Timer Applications Using IC-555 Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12091
Indian Lab Suppliers supplies the Timer Applications Using IC-555 (Product ID: 12091) as part of its electronics engineering lab equipment range. It is a board with two 555 timers and a set of sensors for 13 timer, alarm, PWM and IR-link experiments.
Quick Answer
Experiments cover the 555 as a pulse generator, timer, sequential timer, PWM modulator, time-delay circuit and LED flasher; three burglar alarms (wire break with LDR, phototransistor or photodiode); light/dark detection with an LDR; a rain alarm; PWM speed control of a DC motor through an L293D driver; and an analog light-wave (IR) transmitter and receiver. Built-in sources include a negative-going pulser, a 2 kHz ±10% pulse generator, a 100 Hz ±10% sine generator and regulated 5 V and 9 V DC (100 mA). The component sections hold 22 resistors and a potentiometer, 11 capacitors, phototransistor, photodiode, LDR, IR LED, IR receiver module, rain sensor, two LEDs, diodes, three transistors, buzzer and switches. A 20 MHz CRO is needed alongside.
