Your email address will not be published. A lot of people desire so much to know the concepts of electronic circuit design from scratch. Any well-built electronic device has a manual. The main differences are power consumption and output drive current. Circuit … Nevertheless, there is no limit to what anyone can achieve if they are bent on doing so. This is because the energy (voltage) of the current at point A is bigger than the energy (Voltage) at point B. to understand this better watch this video tutorial. Circuit Designs with Common 74xx series and Analog Integrated Circuits. X ... Tutorials about Power Supply Design. CircuitsToday.com is an effort to provide free resources on electronics for electronic students and hobbyists. DISCHARGE TIME OF BATTERIES: Batteries are a great source to power up your circuit. Once you can handle designing simple circuits, you should proceed to more difficult ones and also learn circuit analysis. Overview. Once you’ve acquainted yourself with this rules and concepts of electronic circuit design and you have learnt the behavior of some electronic components, the next line of action will be to start your design, to do that you will need the following electronic components: The circuit we will design here is the simplest and commonest circuit a beginner starts with, it is a circuit that turns ON and OFF an LED, it is like writing “Hello world!” in computer programming  See the circuit diagram below: The battery supplies the electrical energy required to energize the circuit. More current will tend to flow through the least resistive in a circuit: Let’s say you already know what current and voltage is all about in electronics, if you have not, then read a comprehensive tutorial on that here. Once you have gained reasonable strength in non-programmable electronics, it is now time to delve into the use of Microcontrollers, like Arduino, or Raspberry pi. see the circuit diagram and simulation below: when you look at the simulation closely, you will see that more current is flowing through the path that has the 10k resistor than the path that has 100k resistor. Every circuit has resistance, resistance defines how current is distributed in a circuit. Online schematic capture lets hobbyists easily share and discuss their designs, while online circuit simulation allows for quick design iteration and accelerated learning about electronics. The transistors are manufactured in a variety of formats and can be obtained to fulfil a variety of roles from small signal to high power, and audio to RF and switching. As you practice circuit design, also try repairing some faulty devices, it helps to build the confidence, I have a mantra that says: “to be good at design, go and learn repairs”. Just as we know that water does not flow uphill. Once you are ready to carry out your simulation, watch the video below: I simulated how to turn ON and turn OFF an LED in the tutorial, it is a very simple tutorial. Amazon.com is one of my main sources for DIY electronics parts. figure 2 above shows bunch of colour-coded resistors. Unfortunately, that is not electronic circuit design.
