We have built a Scientific calculator having lots of functions like
Basic algebraic operations (+, -, *, %)
Trigonometric functions (SINe, COSine, TANgent)
Inverse trigonometric functions (arcSin, arcCos, arcTan)
Logarithmic function
Square root.
UPS is a system which converts DC to AC. So, UPS takes DC power of battery as input and gives AC power as output. Today we are going to build a 100 watt 12v DC to 220v AC inverter. This Circuit is simple and very useful.

Two LEDs can be seen through the standard plastic lid — one illuminates when the tilt switch is activated, the other flashes twice after a picture has been taken.

Some of these pins perform some special functions. With special GPIO put aside, we have 17 GPIO remaining.

Robots are a machine which reduces the human efforts in heavy works in industries, building etc. and makes life easy. Wwe are here with our next robot that is Mobile or DTMF Controlled Robot. DTMF controlled Robot runs over mobile DTMF technology that exists in Dial tone.

Here in this project we have implemented the concept of IoT and connected the Arduino robot with internet.

We can use oscilloscope to do the job, but not all of us can afford an oscilloscope. We can buy equipment for measuring the frequency but all these devices are costly and are not for everyone.

In fact, I started to play those classic Japanese game since I was a little boy, and right now I still feel interesting about it.
