SD cards are all over the place and they're great for storing large amounts of data. Why not take advantage by adding an SD socket to your next data heavy project. We use it on a whole bunch of our boards! The SD/MMC ( Secure Digital Disk / Multi Media Cards) cards use a very simple SPI serial bus as well as a 4-bit proprietary bus.

Have you ever wanted to control the flow of a liquid using your computer or microcontroller, but didn't know how? Well, here's how: The 12V solenoid controlled fluid valve. Simply connect a fluid source to the 3/4" threaded inlet and it will interrupt the flow until 12V is applied to the fast-on connectors on the solenoid. Note: This is not a gravity-feed solenoid. This means that you will need enough water pressure to fully open the valve. Check the datasheet below for exact details. It...

These small steppers are a great way to get things moving, especially when positioning and repeatability is a concern. When using a current limiting driver such as the Easydriver or Big Easydriver, a 12 volt power supply can be used as long as you adjust the current level to 400mA or less. If using a non current limited driver (like a L293D or an H-bridge) you will need to lower your input voltage to keep the motor current below 400mA. This is a Bipolar motor.

This buzzer is an add-on for your RedBot that gives your robot the ability to make awesome beep-boop noises or alerts when something interesting (or terrible) happens. The buzzer works by making use of two I/O pins on a controller board to create different noises based on the different frequency of I/O toggling. If you are using this buzzer on a RedBot, simply plug it in to one of the many 3-pin I/O ports and get your robot to make some noise. The buzzer has a 3-pin header which connects...

This is the fantastically easy to use sensor from Maxbotix. We are extremely pleased with the size, quality, and ease of use of this little range finder. The serial interface is a bit odd (it's RS232 instead of standard TTL), but the PWM and Analog interfaces will allow any micro to listen easily enough. The sensor provides very accurate readings of 0 to 255 inches (0 to 6.45m) in 1 inch increments with little or no dead zone! Maxbotix is offering the EZ0, EZ1, EZ2, EZ3, and EZ4 with...

A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove. I love the Nintendo Power Glove. It's so bad! The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend). Connector is 0.1" spaced and bread board friendly.
