Re: LED in series

LED connection with power depends upon your requirements if you want to light up for some more time and you have current then use in series but if your have limited voltage then use parallel method also you need precise value of resistors for any type of connection.

Re: can anyone give me some advice on choosing resistors

Resistor are not a a dress that you can choose for your design so that your products looks nice. It is vary with lots of factors like current, voltage, frequency etc. So, first understand what is resistor and how to calculate the value in circuit then you will know how to choose the resistor.

Re: Optocoupler Circuit Overheating

Only major things to heating circuit is due to uncontrollable flow of current from source. Try to reduce the high current flow from source or use the heat sink for IC like 555 , voltage regulator IC.

Re: Ardumoto Overheats

Heating is because of high current. Please see the datasheet of L298 once to know how much current it can handle and also see the current consumes by the motor during operation. As much as I know current is only factor here which making driver hot. To reduce for now you can use some current control ...

Re: Attiny85 pin 1

In order to use pin PB5, which is the reset pin, you need to program it with specific fuse settings. And because you cannot reset it anymore you need a special high voltage programmer. The ICSP method of programming won't work. And the regular arduino bootloader neither, for sure. Here is a tutoria...

Re: Why is Attiny85 so popular?

ATtiny85 is very useful micro-controller for real projects and if compact design then it has more importance. Try once and and feel the simplicity for complex project :)

Re: Detecting Lightning with an Arduino

This is very interesting topic . I also used to get detection using some IR sensors but it works only at midnight after I was in dream :( . But later I find this https://create.arduino.cc/projecthub/runtimeprojects/a-lightning-detector-for-arduino-9f679c which is quite interesting to work and learn ...

Re: 3/4 HP 12VDC motor Controller

Hi there, have you checked with amazon, there you can find " Motors Electric Pump Fan Speed Stepless Control Module with Reverse Polarity Protection High-Current Protection". This may help you and any kind of motors you want to run in future.

Re: Need help for my first project

You can use simply LDR or IR sensor in main sensor and A and B can be white paper and black paper . You need one interface between computer and main sensor that can be simple controller Arduino. Then when white paper is near to main sensor arduino will provide either 1 or 0 (which you can set by pro...
