MOT-ACT500 12VDC 500mm Stroke 900N 12 mm/s Aluminum Shaft Linear Actuator
US$113.70
This device is a heavy duty actuator that is capable of extending/retracting its arm with high amount of torque. It is powered via a large and powerful 12 VDC geared motor that allows for its arm to move back and forth. It can be used to open doors, windows, lift objects etc. Note: This actuator has a safety feature that prevents the arm from moving any further when reaching maximum or minimum length to prevent damaging the gears. Inverting the polarity allows you to change directions.

3105-ADA Mini Illuminated Momentary Pushbutton - Blue Power Symbol
US$3.00
This Mini Illuminated Momentary Power Button is an adorable breadboard-friendly tactile switch that has a built-in LED. It provides a simple way to add a tactile switch and a colorful universal power symbol to your project.  The tact switch is about the same size as 6mm tactile switches and can snap into a breadboard. There are an additional two pins that connect to the anode and cathode of a small LED that shines through the top. Note that this is a momentary button, not a on-off switch! Also, the LED is not connected to the switch in any way, and does not include a resistor. You'll need to add your own ~1K resistor and control the LED with a microcontroller pin or whatever you like.

DFR0523 Gravity: Digital Peristaltic Pump
US$97.93
Gravity: digital peristaltic pump is a new product developed by DFRobot. This is a new member of our water quality monitoring devices. It is an actuator for the liquid system. DFRobot peristaltic pump integrates a PPM motor driver on the pump, this is a Gravity interface (PH2.0-3P) motor driver. The control signal is compatible with standard servo motor, you can use Arduino, Raspberry Pi, micro:bit and other kinds of microcontrollers to control its direction and flow speed. The tube in the pump head is made up of BPT material, which is anti-acid and long life. Peristaltic pumps are a kind of positive displacement pump used for delivering small amounts of fluid. The fluid is contained within a flexible tube fitted inside a circular pump casing. When the rotor rotates continuously, the fluid in the tube will be squeezed and deliver to the other side. In this way, the liquid flow rate can be easily accuracy controlled.
