A few days back, here on CG, we introduced an astable frequency calculator tool, and the response we got from that motivated us to present a similar one for monostable too. A monostable multivibrator is a triggerable pulse generator that produces a single pulse upon receiving a trigger. Previously we published a wonderful article describing … [Read more...] about 555 Timer Monostable Calculator for Monostable Multivibrator

555 Touch Sensor
How to make a touch sensor? Here is a simple DIY touch sensor circuit diagram using 555 timer monostable mode. The touch switch is only a conducting metal sheet that acts as a touch sensor. The 555 touch switch is not a touch capacitive sensor; it is only a metal touch sensor button. Using this you can turn on and off devices with a single … [Read more...] about 555 Touch Sensor
Low Pass Filter | Integrator Circuit Using Op Amp 741
Here we are opening the door to a very wide range of useful and exciting applications of the opamp. Here we are discussing an opamp RC circuit named as opamp integrator circuit. This circuit simply performs the integration of the input waveform. Circuit Diagram of Low Pass Filter Components Required Resistors (10kΩ, 15kΩ)Capacitor (0.01µF x 2)Op-amp 741 x … [Read more...] about Low Pass Filter | Integrator Circuit Using Op Amp 741
Op Amp 741 Non Inverting Amplifier Circuit With Simulated Waveform
The non-inverting amplifier is one of the most popular op-amp circuits similar to the op-amp inverting amplifier circuit. It provides a gain to the input signal without any change in the polarity. If a sine wave is fed to the input of this op-amp noninverting amplifier, the output will be an amplified sine wave with zero phase shift. Here the input is … [Read more...] about Op Amp 741 Non Inverting Amplifier Circuit With Simulated Waveform
Remote Controlled DC Motor for Toy Car Circuit Diagram
This is a simple hobby circuit of a remote controlled toy car. The main component used here is the IR sensor circuit consisting of TSOP. Using a TSOP IR receiver we can start and stop the DC motor vehicle. However this circuit has a small disadvantage that it can’t control the speed of DC car motor, rather it ON and OFF the small dc motors. Thus it is … [Read more...] about Remote Controlled DC Motor for Toy Car Circuit Diagram
