MAX232 Pin Details

The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply MAX-232 voltage levels from a single 5-V supply. Each receiver converts MAX232 inputs to 5-Voltage TTL / CMOS levels. These receivers have a typical threshold of 1.3 V, a typical hysteresis of 0.5

CRO Means CATHODE  RAY OSCILLOSCOPE. CRT MEANS CATHODE RAY TUBE First time operation,  General information, Add-on modules(optional), Cro operation, components Tester, Maintenance, Service guide:  The TDS education oscilloscope series is designed specifically to meet the needs of today’s schools and universities. Packed with features and built-in tools, it is easy to learn and

How to test Electrolytic Capacitor

What is capacitor:-Capacitor is an electronic component that stores electric charge. The capacitor is made of 2 close conductors (usually plates) that are separated by a dielectric material. The plates accumulate electric charge when connected to power source. One plate accumulates positive charge and the other plate accumulates negative charge.

Astable Multivibrator using Transistor

   Astable, in which the circuit is not stable in either state it continually switches from one state to the other. It does not require an input such as a clock pulse.  This circuit operates 3v Dc. When apply 9v Dc add in series Resistor 470E value =220

Astable Multi-Vibrator Using 555 Timer IC

The multi-vibrator circuit having no stable state is called astable multi-vibrator. The circuit oscillates between two quasi-stable states. Hence it is also called as free-running multi vibrator. The astable circuits can be used in square wave, rectangular wave and ramp generator applications. The power supply voltage Vcc

Monostable Multivibrator using 555 Timer IC

A Monostable Multivibrator, often called a one-shot Multivibrator, is a pulse-generating circuit in which the duration of the pulse is determined by the RC network connected externally to the 555 timer. In a stable or stand by mode the output of the circuit is approximately Zero or
