KJ ELECTRONICS

Hello there, There is only one possibility to get the solution out you have missed the data wires of the IC 4017 OR the row controller ic make sure all the connections are as given in the circuit diagram. By looking at the photo it is clear that only data and latch wires are missed or wrongly connected

Already completed the part 2 of this series you can visit that through the instructables or through the profile

No worries try until you get success and hope you will get it never panic at the first stage

thanks you

sunburn xD and it was just the matter or vu or flipped one uv meter :-)

sunburn xD and it was just the matter vu or flipped one vu meter :-)

the part 2 or this series has been released https://www.instructables.com/UV-METER-Part-2-U...

there are two potentiometers on the PIR sensor itself you could see that in the PIR brief section and there i a clear picture where one potentiometer is responsible for the sensitivity and the other one is for the time delay . you can adjust that in the sensor and the timer inside the sensor is from 0.3 seconds to about 5 minutes. or if you want to change in the software you could simply include a time delay of 5 minutes or more .for exampleif {state=0;if(pir_sensor == HIGH);{ state=1; digitalWrite(led,HIGH); delay(30000); state=0;}

great work

great work and thanks for posting it back as feedback

not really but it took 6-7 hours of work

thanks and yes it was done in the morning only XD

very soon a video about the UV meter will be released which basically does not need any kind of microcontroller part itself and talking about the DCduino is just a clone or copy of all the arduino board and in so many country the board itself is not available . thanks for your suggession . -kj electronics

The value of the pot can be 1k. And if you want to use the stereo then you can follow the upcoming tutorial .This arduino based uv Meter was just an introduction that how does the uv Meter works basically and if still you want to use the arduino then add shift register like74HC595 TO MULTIPLEX the output and you can use so many LEDs by using the multiplexing the arduino output is

nice work

the clear image of the audio javk is been shown in the the " part list " sectionit is a 3.5mm audio spliter type

Thanks for your great suggeasion

For sure

xD... Thanks

This is the very first part of the series on the music visualisation series and in a few weeks your thing will also be implemented and make sure you subscribe to my youtube channel to get most updates... Thanks you

For that you need to follow the step2 of the tutorial

thanks you

xD

xD

thanks
