Hello friends, I hope you all are doing great. Today, I am going to share the new Power LED Library for Proteus . A power LED is the LED of torches, bicycle lights, grow lights, spotlights and LED strips: a single emitter that takes a third or two thirds of an amp and gives a hundred or two hundred lumens, a hundred times the current of an indicator LED. That brings two problems an indicator LED never has. It gets hot, and its voltage changes as it does. Drive it the wrong way, or without a heatsink, and it fades, shifts and dies early.

Hello friends, I hope you all are doing great. Today, I am going to share the new Filament Bulb Library for Proteus . The incandescent bulb is the oldest electric light, and it is still everywhere: in the brake and indicator lights of millions of cars, in pilot lamps, in torches and in the hobby projects of anyone who wants a warm, simple light. It looks like the simplest load there is, just a piece of wire that glows, but it hides a surprise that destroys switches and fuses: when it is cold, it draws many times its rated current.

Hello friends, I hope you all are doing great. Today, I am going to share the new PC817 Optocoupler Library for Proteus . An optocoupler joins two circuits with nothing but light: an infrared LED on one side, a phototransistor on the other, and a clear gap between them that can hold off thousands of volts. It is how a 3.3 V or 5 V microcontroller reads a 24 V machine signal, how it switches a load on another supply without sharing its ground, and how a mains power supply tells its controller what the output is doing.

Hello friends, I hope you all are doing great. Today, I am going to share the new P-MOSFET Library for Proteus . The P-channel MOSFET is the switch of the high side: its source sits on the supply, the load hangs from its drain down to ground, and it connects or cuts the power to a whole circuit. It is how a battery-powered gadget switches its sensors off to save power, how a board protects itself against a reversed battery, and how a microcontroller turns on a 12 V load that must keep its ground connected.

Hello friends, I hope you all are doing great. Today, I am going to share the new N-MOSFET Library for Proteus . The N-channel MOSFET is the modern way to switch power from a microcontroller: its gate draws no steady current at all, it switches tens of amps with only milliohms of resistance, and it wastes far less power as heat than a bipolar transistor. It drives motors, LED strips, heaters, solenoids and whole power supplies.

Hello friends, I hope you all are doing great. Today, I am going to share the new TIP122 Darlington Library for Proteus . The TIP122 is the transistor almost every Arduino maker reaches for when a pin has to switch something big: a 12 V motor, a solenoid, an LED strip, a heater. It needs only a few milliamps on its base to carry amps through its collector, it comes in the sturdy TO-220 package that bolts onto a heatsink, and it costs very little.

Hello friends, I hope you all are doing great. Today, I am going to share the new Small Transistors Library for Proteus . The small bipolar transistor is the workhorse of electronics: it switches relays, motors and LEDs from a microcontroller pin, amplifies weak signals, drives speakers and buffers outputs. Four parts cover most of what hobbyists and students ever need, and those are the four in this library.

Hello friends, I hope you all are doing great. Today, I am going to share the new IR / UV LED Library for Proteus . Not every LED is meant to be seen. An infrared LED sends light just beyond red, invisible to us but perfect for remote controls, obstacle sensors and night cameras. An ultraviolet LED sends light just beyond violet, used to cure glue, check banknotes and make things glow in the dark. Both are ordinary 5 mm LEDs to wire up, and both behave a little differently from the coloured ones.

Hello friends, I hope you all are doing great. Today, I am going to share the new LED Bar Graph Library for Proteus . An LED bar graph is a row of ten small rectangular LEDs in one package, made to show a level at a glance: the volume of an amplifier, the charge of a battery, the speed of a fan, the signal of a radio. Light more bars for more level, or light a single bar as a moving pointer, and anyone can read it from across a room.

Hello friends, I hope you all are doing great. Today, I am going to share the new 7-Segment Display Library for Proteus . The 7-segment display is the classic way to show numbers: seven bars of light arranged as a figure eight, plus a decimal point. It is on alarm clocks, microwave ovens, fuel pumps, scoreboards, test meters and power supplies, and it is one of the first displays everyone learns to drive with an Arduino.
