Acumen Labware make 555 timers are highly stable integrated circuit capable of functioning as a free running multivibrator and an accurate time-delay generator.
When operational amplifier is being used as an oscillator the frequency and duty cycle are accurately controlled by only a capacitor and two external resistors. Some of its important features are, timing from micro-seconds through hours, trigger and reset inputs are logic compatible, monostable and astable operation, and output compatible with CMOS, DTL and TTL (when used with 5V supply)
The set-up consists of 555 IC which offers convenience of connection on board, a power supply, built-in facilities for various type of triggers-variable frequency, variable voltage, and manual. The resistors and capacitors required shall be fixed on the board.
Astable Mono Stable Multivibrator Using Timer Ic type
The following studies can be carried out
1. Operation as a monostable multivibrator
2. Operation as a free running multivibrator
3. Operation as a preset time delay
The above experiment has been put up on a printed bakelite board with an aim of providing an easy understanding to the students of schools and colleges. At Acumen Labware we make customized scientific kits/instruments for schools and colleges in which components are well spread out for clarity and easy maintenance. The set-up is provided with a user manual, which contains its detailed theory of operation, specifications and description of the various experiments that can be performed using it
