Many Wish To Blink a Bulb With Arduino Like Blinking LED. Here is a Guide With Code & Circuit To Make Arduino Blink Bulb Without Relay. The reason you can not blink a bulb is very easy – Arduino can not supply enough juice exactly like not all motors can run with our basic guides on the web, we indicated the reason & solved problem in our Arduino Basic 3V Motor Control guide.
This is not a safe method. Do not run the bulb for more than 2-5 minutes for testing only. It may ultimately damage the I/O pins. Relay is required for technically right method.
Arduino Blink Torch Bulb : Watch Our Crap Quality Video
This crap quality video shows how our circuit and code to make Arduino Blink Torch Bulb :
bad quality will suck lesser bandwidth, you only need to see how it looks like in real.
Arduino Blink Torch Bulb : Things You Need and Must Know
This is actually not a great way for blinking a torch bulb, this is usually for who can never blink their bulbs after reading all guides on the web. We are providing 100% warranty that this guide will work. We used a DIY bulb holder, you can use a right bulb holder. We simply inserted pins in a tube which has a bore to rightly fit a torch bulb. This is a bulb intended to use with 2 dry cell batteries in torchlights.
You should have a bulb, an Arduino UNO board, few Jumper Wires, a breadboard, a multimeter, a breadboard power supply – specifically we need that YuRobot power supply.

Arduino Blink Torch Bulb : Code & Circuit Diagram
We have decorated with a Diode and 10K Ohm pull down resister for technically making it safer, in real test as you can see on the above video, we used no diode or resister.
Here is Circuit :
Here is code :

/* Bulb Fade Fade a Bulb on pin 9 using the analogWrite() function. Needs an External 3.3V Power towards the bulb, a diode & a 10K Ohm pull down resister. https://thecustomizewindows.com/ GNU GPL 3.0 Modified From Orginal Fade for LED */ int bulb = 9; // the pin that the Bulb is attached to int brightness = 0; // how bright the Bulb is int fadeAmount = 5; // how many points to fade the Bulb by void setup() { pinMode(bulb, OUTPUT); } void loop() { analogWrite(bulb, brightness); brightness = brightness + fadeAmount; if (brightness == 0 || brightness == 255) { fadeAmount = -fadeAmount ; } delay(90); } |
that closer to the last line delay(90) is a funny parameter to play with. You can make it 50, 60, 70, 80 to see the difference. Obviously you know how to create the circuit and upload the code. Do not connect the bulb first – instead add multimeter there to measure the voltage output. The output will be sinusoidal like. Also check for back flow electricity towards the Arduino board – measure with multimeter.
