Resistors are a good thing, in fact, they’re actually crucial in a lot of circuit designs. The only problem seems to be that resistors disappear into thin air. The only way to be sure that you’re gonna have the resistor you need when you...

This is your basic spool of lead free solder with a water soluble resin core. 0.031" gauge and 100 grams. This is a good spool for more advanced users that should last 6-12 months depending on how often you solder. If you are just...

This is a force sensitive resistor with a round, 0.5" diameter, 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...

This is the SparkFun Real Time Clock (RTC) Module, this little breakout that uses the DS1307 to keep track of the current year, month, day as well as the current time. The module comes fully assembled and includes a small CR1225 Lithium...

This is a simple-to-use hydrogen gas sensor, suitable for sensing hydrogen concentrations in the air. The MQ-8 can detect hydrogen gas concentrations anywhere from 100-10000ppm. This sensor has a high sensitivity and fast response time....

Here, for all your mechatronic needs, is a simple, high quality continuous rotation servo motor. This servo is able to take in 6 volts and deliver 30.6 oz-in. of maximum torque at 0.14 sec/60° A standard 3-pin power and control cable is...

This is the SparkFun GPS Shield Kit, a great launch pad for anyone looking to get into the world of GPS. This little kit includes our GPS Shield, an EM-506 GPS Receiver with interface cable, and a set of R3 headers to solder onto the...

Want to sound like a robot? The HT8950 is a single chip CMOS LSI voice modulator ICs which provide seven steps to shift the frequency of an input voice, producing a dramatic change in the output. The HT8950 provides two special effects:...

There’s nothing worse than getting ready for a good hack and then realizing that you can’t even get the box open because you don’t have the right screwdriver. Sure, we all have a few Phillips-head drivers and maybe a few slotted drivers...

This is a simple soldering iron stand composed of a heavy-duty metal base and a reinforced spring holder. The base and holder are detachable. A circular cleaning sponge, which has a nice home at the bottom of the base, is included. This...

The RHT03 (also known by DHT-22) is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and...

These DC powered heating pads are perfect for near-body heating applications. They get warm to the touch but not too hot as long as you provide the appropriate voltage. Simply apply 5VDC to the wire leads and within minutes, the pad will...
