The 555 IC is used in this TV Remote Signal Jammer Circuit because it generates fake IR signals similar to a remote, as a result, the TV becomes confused. Furthermore, TV can not get the real remote signal, so we can watch the show without anyone changing the channel. Also, parts used to complete this […]
3V to 9V Dual Power Supply Circuit
The IC 555 works in an easy circuit that generates both positive and negative voltages from a single 3V source, such as two AA batteries; in addition, this circuit works well in a 3V to 9V dual power supply system. Moreover, IC 555 work as astable multivibrator in circuit and it make square wave again […]
Simple Voltage Follower Circuit using Op-amp IC 741
A Simple Voltage Follower Circuit using Op-amp IC 741 provides an output that matches the input; therefore, engineers also call it a buffer amplifier or a unity-gain amplifier. IC 741 op-amp is cheap and useful that is why so many people use it. Voltage follower has high input impedance and with low output impedance and […]
Analog to Digital Converter Circuit using IC 555
