555 Timer IC The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The ic 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package. These 555 timer ICs are precision timing circuits capable of producing accurate time delays or oscillations. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by the use of the control voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low. The reset (RESET) input can override all other inputs and can be used to initiate a new timing cycle. When RESET goes low, the flip-flop is reset and the output goes low. When the output is low, a low-impedance path is provided between discharge (DISCH) and ground. The output circuit is capable of sinking or sourcing current up to 200 mA. The operation is specified for supplies of 5 V to 15 V. With a 5-V supply, output levels are compatible with TTL inputs. The NE555 is characterized for operation from 0°C to 70°C. This is characterized for operation from –40°C to 85°C. The NE555 is characterized for operation over the full military range of –55°C to 125°C. Features of the 555 timers are: Supply voltage between 4.5 and 18 volts. supply current 3 to 6 mA, and a Rise/Fall time of 100 nSec. IC 555 pin diagram The IC 555 is used in many circuits, for example, a One-shot pulse generator in Monostable mode as an Oscillator in Astable Mode or in Bistable mode to produce a flip/flop type action.

5K ohm 16mm Rotatory Variable Potentiometer Potentiometers are very useful in changing the electrical parameters of a system. It is a single turn 1K Potentiometer with a rotating knob. These potentiometers are also commonly called as a rotary potentiometer or just POT in short.  A potentiometer knob can also be used along with this POT for aesthetic purposes. This is a carbon track, single turn, adjustable resistances, of value 1KOhm Knob potentiometer. It is meant for mounting on panel and is supplied complete with a knob. The knob is affixed on the plastic spindle of the potentiometer and turns the spindle which changes the resistance. The variation of resistance is linearly proportion to the degree of rotation. Potentiometer, in electronic parlance, is a manually variable resistance. Because its most common consumer application is for controlling volume/tone of sound in broadcast receivers, it is loosely referred to as "volume" or ''tone''. It is not a meter with scale and needle. Potentiometers look different depending on size, power handled, application, value and type of material used. There is, however, a common feature-there is wiper which sweeps over a length of resistive material. The two ends of the resistive material as also the wiper are available to the user as electrical terminations. The user gets a variable resistance between the wiper and the two ends.
