Have you ever wanted to start your widget the same way you start your car? These key switches are the key to making that happen. This simple ON-OFF switch can be used to power up your project with the turn of a key. Two large (2mm x 4.5mm) solder lugs on the back make connecting wires easy.
Wire it up just like a potentiometer and use serial signals to 'turn the knob.' Another handy feature of digital potentiometers is that because they aren't controlled mechanically, they don't have a pre-determined sweep profile.In other words, depending on the way you write your code the potentiometer can 'sweep' in a linear fashion, a logarithmic fashion, or according to any other profile you like. Digital potentiometers can also be used in conjunction with rotary encoders to consolidate large banks of potentiometers into one 'smart' rotary control.
This is the basic L7805 voltage regulator, a three-terminal positive regulator with a 5V fixed output voltage. This fixed regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Each one of these voltage regulators can output a max current of 1.5A.
Disc Neodym Magnets 6x3 mm are composed of Neodymium/Iron/Boron (NdFeB), these magnets are curiously strong and make for a great way to attach tools to a metal workbench, hold small children to a fridge, and as a trigger for reed switches.
Standard IC Wire Wrap DIP Sockets. Extended leads allow for multiple wire wrap connections for prototyping. This is a 300mil 8-pin Socket. Check the related items for more wire wrap Sockets in different widths and pin counts.
In secure embedded systems, you often need to authenticate messages or connected devices but many microcontrollers aren\'t set up for the necessary cryptography. That\'s where the Atmel ATSHA204 comes in.
LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays.
This is a very basic 5mm LED with a green lens. It has a typical forward voltage of 2.0V and a rated forward current of 20mA.
The PowerCell board is a single cell LiPo boost converter (to 3.3V and 5V) and micro-USB charger in one. The board comes with a JST connector for a single cell LiPo battery, a micro-USB connector for the 5V charge input, and selectable 3.3V and 5V output pins (labeled \'out\'). There are also two charge pins broken out (labeled \'charge\'), so you can...
Level shifting chips let you connect 3V and 5V devices together safely. This chip is similar to others in the shop (such as the 74LVC125) except this one is particularly good at converting 3V logic up to 5V . This is in demand especially when connecting some 3V devices such as the Teensy 3 to NeoPixels! Just power the 74AHCT125 with 5V, it...
Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6" (66mm) outer diameter. The rings are \'chainable\' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the...
