Unlike a standard wall outlet, this AC Power Outlet with Timer Circuit incorporates a built-in timer; as a result, it functions as a timer plug, also known as an outlet timer. Also, we can plug other device into it. Furthermore, a small chip called the 555 timer acts as the brain of the circuit, also […]

Tachometer Circuit
This easy to build Tachometer Circuit is a small DIY tool to check speed of rotating shaft or disc; we used tachometer to know how fast shaft or wheel spin in RPS (revolutions per second). Furthermore, this simple circuit uses two 7-segment displays and one slotted opto sensor MOC7811 where all parts are easy to […]
TV Remote Signal Jammer Circuit
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 […]
Analog to Digital Converter Circuit using IC 555
The easy way to change sensor voltage (analog) to digital (1 and 0) is by using Analog to Digital Converter Circuit using IC 555; as this method is cheap and easy for good learning. Here, IC 555 chip can make simple ADC with low cost and also in this circuit 555 IC work like ON/OFF […]
Frequency to Voltage Converter Circuit using IC 555
Input signal with some frequency goes into FVC (frequency to voltage converter) and output is DC voltage which matches that frequency. Furthermore, we can make Frequency to Voltage Converter Circuit using IC 555 in monostable mode and FVC is useful for many things where we need to check frequency like: Circuit Working: Parts List: Components […]
