Using popular IC 555 we can make Electronic Horn Circuit for cycle, alarm or fun use, as this Electronic Horn Circuit using IC 555 and one 8Ω speaker makes loud horn sound for car or alarm. Furthermore, one 555 IC work as astable multivibrator which means it make square wave by switching high and low […]
555 Timer Projects
AC Power Outlet with Timer Circuit
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 […]
