Here is a simple tilt sensor based switch circuit diagram which is built using a mercury based tilt sensor. This sensor is place on a box, so when someone opens the box, the buzzer connected with the ...

In this article, we will make a buck converter using 555 timer IC and a IRFZ44N N channel MOSFET and use it as LED dimmer circuit or as a motor speed controller circuit. This circuit is basically a ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be ...

Learn how to use logic gates and circuit diagrams to create a simple calculator that can perform addition and subtraction with four-bit numbers.

A simple external switches and LEDs panel to manage some FS2020 (for PC) airplanes commands. If you are a Flight Simulator enthusiast and would try to build your first external panel to send some ...

In this circuit the LED and switch are both connected with the same I/O pin. But the led stays burning when the switch is operated. Only 3 resistors are used. One common wire is going to every switch ...

PM-BLDC Motor based drive is simple, reliable and most widely used drive for Electric Vehicle (EV) applications. This paper proposes the fault diagnostic method to detect switch fault in PM-BLDC motor ...

The wireless switch circuit described here requires no physical contact for operating the appliance. You just need to move your hand between the IR LED and the photo-transistor. The infrared rays ...

Buzzer Horrible Science fact It's all well and good having a perfect, simple circuit but it it includes a switch, it will only work if the switch is in the on position meaning the circuit is closed.

If you switch to either of these, you can make a worthwhile saving, but switching to all LED bulbs, you could save as much as £400 on your energy bill this year.

In this class, you will learn how to use an Arduino in simple projects. We will cover programming and the simple electronic circuits needed to connect an Arduino to LEDs, switches and dials in order ...
