This module is a self-locking switch. Press the button to turn it to the "on" state and press it again to turn it to the "off" state. The board has immersion gold plating and is compatible with the "gravity" 3-pin interface making it easy to connect to an Arduino I/O Expansion Shield.

Press to release pleasure! Our redesigned digital push buttons come with LED, immersion gold surface, and bright colored hats. A captital D at left corner indicates that it is a digital sensor. An illustration of button painted in the back notifying its function. Pressing it is a real fun, especially with the plastic cap off. The long pressable life also ensures its durability.

Ribbon cable is really helpful in situations where you need to make a lot of connections without a big mess of wires.

At sometime or another you may run out of pins on your Arduino board and need to extend it with shift registers. With this shift out module which is based on 74HC595. The datasheet refers to the 74HC595 as an "8-bit serial-in, serial or parallel-out shift register with output latches; 3-state." In other words, you can use it to control 8 outputs at a time while only taking up a few pins on your microcontroller. You can link multiple registers together to extend your output even more. It can also be applies to 51, AVR, PIC and other microcontroller.

Suitable for all kinds of circuit boards, sensors, mechanical support of the installation. They are great for building a multi-level robot chassis. This 10-pack of standoffs includes 10 sets screws and nuts for securing the top of the standoff to your project.
