reset button on a breadboard. Breadboard friendly!

Passive Buzzer - PCB Mount 12mm 2.048kHz
$0.50  
2030 pc(s)
This is a small 12mm round passive buzzer that operates around the audible 2kHz range. We drove it directly from a 3v to 5V Arduino or micro:bit to generate simple melody. Note : This passive buzzer requires a square wave (PWM) signal to make a sound or to play melodies. The frequency...

Force Sensitive Resistor - Small (FSR400) - Male Pin Header
$6.30 $9.00  
61 pc(s)
This is a small force sensitive resistor. It has a 0.16" (4 mm) diameter active sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR,...
