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...]

We are been in the necessity to 74HC595 shift register. We also call it 595 chip. With Shift Register, You Can Use One Arduino Pin To Blink Multiple LED. Here is 74HC595 Shift Register Theory For Arduino Tutorials. Earlier, we talked about how to increase pin of Arduino, how to connect multiple LEDs with one Arduino pin, multiplexing and charplexing etc. Neither all understands too complex matters … [Read more...]

We Can Use millis() To Perform Many Things Without Using the delay() Function. We can code to read a push button to determine the rate at which the LED should blink. In that system, if we hold the push button down for x milliseconds, the LED will blink on and off every x milliseconds. Here is Arduino Blink LED Rate Depending On Push Button Press Duration Guide With Circuit and Code. For our … [Read more...]

Just Like We Can Vary The Rate of Blink With Heart Rate Sensor, We Can Control The Rate of Blink of LED Depending Upon How Much The Light is Present. That is Exactly What Arduino LED Blink Rate Control With LDR Will Show With Sample Code. We we connect LDR with Arduino, on Arduino IDE's serial monitor we can get a value on dark and highest light. That exactly the thing we use for more easy project … [Read more...]

In earlier article, we discussed the basics around NeoPixel LED. We also warned about higher current consumption NeoPixel strips used for decoration. Connecting Single NeoPixel to Arduino is most simple. Thinking specially about the children, we feel that single NeoPixel is completely safe, affordable and easy for them. Here is Connection and Sketch For Arduino UNO Single NeoPixel Rainbow Blink. … [Read more...]

Multi-color LEDs becoming common in decoration. Questions with NeoPixel LED also becoming common. What is NeoPixel LED? NeoPixel LEDs are digital LEDs which has 3 LED in each package for RGB and own IC. They are digitally addressable LEDs and gives us the control on large numbers of LEDs using digital signals. Can We Interface Consumer Grade Multi Color LED Strip Sold For Home, Christmas, Diwali … [Read more...]

Connecting Multiple LEDs in Series Can Create Nice Lighting Effects. Most of the consumer grade Christmas light, Diwali light etc uses just some common IC and transistors. Here is How to Connect Multiple LEDs With One Arduino Pin. In respect to one Pin, result is like as if of Series Connection in ordinary electrical circuits. Current in Arduino UNO single digital pin will provide 40mA and can … [Read more...]
