These clips are great for protecting your fingers whilst assembling sewing projects. Why limit yourself to fabric though, we could also see them coming in useful for papercraft projects, taming uncooperative cables or combining with some string to make a snazzy photo display.

They come in a handy storage tub with 100 clips in a mix of 8 colours (pink, red, orange, yellow, green, blue, purple and clear). The flat side of the clips has guide markings 5, 7 and 10mm in from the edge, which helps keep your seams precisely lined up.

Specifications

• Width: 10mm
• Length: 27mm
• Clip thickness (fully open): approx. 90mm

Add touch control to your electronics projects in seconds! The BMT Capacitive Touch Module is a "plug-and-play" sensor that works just like a smartphone screen. With just three pins (VCC, GND, and Signal), it is incredibly easy to wire to any microcontroller. It replaces old-fashioned clicky buttons with a modern touch surface that never wears out. Perfect for school projects, smart mirrors, and custom LED controllers!

Features

• Touch sensor module sensor
• When touching, S outputs a high; touch again, S will output low
• Power Range: 3-5V
• Current: 5MA
• Interface: G (GND), V (vcc), S (signal)

If you own an Arduino UNO R3, you might need this case/enclosure :) This is pretty simple yet practical casing designed for Arduino UNO. It offers plenty of inner space, and if you need to access the GPIO of Arduino UNO, the top cover has an opening for it. It is perfect casing for educator, beginner, or maker that need to access the GPIO. With its transparent color and build using ABS to provide rugged protection to your Arduino UNO.

The case comes in two parts so you can simply snap it together, no screws or nuts needed. There is a base plane, where you should place the Arduino UNO board. Arduino UNO fit into the base plane nicely, no screw is needed to secure the Arduino. The best part for this enclosure is you can access all the pins and ports on the Arduino UNO. This case suitable for Arduino Uno Rev3 and also Uno Compatible (CH340).

Note: If you want to use this case with Arduino Uno Rev3, you need to remove the base first before putting it into this case.

Features

• Protective case designed specifically for Arduino Uno R3.
• The case is a two-piece injection-molded that snaps together around for Arduino. Holds the board firmly in place.
• It provides tough protection for Arduino UNO while providing access to all connectors.
• Easy access to each header, USB port, power jack, the reset button, etc.
• Includes reset key for use with the Uno's reset button. Secondary screw-mounting points for securing for Arduino.

Note: Arduino UNO board not included in the packing list.

Specifications

• Colour: Transparent
• Material: ABS
• Product Size: Approx. 7.5cm x 6cm x 1.7cm
• Weight: About 25g

Note: Not Suitable to open and close the case frequently (Clip may break easily). It may be softer than normal ABS casing.
