Ce porte-piles permet de connecter 2 piles AAA en série pour alimenter toutes sortes de projets. Nous l'avons choisi parce que la boîte est très fine et que 2 piles AAA donnent environ 3 V pour les projets électroniques à faible tension. De plus, il est doté d'un interrupteur marche-arrêt très pratique. Convient à toute pile AAA standard. Lorsque vous utilisez des piles NiMH rechargeables, la tension de sortie varie d'environ 2,7V avec des piles chargées à 1,8V en fin de vie avec une tension nominale de 2,4V. Si vous utilisez des piles alcalines, la tension de sortie varie de 3,2 V avec des piles neuves à 2,2 V en fin de vie, avec une tension nominale d'environ 3V. La polarité correspond à celle de notre câble JST à 2 broches et des piles Li-Ion/Poly. Utilise un véritable connecteur JST afin qu'il ne s'accroche pas et ne se déchire pas dans les connecteurs JST. C'est une grande mise à jour pour les packs de batterie qui viennent avec micro:bit's parce qu'il a un interrupteur on-off intégré de sorte que vous n'avez pas à le tirer pour éteindre l'alimentation.

Perhaps you've been assembling a new robot friend, adding a computer for a brain and other fun personality touches. Now the time has come to let it leave the nest and fly on its own wings– err, wheels! These durable (but affordable!) plastic gearbox motors (also known as 'TT' motors) are an easy, low-cost way to get your projects moving. This is a TT DC Gearbox Motor with a gear ratio of 1:48, and it comes with 2 x 200mm wires with breadboard-friendly 0.1" male connectors. Perfect for plugging into a breadboard or terminal blocks. You can power these motors with 3VDC up to 6VDC, they'll of course go a little faster at the higher voltages. We grabbed one motor and found these stats when running it from a bench-top supply At 3VDC we measured 150mA @ 120 RPM no-load, and 1.1 Amps when stalled At 4.5VDC we measured 155mA @ 185 RPM no-load, and 1.2 Amps when stalled At 6VDC we measured 160mA @ 250 RPM no-load, and 1.5 Amps when stalled Note that these are very basic motors, and have no built-in encoders, speed control or positional feedback. Voltage goes in, rotation goes out! There will be variation from motor to motor, so a separate feedback system is required if you need precision movement.

This potentiometer is a two-in-one, good in a breadboard or with a panel. It's a fairly standard linear taper 10K ohm potentiometer, with a grippy shaft. It's smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2" apart with pin-points, so you can plug it into a breadboard or perfboard. Once you're done prototyping, you can drill a hole into your project box and mount the potentiometer that way.

These are standard '130 size' DC hobby motors. They come with a wider operating range than most toy motors: from 4.5 to 9VDC instead of 1.5-4.5V. This range makes them perfect for controlling with an Adafruit Motor Shield, or with an Arduino where you are more likely to have 5 or 9V available than a high current 3V setting. They'll fit in most electronics that already have 130-size motors installed and there's two breadboard-friendly wires soldered on already for fast prototyping.

This large (30mm diameter) piezo element is nicely enclosed with mounting holes so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tones and alerts AND you can use it as a sensor, to detect fast movements like knocks. You can also use it under a drum pad to make a drum/crash sensor It's rated for up to 12Vpp use but you can also use 3 or 5V square waves and its plenty loud. For music use with an Arduino, check out the Tone tutorial. For sensing, the Knock tutorial is your guide! There are thin wires attached, we plugged them into a solderless breadboard, but they might too thin to plug in directly into the Arduino socket headers.

This is a simple pack of five Yellow LilyPad LEDs that are still attached to one another, letting you snap the LEDs apart at your leisure to sew into clothing or whatever else you can dream up.   LilyPad is a wearable e-textile technology developed by Dr. Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad piece was creatively designed with large sew tabs to allow them to be sewn into fabric. Various input, output, power and sensor boards are available. They're even washable (with special care)!   Note: A portion of this sale is given back to Dr. Buechley for continued development and education in e-textiles.

This 3x AA battery, switched battery holder come compete with a terminal connector on the end of the wires. These are perfect for connecting LEDs without the need for soldering. The batteries are fully enclosed in plastic case, which is secured in place by a small screw. The unit incorporates a small on / off switch. The leads are approximately 130mm in length and colour red and black to show the polarity of the connector.

This 5mm RGB LED contains three LED elements (red, green and blue). Each element can be controlled independently. By varying the amount by which each element is turned on any colour can be created. They are ideal for designing variable coloured lighting effects. This LED has a common cathode which is the longest leg (negative). Features: Diffused LED for even light output. RoHS compliant. Contents: 1 x RGB 5mm Diffused LED - 60deg - 1000mCd - Cmn Cathode.

This is the LilyPad Rainbow LED strip, with seven LilyPad LEDs that are still attached to one another, letting you snap LEDs apart at your leisure to sew into clothing or whatever else you can dream up. The LilyPad Rainbow LED features seven individual LEDs in six unique colors (Red, Blue, Green, Yellow, Pink, and White). Text has been added to the back of each board to indicate its color. Due to popular request, we have included two white LEDs instead of just one. Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education in e-textiles.

High-quality A/B grade American Maple MDF panel measuring 300mm x 200mm. Ideal for structural projects requiring a high-quality appearance and finish on both the topside and panelling. Suitable for laser cutting. This MDF panel is veneered on both faces of the sheet: A grade veneer on the front and B grade on the reverse. Please note:As wood is a natural product, there is often a crook or bow to the sheet. The natural twist might be in excess of 10mm (see below - Tolerances and Caution) .A wood veneer is not like an artificial surface such as melamine or a laminate. It is cut from the log and therefore has its own unique grain, texture, and colour. A Grade Veneer is a very high-quality grading (typically the best you will see). The surface of the material will be consistent in appearance with no large variations in colour. Small pin knots are allowed and these would typically be only a few mm in diameter. This grade veneer is on the topside of this MDF sheet. The B Grade Veneer underside shows the natural look of the veneer. There will be changes in colour that show the grain pattern. Sound, smooth knots are allowed and these will typically be under 15mm to 35mm in diameter (depending on the countries grading rules). The surface should normally be free from open knots and plugs. The material should be suitable for paint/stain or a lacquered finish. There are two different cuts that can be used in veneer production: 'Quarter Cut' are cut at 90 degrees, producing the effect of a straight grain.'Crown Cut' are sliced through the log, producing 'Crowns' and adding more character to the finish (as used on this product).This product conforms to E1 (low) formaldehyde levels and is often described as 'Laser Grade' MDF but there is no official classification for this. We believe that E1 conforming MDF is the safest and best MDF for using in a laser cutter. Features:A/B grade American Maple finish.Veneer thickness approximately 0.5mm.High-quality wood and veneer, for great-looking finishes.MDF core.Suitable for use in internal dry conditions as defined in EN 622 parts 1 and 5 and conforms to EN13986.Low formaldehyde emissions.Contents:1 x 4mm American Maple MDF, 300mm x 200mm Sheet.Dimensions: Length: 300mm.
