This guide is not intended for the children as it involves household supply electricity. Household supply AC is overpowered enough to kill a human. We believe that controlling AC powered things like a bulb with Arduino often scary to many of the sane, careful hobbyists. However, with proper precautions they can keep you safe. Here is Description of Connections of Arduino 4 Channel Relay Module. … [Read more...]

With Arduino, We Can Have One Push Button Multiple Functions Like Single Press, Double Press, Long-Time Press. There is Nice Library For Faster Prototyping. Our readers already read different types of guides on push button usage, like Blink LED With Pushbutton Control, Blink LED Rate Depending On Push Button Press Duration, Flip-Flop Blinking LED With Push Button etc. Now our readers can … [Read more...]

We have lot of getting started guide with LDR. How To Turn On LED in Dark With LDR and Arduino is the basic behind all of them. We can perform the same work using transistor - Turn On LED On Dark With Transistor. As the value of LDR will be variable depending on batch, you need to run the basic Turn On LED in Dark guide to note the values on serial monitor in various lighting situations like … [Read more...]

The reason of publishing this article is to warn. It is common to join ideas for a new thing. It is more common to ask how to connect relay with 74HC595 shift register in Arduino circuit. It demands good knowledge with basic components to control AC things like multiple AC operated LED bulbs. It is not really joining our Arduino relay guide to blink single AC bulb and Arduino 74HC595 Shift … [Read more...]

In our previous article on 74HC595 Shift Register, we ave discussed the minimum basic theory. In this Article, We Will Discuss is How To Connect 74HC595 Shift Register With Arduino and LEDs. From the diagram on previous article, we can say that one side of the IC is for connecting with Arduino, another with things like LEDs. It is not very complex, although it appears to be … [Read more...]
