Review – Texas Instruments TLC5940 16-channel LED driver IC

The first chapter is here, the complete series is detailed here. Introduction Today we are going to examine the Texas Instruments TLC5940 16-channel LED driver IC. Our reason for doing this is to demonstrate another, easier way of driving many LEDs – and also servos. First up, here is a few examples of the TLC5940 The TLC5940 is available in the DIP version above, and also surface-mount. During this tutorial we’ll explain how to control one or more TLC5940 ICs with LEDs and also look at controlling servos. Build a TLC5940 demonstration circuit The following circuit is the minimum required to control sixteen LEDs from your Arduino or compatible. An Arduino Uno or compatible board16 normal, everyday LEDs that can have a forward current of up to 20 mAa 2 kΩ resistor (give or take 10%)a 0.1uF ceramic and a 4.7uF electrolytic capacitor R = 39.06 / Imax R = 39.06 / 0.02 = 1803 Ohms.

A Multi-Protocol Infrared Remote Library for the Arduino

Do you want to use your Arduino to control your stereo or other devices? This IR remote library lets you both send and receive IR remote codes in multiple protocols. It supports NEC, Sony SIRC, Philips RC5, Philips RC6, and raw protocols. If you want additional protocols, they are straightforward to add. The library can even be used to record codes from your remote and re-transmit them, as a minimal universal remote. To use the library, download from github and follow the installation instructions in the readme. How to send This infrared remote library consists of two parts: IRsend transmits IR remote packets, while IRrecv receives and decodes an IR message. #include <IRremote.h> IRsend irsend; void setup() { Serial.begin(9600); } void loop() { if ( !

This sketch sends a Sony TV power on/off code whenever a character is sent to the serial port, allowing the Arduino to turn the TV on or off. How to receive Hardware setup. Kalshagar - Arduino and a Nintendo DS touch screen. Quite easy to do, with inexpensive components (Touch screen is 10$, break board connector 4$ and just buy it, don't be a hero), but with one or two caveats.

kalshagar - Arduino and a Nintendo DS touch screen

Sample, wiring and code here under. Everything is basically an application of Elm-chan's very good tutorial (but not in Japanese). Caveats and what you should know Don't buy the connector alone, just buy the breakboard, it's not posible to solder with a "usual" iron. And buy 2, because it's quite fragile and I killed 2 (hopefully I had spare parts!) Pictures Too many people use this, too few put a diagram. With the 10 kOhm resistors, nice reading, no recalibration : raw results drawn on a 800x800 picture. Arduino 2009 + 4x 10 kOhm + Connector + DS touch screen.

Learning Examples | Foundations | Hacking | Links Started by Carlyn Maw and Tom Igoe Nov, 06 Shifting Out & the 595 chip At sometime or another you may run out of pins on your Arduino board and need to extend it with shift registers.


This example is based on the 74HC595. The datasheet refers to the 74HC595 as an "8-bit serial-in, serial or parallel-out shift register with output latches; 3-state. " How this all works is through something called "synchronous serial communication," i.e. you can pulse one pin up and down thereby communicating a data byte to the register bit by bit. The "serial output" part of this component comes from its extra pin which can pass the serial information received from the microcontroller out again unchanged. "3 states" refers to the fact that you can set the output pins as either high, low or "high impedance. " Projects. DSO Nano v2 Pocket Oscilloscope.

Voici maintenant quelques temps que je possède ma carte Arduino et je commence a vouloir expérimenter d'autres choses que faire clignoter une led ou lire des valeurs analogiques sur une liaison série.

Real Time Clock: DS1307

C'est pour ça que j'ai commandé le DS1307 qui est une Horloge temps réel commandé par I2C. C'est d'ailleurs un très bon moyen pour moi d'apprendre à utiliser le bus I2C que je connais pas encore. Je vais donc rassembler ici, toutes les infos et démarches faites pour faire fonctionner ce fameux composant.
