A: this chip is defined as a timer but it can be used for other reasons and applications.
Invented in 1970 by Hans R. Camenzind who was an electronics engineer from Switzerland, the 555 timer was first produced by Signetics in 1971.
A 556 IC is a dual 555 IC in one 14pin chip. With that said it composed of two timers capable of running in Astable, Bistable and Monostable modes. The 556 can be used as a function generator once the appropriate external components are connected. One note about using the 556/555 as a function generator is that you cannot achieve a perfect 50/50% duty cycle where the time on is equal to the time off, this is due the characteristics of the internal components having a different charge/discharge rates.
A Universal is a choice of words but this chip is widely used as a timer the accuracy for long elapse time is very good so that is widely used
PIC's are programmable microcontroller chips made by Microchip Inc. PIC's can be programmed to do timing functions, but they can do many other things as well. 555's are dedicated purpose timer chips made by several different manufacturers. They have no intelligence, they are strictly analog electronics.
The timer has to be multi-pole. The ballast must be connected to the load contacts of the timer. If the timer is a 120 Volt timer, the timer has to run on a 120V. circuit. Loads are loads, and as long as you have a multi-load timer you can hook up whatever you want. If the timer only works on a shared power source (load shares the timer supply) you will need to use a contactor on the load side or the timer.
556 is a dual version of 555 single timer.
is there a chip grant available for first timer buyers
its like a 555 timer chip. if you know wht that is

A 555 chip is used as a timer. In a monostable circuit the chip will send one pulse after a period of time. If the chip is in a astable circuit it will send pulses forever.

The 555 is not a sound chip, it is a general purpose programmable timer. As such, it is possible to program it to generate sounds or clock digital sound synthesizer chips.
556 * 556 = 309,136
Phones are different - mine resets to midnight. It depends on the settings of the timer chip.
A 555 timer is a chip that can be wired to different ways many different ways the main being a pulse generator it keeps repeating because it is pulsing the current on and off. this is used in burglar alarms ect
556 = 55,600%
70% of 556 is 389.2. Which means that 166.8 is 30% of 556.
