Arduino Motion Detection Simple Project

https://youtu.be/zs6RBEWrAcI This is a very basic tutorial for Arduino beginners , we tried to keep it simple and to the point, how to use PIR motion detection sensors and how to control LED based on the sensor outpu. and so simply put,The main idea of this project is to light a number of LEDs after sensing a motion with the PIR Sensor, LEDs are going to be turned on with a specific color which here we chos ...

5 Must-Have Tools for Arduino Beginners

Arduino is an open-source electronics platform or board, as well as the software used. Arduino boards are meant to read an input and turn it into a corresponding output, such as turning a Twitter notification into an email notification should someone desire that functionality. Instructions are sent using the Arduino programming language and Arduino software. The main reason why Arduino has so much widesprea ...

Arduino Robot

first of all, i am sorry if i have grammar mistakes, i am asian and i am 13 years old, i study arduino by my self (mostly my self) and this is my first project and also my first instructables. this is the robot that i used to compete with my friends in soccer robot. i did some modifications when i used it but it is broken now, so what i show you here is just a smartphone control robot. i will upload the imp ...

RIDING THE NOSTALGIA TRAIN WITH A 6502 FROM THE GROUND UP

In the very early days of the PC revolution the only way to have a computer was to build one, sometimes from a kit but often from scratch. For the young, impoverished hobbyist, leafing through the pages of Popular Electronics was difficult, knowing that the revolution was passing you by. And just like that, the days of homebrewing drew to a close, forced into irrelevance by commodity beige boxes. ...

AppNote: Inverting DC/DC controller converts a positive input to a negative output with a single inductor

There are several ways to produce a negative voltage from a positive voltage source, including using a transformer or two inductors and/or multiple switches. However, none are as easy as using the LTC3863, which is elegant in its simplicity, has superior efficiency at light loads and reduces parts count compared to alternative solutions. Advanced Controller Capabilities The LTC3863 can produce a –0.4V to –1 ...

Power and Dependent Sources

Determine the power absorbed by the VCVS in the figure. Solution: The VCVS consists of an open circuit and a controlled-voltage source. There is no current in the open circuit, so no power is absorbed by the open circuit. The voltage vc across the open circuit is the controlling signal of the VCVS. The voltage Vc (across 2 ohm resisitor) measures vc to be vc = 2V. The voltage of the controlled voltage sourc ...

A combined MSF/DCF atomic clock receiver

For this to work you must obviously live in an area that can receive both signals. My circuit is based on two modules taken from two radio clocks bought at Lidl’s supermarket. Originally both were for the DCF clock but by substituting the original 77.5kHz crystal with a 60kHz crystal, one of the modules was converted to MSF. Notice that both antennas are lined up in my photograph. This is because Anthorn an ...

OurPCB – ‘What Are the Circuit Boards Made Of’

PCB boards are all around us in every gadget we use. Be it the smartphone or a simple calculator; their function depends on the performance of PCBs. Do you know what the PCB circuit boards made of are? PCB vs PCBA-What is the differences? What does a circuit board consist? We have prepared this helpful guide where you can learn about the materials used to make PCBs. You can also get a picture of how a manuf ...

Electronic Circuit Designing: Multitasking with Circuits (Part 4)

Step: 8) Find reusable modules from the circuit diagram Whenever we do hardware designing, the first rule is to make it in modules that can be reusable. The modules that we make for this particular project may come useful in another project and hence reduce the development time for that project. Even if a module is in use and at the same time found to be useful in another project, we can build another copy ...
