This rubber ring is used to attach the ultrasonic sensor.

Electrolytic Condenser for use in rectifier circuits, power supplies and general electronic circuits. When connecting the Electrolytic Condenser, check the polarity of the terminals to prevent component damage. The larger terminal corresponds to the positive, and the smallest to the negative.

This Module of Switch Reed uses a Small Device called a Leaf Switch. When the Device is Exposed to a Magnetic Field, the Two Ferrous Materials within the Switch are joined together and the Switch closes. When the Magnetic Field is Removed, the Switch Opens.

The CNY70 has a compact construction where the emitter and receiver are arranged in the same direction to detect the presence of an object using the object's reflective IR beam.

This is an Arduino-Compatible B25 Voltage Sensor Module.

The imported PL2303HX controller can stabilize the flash at high speed. With a 500mA auto-recovery fuse for protection and two data transmission indicators that can monitor the data transfer status in real time. The entire board is coated with a high-quality transparent heat-shrinkable layer, rendering the PCB in a state of isolation from the outside, so that the board is not burned. Electrostatic package, ensures that the plate will not be damaged before use. Supports WIN7 system.

The Rotary Encoders are similar to Potentiometers, however, as they have no physical limits, they can run indefinitely. However, the similarity to a potentiometer is only physical, instead of having a variable resistance, in this type of Encoder we have an impulse output with 20 impulses per turn. In addition to the impulse output, it also has a push button function with two dedicated pins that close when we press the Encoder shaft.
