Thermal grease (also called CPU grease, heat paste, heat sink compound, heat sink paste, thermal compound, thermal gel, thermal interface material, or thermal paste) is a thermally conductive (but usually electrically insulating) compound, which is commonly used as an interface between heat sinks and heat sources such as high-power semiconductor devices. The main role of thermal grease is to eliminate air gaps or spaces (which act as thermal insulation) from the interface area in order to maximize heat transfer and dissipation.

The TL431 is three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors. These devices have a typical output impedance of 0.2 .
The TL494 device incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control circuit on a single chip. Designed primarily for power-supply control, this device offers the flexibility to tailor the power-supply control circuitry to a specific application. The TL494 device contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, a 5-V, 5%-precision regulator, and output-control circuits.The TL494C device is characterized for operation from 0C to 70C. The TL494I device is characterized for operation from 40C to 85C.
MG995 MG-995 Metal Gear Servo Motor Tower Pro-360 Degree comes complete with 30cm wire and 3 pins S type female header connector that fits most receivers, including Futaba, JR, GWS, Cirrus, Blue Bird, Blue Arrow, Corona, Berg, Spektrum, and Hitec. This high-speed standard servo can rotate approximately 360 degrees (60 in each direction). You can use any servo code, hardware, or library to control these servos, so its great for beginners who want to make stuff move without building a motor controller with feedback & gearbox, especially since it will fit in small places. The MG995 Metal Gear Servo also comes with a selection of arms and hardware to get you set up nice and fast.
A heat-sink is designed to remove heat from a transistor and dissipate it into the surrounding air as efficiently as possible. Heat-sinks take many different forms, such as finned aluminium or copper sheets or blocks, often painted or anodised matt black to help dissipate heat more quickly. Good physical contact between the transistor and heat-sink is essential, and a heat transmitting grease (heat-sink compound) is smeared on the contact area before clamping the transistor to the heat-sink.
A 6 Pin Push Switch also known as Mini DPDT Push Switch, is nothing but a combination of two push switches placed together inside one package. Unlike momentary switches which connect the wires of the switch only for a second, this switch retains its ON-OFF state till pushed later on. For example, if I push it once so that it’s turned on, it will remain in ON state till it’s pushed again. That’s why this switch is useful in controlling power connections most of the time.
The uA723 is a precision integrated-circuit voltage regulator, featuring high ripple rejection, excellent input and load regulation, excellent temperature stability, and low standby current. The circuit consists of a temperature-compensated reference-voltage amplifier, an error amplifier, a 150-mA output transistor, and an adjustable-output current limiter.The uA723 is characterized for operation from 0C to 70C.

ULN 2803 is a high-voltage, high-current Darlington transistor array. The device consists of eight npn Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of each Darlington pair is 500 mA. The Darlington pairs may be connected in parallel for higher current capability. Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.
This is ULN2003 Driver Module Stepper Motor Driver, small size and easy to use. It uses the ULN2003 driver chip to amplify the control signal from the Arduino. This Ultra Lightweight and cheap option commonly used to run and control the small applications stepper motors.
