This is a simple, subminiature size, axial lead mounted rectifier diode. Often used for reverse voltage protection, the 1N4001 is a staple for many power, DC to DC step up, and breadboard projects. The 1N4001 is rated for up to 1A/50V.
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!
This sensor uses an infrared emitted diode combined with an infrared phototransistor to detect the reflected infrared signal. Ideal for sensing black-to-white transitions or can be used to detect nearby objects (.5-1cm).
This is a very small light sensor. A photocell changes (also called a photodetector, photo resistor, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).
Use this simple IR receiver for infrared remote control of your next project. With low power consumption and an easy to use package, it mates well with embedded electronics and can be used with common IR remotes.
This is the same temperature sensor that is included in our SparkFun Inventor's Kit. The TMP36 is a low voltage, precision centigrade temperature sensor. It provides a voltage output that is linearly proportional to the Celsius temperature. It also doesn't require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range. We like it because it's so easy to use: Just give the device a ground and 2.7 to 5.5 VDC and read the voltage on the Vout pin. The output voltage can be converted to temperature easily using the scale factor of 10 mV/°C.
This is an incredibly simple two cell 18650 Battery Holder. When someone thinks of 18650 Cells they tend to think of flashlights first, which is fair since that is what they have been primarily used for. However, with this battery holder you will gain the ability to incorporate 18650 cells into applications like robotics or prototyping by simply dropping one into this device and attaching the leads, that's it.
This is the MyoWare Proto Shield, a simple proto-board for your MyoWare Muscle Sensor. With this shield you will be able to use the area provided to solder on whatever custom circuitry you can come up with. This shield provides 8 x 15 solderable through-holes on a standard 0.1" grid.
