We use barrel jacks a lot around here and sometimes we need to pop a switch into the mix. That usually means hacking up a perfectly good barrel jack extension cable, but the whole point of using the barrel jacks was so that we wouldn't have to hack things apart... Well, we found a solution: The Barrel Jack Power Switch.
Okay, it's nothing fancy but it is really useful. Plug your power supply into one end and the other into your project and, just like that, you've got a power switch! The on-off rocker switch has a good stiff 'click' to it, so it isn't easy to accidentally switch. it's also fairly small so it won't add too much unnecessary bulk to your project.
This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive male barrel jack. If you need to connect bare wires to a barrel jack on an Arduino or a development board, this might be the simple solution.
To facilitate the use of Raspberry Pi and screen module to work together, we specifically developed a simple adapter board and customized a batch of 26-pin (2X13) cable . Simply insert the screen module into the adapter board, then connect the board and Raspberry Pi plate with cable, thus the hardware connection is done, saving the trouble of...
The Fio v3 is a new spin on the Arduino Fio hardware powered by the ATmega32U4.Not only is it\'small and LiPo-ready, it\'s a very capable XBee-ready development board.
The JST-connector and 3.3v system voltage make this a great development tool for portable devices, simply plug in a Li-Poly battery and you\'re ready to go. Wireless sensor networks and...
Put a voltage meter anywhere with this very handy display. These are often used by RC hobbyists for keeping track of batteries but we thought it would be great on a breadboard or enclosure. This is the 2-wire version of the volt meter, two wires are used to power it and measure at the same time.
This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive female barrel jack. If you have a power supply with a barrel jack and want to plug it into a breadboard, this might be the simple solution.
Infrared proximity sensor made by Sharp. Part # GP2Y0A21YK has an analog output that varies from 3.1V at 10cm to 0.4V at 80cm. The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigtail below or soldering wires directly to the back of the module.
This is a row of 40 break away headers spaced 0.1" apart with long pins on both sides. This header is especially useful when you need to connect a PCB to a solderless breadboard. Each header can be broken apart to your preference to fit custom PCBs or general custom headers.
This is a Arduino compatible PS2 Joystick Module for Robot Projects. Simply connect to two analog inputs, the robot is at your commands with X,Y control. It also has a switch that is connected to a digital pin. This joystick module can be easily connect to Arduino by normal IO Expansion Shield with supplied cables.
No soldering required, Reusable...
it\'s a "soft touch" T18 RED knob that works great with our Panel Mount 10K and Panel Mount 100K potentiometers. The knob is designed to set directly on the potentiometer\'s ridges so it\'s an easy amp; secure fit. It has a nice feel, with a rubbery grip, tweaking it is quite fulfilling.
