Main component of this circuit is IC NE555 timer.IC1 in this circuit works in astable mode. Other components that are used in this circuit are resistor, capacitor, LEDs and transistor.When power supply is on and switch pressed then voltage at pin2 and pin6 of IC1 drops. At the same duration voltage at pin3 of IC1 gets high and LED glows.For driving big quantity of LEDs (say around 50), a PNP transistor T1 (BD140) linked in the output terminal of the circuit.In this circuit we have used only 9 LEDs. We have divided the 9 LEDs in the group of three LEDs which is attached with 82 ohm resistor.

In the previous two tutorials, we learned about VHDL basics and programs. Next, we’ll simulate and verify the VHDL programs.  To edit, compile, execute (simulate), or verify a VHDL program, there are requirements including software tools, such as: ISE from XILINX ModelSim from Mentor Graphics Riviera from Aldec Quartus-II from Altera etc.  All of these…

STMicroelectronics is extending its range of digital power-supply controllers with the STNRGPF02 for two-channel interleaved boost-PFC topologies. Now customers can easily configure the device using eDesignSuite software that also helps quickly complete the circuit design and select external components. The STNRGPF02 brings the advantages of digital power to applications from 600W to 6kW, including greater flexibility and…

Raspberry Pi is an amazing credit card-sized development board that can serve varied purposes for hackers, hobbyists, artists, as well as students. One of the most versatile application boards, it is believed that it can only be used for some common programming purposes especially the ones related to IoT or AI. In this blog, we will be breaking that myth and show you the versatility of this system and how it can make a difference to our lives in a long run. Let’s get on with it then.

STMicroelectronics, a global semiconductor company serving customers across the spectrum of electronics applications, is facilitating the modernization of battery-powered products to capture the advantages of the latest USB Power Delivery (USB PD) technology — including faster charging and easy reuse of USB-C chargers and cables. The universal fast-charging ecosystem is rapidly expanding as products like…

Vehicle is part of our busy life but if we are in office or in house then we need to park vehicle outside or in parking lot. There is prone to theft or hit by other vehicle. The situation of vehicle can’t be track without visiting parking place. So this project is built to track status of vehicle, when somebody try to steal the vehicle or get hit by any others vehicle.

The project built on two boards one is for transmission which named as PARKING VEHICLE MONITOR-TX and other is for receiving which named as PARKING VEHICLE MONITOR-RX. The TX board is used to transmit the status of vehicle and other RX board is used to receive the status of vehicle and display the status on 16×2 LCD display.
