    Controlling RGB LED strip with MSP430?

    Honestly I have little to no idea what I'm doing I used these TIP51C for a lighting effect from an audio source. I had them laying around and just tried wiring them up the same way I found in that tutorial, I'm not using any resistors. My LED strip is less than 1M long, I've just cut off some to try out. I'll try and figure out what transistors would be best for this

    Controlling RGB LED strip with MSP430?

    I'm checking the TIP31C data sheet (https://www.fairchildsemi.com/datasheets/TI/TIP31A.pdf) and it shows Collector Current (DC) at 3V. But the Collector Current (Pulse) shows 5V. So I'm guessing that's the reason why it didn't work correct? This transistors requires 5V?

    Controlling RGB LED strip with MSP430?

    So it is possible to control RGB LED strips with the MSP430? Maybe someone could share the process involved? With the Arduino it looks really simple, would it be difficult to achieve the same thing on the MSP430?

    Controlling RGB LED strip with MSP430?

    I found some TIP31C's laying around. The board itself not 100% sure at the moment. I called my buddy who's into electronics and project such as this, he told me that the MSP430 only has 1 PWM output pin, so it seems this can be done easily only on the Arduino
  5. Hello, I was wondering, if it was possible to control a RGB LED strip using the MSP430? I found this tutorial for Arduino, I copied the circuit and the code, changing the pins to 14, 13 and 12, however it just fades the on board LED. https://learn.adafruit.com/rgb-led-strips/usage

    LEDs blink/fade with music?

    Does seedstudio sell the components I need? And what are those regulators?....

    LEDs blink/fade with music?

    Wow! I already gave up on this idea, but this is awesome!! Thank you!! What I wanted is more of an automated solution - not having to hook up a direct input into the board, with a mic it's just far better. So I think the mic part is easy - just hook it up and read the level. The LEDs are another story, I just .. don't know how to do it.. Edit: I'm thinking of also ordering this led strip http://www.seeedstudio.com/depot/blue-led-flexistrip-60-led1m-p-1120.html?cPath=81 do I need to order anything else in order to have all the parts needed to connect it to the MSP430?

    LEDs blink/fade with music?

    Well I guess I'm in to deep .. The stuff I find is incomprehensible to me .. Thanks to all of you anyway, need to learn more and come back to this project

    LEDs blink/fade with music?

    I'm sorry for all the newbie questions.. It's because I am one So I can just take apart a mic and "plug" in the wires to the headers and it will work??

    LEDs blink/fade with music?

    I've thought of making it software based, and sending the value of led brightness to the msp430 via serial, I guess that would be easy and doable for me. But then I thought I'd rather like a standalone system. So my first question would be, how do I add a microphone to the MSP430? Is it actually possible with Energia to use it, find some values and blink the onboard LED (first step) in regards to the music level or frequency or something I just haven't figured out how this should be done... Does Energia and/or the MSP430 have support for realtime audio analysis?
  11. Hi there, I've stumbled across a video ( ) and I really want to make something similar, but small scale for now with a handful of LEDs. I have no experience in electronics, but have played around with my MSP430 with a 16x2 LCD display. Right now I have like 10 or so LEDs, and I want to know how to connect them to the board?.. I've seen articles how to connect 3 or so LEDs so that they could be controlled individualy, but how do I connect them so I can control them as one? Do I need resistors or any other electronic component apart from a breadboard that has a 3.3v or 5v supply? In terms of connecting them, and having them work (electricaly) to me is unknown. I hope someone could help me out.. In terms of having the LEDs blink/fade with the music, how would you suggest doing that? Thanks.

    LiquidCrystal print string error

    Thanks! Changing to print solved it
  13. Hello there, I'm trying to output serial data received to the MSP430 and display it on the LCD. I do know that there is an example for it, but that way doesn't really work for me, the way I've planed my data to be received and outputed differs from the example. Here is what I'm tinkering with right now: #include <LiquidCrystal.h> LiquidCrystal lcd(7, 8, 9, 10, 11, 12); String Input; void setup() { lcd.begin(16, 2); Serial.begin(9600); } void loop() { while(Serial.available() > 0) { Input += (char)Serial.read(); } lcd.clear(); lcd.write(Input); delay(1000); } However it breaks on the lcd.write(Input); line, it won't accept my string! The full error: Is there any way I can write a string to the LCD?.. Thanks

    LED Display?

    Thanks for the links. So as I understand, my best option would be to use shift registers. Of course I have more questions about them, I hope someone here is patient enough to guide me through this I found a video showing that it is possible to successfully control a large-ish number of LEDs with the MSP430 My question is.. or are a) Am I limited to a set number of shift registers in terms of connecting them, or is it limited to the processing power the MSP430 can handle? Or both? Controlling. As I understand, I could connect the shift registers (don't get it if directly to the MSP430 or via another control interface). How would I be able to interface with specific shift registers, to power on/off the required LED(s)? c) Wiring. Kinda combines both questions. Is it possible to connect one shifter and then forward information to the next with on of the pins, or .. Just .. How to wire everything up? d) Does Energia support interfacing with registers? And is it "plug&play"?

    LED Display?

    My goal is to create something like this: Only without having such an input I'd do the actual reading of required text/animations from my PC via serial, or hard coded into the MSP430, but I believe there isn't enough RAM to handle that, so I guess serial communication is the best option. It's just that I want to figure out how to wire up and control those LEDs individually with the MSP430.
