LED Chaser using Arduino
This is a LED Chaser, with the simplest code. Here you vary the speed of chasing LEDs by potentiometer which is as analog input to arduino.You can have different LED glowing arrangements, like Knight Rider is kinda famous, you can make it by simply putting the same loop but with descending outputs 😉 try it.…
Flashing LED using 555 Timer
Demonstration The circuit is designed to use very little current to prolong battery life so that it can be left on permanently. A superbright’ red LED is used because this provides a bright flash with a low current. If you want to use 4.5V supply by connecting 3 Alkaline cells or any other source, change…
Flashing Rail road Lights
Demonstration This project flashes two LEDs alternatively with equal intervals of time so they act like a Model Railroad lights :).In future when you will be designing any Robot, you can use this circuit in order to decorate it 😉 Parts Required & Circuit Diagram: Bread Board Arrangement:
LED Dimmer
Demonstration The circuit which i found initially had 50k potentiometer, but the one i have used is 10k and it worked fine with that. The code for the 100nF capacitor is “104” so any capacitor which has this code is to be used in this circuit. You must use a Bright LED for this, buy the one of a…
Fading LED with 555 Timer
Phewwww Finally it worked!! “Successs!!!” (Dexter’s style) I used arduino and it was too easy to just control the Brightness of LED by simply putting in numbers in code lolo I started looking on google a circuit to make LED fade up/down using 555 timer, i found lots of circuits but LED used to fade…
Servo Tester using 555 Timer
Demonstration This circuit is a servo tester, probably when you purchase a servo for your robot or model the first thing is you want to test whether it works or not. There are already commercial small circuits available for this in which is like a small box where you put in battery and hook your…
Light Sensor using Arduino
Demonstration Connect one pin of LDR to 5v and another pin to A0 input.This is a Light sensor using LDR and Arduino, you can make it either Shadow detector or light detector by simply changing the code given below. Connect one pin of 10k resistor to GND and another pin to A0 input The code below makes…
3D Printing Technologies | Types of 3D Printing
All 3D printing technologies create three-dimensional physical objects layer by layer from digital designs from many sorts of materials like plastic, metal, resin, concrete and Human Tissue. Additive manufacturing (AM) is the very appropriate name for describing 3D printing technologies. Check out On demand 3D Printing Service in Dubai UAE 3D Printing or AM describes a…
