This is a simple 2-terminal microswitch, with a 36mm actuator. This switch has a great 'clicky' sound to it, and a nice tactile feel. We used these while lighting up a cupboard at home using led lighting. It can handle anything between...

Fingerprint scanners are awesome. Why use a key when you have one right at the tip of your finger? Unfortunately, they’re usually unreliable or difficult to implement. Well not anymore! We’ve found this great fingerprint module from...

Even though the Tron movies have been out for a while, electroluminescence is still the coolest thing since sliced bread. The only downer is carrying around a battery pack and bulky external inverter. Good news, we've found a slim...

This is a small force sensitive resistor. It has a 0.16" (4 mm) diameter active sensing area. This FSR from Interlink Electronics will vary its resistance depending on how much pressure is being applied to the sensing area. The harder...

This is a small device called a reed switch. When the device is exposed to a magnetic field, the two ferrous materials inside the switch pull together and the switch closes. When the magnetic field is removed, the reeds separate and the...

Put the pedal to the metal with this metal foot switch. This is the same kind of foot pedal you might find switching the power supply for a tattoo machine or as a sustain pedal on an electric piano. The non-slip pad on top and rubber...

This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year’s resolutions, and then forget about a month later). This sensor can measure up...

EL wire, or electroluminescent wire, is a flexible wire coated in phosphor. Apply the appropriate voltage and it lights up! It looks a lot like a thin flexible neon tube. They come in many bright colors (check below for other colors) and...

E-paper displays are rad. But those 26-pin SMD connectors can be a real pain to solder, so we put together a breakout board to help you integrate this very cool technology into your next project. This board breaks out all of the major...

This is a simple breakout board for the MQ - 3, MQ - 4, MQ - 6, MQ - 7, and MQ - 8 gas sensors. With the Gas Sensor Breakout you will be able to utilize each oversized, oddly spaced pins featured on every MQ gas sensor product. This is...

This is a breakout board for the SC16IS750, a handy chip used to convert I 2 C or SPI serial signals to a single-channel, high-performance UART. As an application example: we use this chip on our WiFly Shield to allow an Arduino to...

Have you ever needed to know if a voltage coming from a sensor is within a specific voltage window? This little breakout board allows you to hook up an analog signal, define your voltage window, and it will tell you (digitally - HIGH or...
