Arduino Hello World Blink Code

This is a basic example how arduino works. In this arduino projects you’ll see how arduino control LED on for 1 second and off for 1 second repeatedly. Instruction; 1) Connect cathode lead of LED (shorter lead) to ground pin and anode lead of LED (longer lead) to pin 13. Upload this code to your arduino /* Blink Turns on an LED on for one second, then off for one second, repeatedly.This example  code is in  ...

Arduino led pendulum

Step 2: Putting up the wires Strip both ends of wires -insert one end of each wire into sockets numbered -Gnd(black wire in my case)-this will be the common ground connection - 13  (green wire in my case) - 12  (yellow wire in my case) - ~11  (orange wire in my case) - ~10  (red wire in my case) - 9    (brown wire in my case) - 8    (brown wire in my case) Step 3: Hooking up wires to the breadboard - hook u ...

like timer includes Sub-1V 555- LED driver and charger

Semtech has introduced an analogue timer chip that runs from 0.9V, but can drive LEDs at over 3V. Called SX8122, to the timer it adds: a simple battery charger, a boost converter, and a power-down controller. “It is designed for on/off button debouncing, delayed start-up timing, programmable sequencing and timing-out in toys, remote control, electric toothbrushes, buzzers, and LED pointers,” said Semtech.

High LEDs brightness get power drive

Description The LT®3743 is a fixed frequency synchronous step-down DC/DC controller designed to drive high current LEDs. The average current mode controller will maintain inductor current regulation over a wide output voltage range of 0V to (VIN – 2V). LED dimming is achieved through analog dimming on the CTRL_L, CTRL_H and CTRL_T pins and with PWM dimming on the PWM and CTRL_SEL pins. Through the use of ex ...

Make your own Custom Electronic Widgets, like my Arduino LED Day/Night Widget

This is just a brief run down on how easy it has become to make your own circuits complete with your own PCB's.  Have you ever wanted to make something custom that suits your needs? Of course you have!! For me it really started when I built my first day/night light. I used a light dependant resistor to determine if it was dark and if it was to then turn on an LED light. I then went on to add a movement sens ...

Pressure Activated Light-Up Umbrella using an Arduino

Once upon a time, 2 girls greatly enjoyed walking in the rain with umbrellas. They decided the enjoyment of this experience could be maximized by building their own pressure-activated web of LEDs to install under their umbrella. Thus, with the help of an Arduino, some 4051 multiplexers, a lot of wire and a lot of solder, they set off on their path to success. Step 1: Materials List Just based on size, we de ...

Flicker up to 6 LEDs with Arduino

Hi there. Christmas is coming closer, and I was wondering if I could put some candles in my room to get in the "christmas mood". But after a friends house burned down of christmas tree candles, I don't want to burn real candles into my room. So why don't let the Arduino light for you?! This Instructable will show you, how to flicker up to 6 LEDs using an Arduino Microcontroller. For more information about A ...
