This tiny 788BS 20 x 20mm Red LED Matrix is an excellent way to display data or create cool light patterns. Matrices like these are 'multiplexed' - so to control 64 LEDs you typically would only need 16 pins on your microcontroller or a driver chip, which would require even less.
The pins are 2.54mm / 0.100” breadboard pitch, and can be connected as shown in the attached diagram. ... [Read More]
Adding storage to a device using a microSD card is very common these days. Whether it is a data logging shield, a fancy microcontroller, or even a single board computer like the Raspberry Pi; they almost always use the microSD format.
This Kingston 32GB Class 10 card is nice and quick – rated at 10MB/s minimum data transfer rate and capable of reaching speeds of as high as 100MB/s. The card is compatible with both microSDHC and microSDXC host devices and will work with every microSD based data logger, breakout board, microcontroller, and single board computer we have in the shop!
As of April 16, 2020 we are now shipping a faster 100MB/s CANVAS Select Plus version.
Please Note: This card will not work with older microSD devices that lack SDHC support... [Read More]
This wired single pole single throw (SPST) On/Off button will latch on when pressed. To shut it off, simply press it again and it will release. The switch is pre-wired with two 18AWG leads measuring 120mm in length. The wired leads and enclosed connection make this ideal for wearable applications... [Read More]
Your electronics can now see in dazzling color with this lovely color light sensor. Adafruit found one of the best color sensors on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The filter means you'll get much truer color than most sensors, since humans don't see IR... [Read More]
Sending An Email With Attached Photo Using Python And The Raspberry Pi
We have already covered using a Raspberry Pi and Python to send an email containing basic text – but what if you wanted to attach a picture instead? In this tutorial we are going to adapt our code from our basic email tutorial to allow picture attachments to be sent. Interested? Head on over to the tutorial!
