Motion Detector Circuit using IR Sensor, 555 Working with
Aug 28, 2015Motion Detector Circuit Diagram: Motion Detector Circuit Explanation: The IR sensor will make the high frequency beam of 5 kHz with the help of 555timer which is set to astable multivibrator mode at the transmitter section. The IR sensor will produce the high frequency beam which is received by the photo resistor at the receiver section.
8051 Microcontroller Pin Diagram, Pin Description, Basic
Oct 10, 2017Now that we have seen the 8051 Microcontroller Pin Diagram and corresponding Pin Description, we will proceed to the basic circuit or schematic of the 8051 Microcontroller. The following image shows the basic circuit of the 8051 Microcontroller. This basic circuit of 8051 microcontroller is the minimal interface required for it to work.
100+ Power supply circuit diagram with PCB - ElecCircuit
Feb 17, 2021You often look at this circuit in many appliances. They are a quite old circuit, but so useful. Because It is very simple with just one transistor, Zener diode, and resistor. The output voltage depends on the Zener Diode. For example You want 12V supply, you use a 12V Zener diode. You can make it. I believe you! Continue Reading »
Drawing an Arduino Circuit Diagram - Use Arduino for Projects
May 07, 2016Here’s an example of a circuit using the Arduino Duemilanove and a 7 Segment Red LED 0.3″ Digital Display (RadioShack 276-075). Building this I was able to experiment with another feature of Fritzing, because the 7 Segment LED included in the core parts of the tool was a common anode numerical display.
JK Flip Flop Circuit Diagram in Proteus - The Engineering
Jan 26, 2021There are two types of JK Flip Flop named as: Basic JK Flip Flop. Master-Slave JK Flip Flop. Yet in this lesson, we'll make a clear idea about the Basic JK Flip Flop only best concepts, we'll not just observe the Circuit diagram of JK Flip Flop but we'll Construct a Circuit using different tools and Components in Proteus ISIS. We'll learn about the Formation of JK Flip Flop in two ways:
The CircuitCalculator Blog » PCB Trace Width Calculator
Aug 12, 2010I found your PCB calculator and thought it would be very useful for my next project. I am making a single layer circuit board and was trying to determine the line width for my circuit. However, I saw that the calculator shows amperage values for internal and external traces, and was unsure of the difference between them.
