So I got everything nailed down, Seperated wires to their specific catagorys. Illumination, Fuses, AC Pressure Switch, and the Sunlight and Photo Senser. The Wires Im suspicious about are these wires below. I had the plug ins from a cluster to verify if the claimed wiring on the diagram is accurate. These T3. 2s came out of a 2. VR6 Jetta, but the wiring is still similar from what Ive been told by the Volkswagen Mechanics. The diagram shows 4 wires connecting to the certain pins in the T3. I only have 3 of the 4. What does the T1. T3. 2a1. 1 connection supposed to control What is the purpose of connecting those wires to the clusters harnessThese wires are my suspicions, please help me in figuring out, for positivity.

Feb 2. 01. 1 Arduino Musical Lighting System V1 and V2Introduction. This project was motivated by a desire. The common dorm room usually comes. My room in Next House was no exception. Yet the idea of buying a little table lamp was unappealing. Earlier on in the semester, I had acquired a set of three 2. W Halogen lamps and they added much warmth and comfort everybody loves. Halogens. Still I wanted a bit more dynamism and colour not to only install additional lights, but also to bring a bit more flavour and piazza to my room. Afterall, I was. in a tech school. In the early spring of 2. Impulse, which was a party at the basement. The cool thing about the party was the custom lights a 2. It was extremely successful, and made me recall the amazing dancing lights I saw at another dorm room a few months back TEP for the record. So I decided to build my own musical lighting. This page documents the journey I went through to make this. Update End 2. 01. Just. less than two months after I conceived of the idea, the. The result is showcased. For more information, refer to the project log and notes below. Update Start 2. 01. It has been six years since I started this project and its time for an update The update includes several improvements including a revised and tided. LED colours, improved driving. Arduino Uno but keeping the. Scroll down for more. Design Considerations. The goals of this project were straightforward. I decided to adopt the Arduino development platform using the Arduino UNO board running a ATMega. Microprocessor. This was chosen due to its low cost, ease of use, fantastic documentation and versatility. This was also my first project with the Arduino platform so it. I also decided to try out first hand the new high powered LEDs which. Chinese distributers like Deal. Extreme. The principle of the music visualizer is simple. MP3 player into the. The microcontroller reads out the waveform and performs a frequency decomposition into several different frequency bands. The microcontroller then takes the amplitude of each frequency band and uses it to modulate the brightness of one of several ultra bright LEDs using Pulse Width Modulation. PWM. Since the microcontroller cannot output more than. A safely, MOSFETs are used to switch the high powered LEDs, and eventually, Halogen. Finally, I know I can purchase a similar. These are the goals of the project To design and construct a simple and portable lighting system with ultra bright LEDs. Allow modular implementation for extension to other lighting systems, e. Halogen lamps. 1. V or 2. 40. V bulbs. Learn to use the AVR microcontroller system via. Arduino. Implement a basic but effective lighting algorithm for first version of system. Incorporate more complex and fancy lighting algorithms for subsequent versions. With these few ideas in mind, the project beginsProject Log Feb 2. Arduino Uno arrived today. I bought an Arduino. Uno on Amazon. com for 2. I had a 2. 0 discount voucher which. I spent 1. 0 buying. Unfortunately I cant work on anything else now. Im still awaiting some other components. Spent some time. reading up about the basic functionality of microcontrollers. This. is after all my first real microcontroller project. Mar 2. After some initial research, it was apparent that standard implementations of Fast Fourier transforms run. Atmega. 32. 8. However, I discovered that there exists a 7 band graphic. IC which will be able to filter out the 7 frequency bands of my input audio, and it all comes nicely in a small 8 pin IC This is the MSGEQ7 graphic. I couldnt find a cheaper and easier place to get the MSGEQ7 graphic. I ordered some from Sparkfun electronics. The MSGEQ7. was 4. I havent decided which LEDs to buy yet, but it seems that the LEDs I am currently interested in. Deal. Extreme run at about 3. V varies with colour and have conflicting reports of it being driven from 3. A, at which they run quite hot. Regardless. the microcontroller output pins can supply no greater than 4. A. In order to switch the bright LEDs, one could use a transistor like the TIP1. TIP1. 20 darlington. I decided to go for a standard logic level N Channel. RFP3. 0N0. 6LE. It is rated for 6. V at 3. 0A and is an overkill for the project. If all goes well, I should be getting the components in about 1 or 2 weeks. Next up on order are the powerful 1 3. W LEDs, which will probably be from Deal. Extreme. 4th Mar 2. After sorting out the initial plans for how I would want to make the lights, I ordered some powerful LEDs from Dealextreme. I do not know the exact power rating. LEDs are but they have been claimed to be driven u to 7. A, which works out to be over 2. W input per LED. The plan is to have 6 powerful LEDs of different. MSGEQ7. These will be White, Red, Yellow white with gel, Green, Blue, Purple. White with Gel. I also purchased a few other spare components. These. components are 3. W Multicolor LED 4. Red CREE LED Emitter 1. Blue CREE LED Emitter 1. Green CREE LED Emitter 1. White CREE P4 LED Emitter 1. UV LEDs x. 20 2. Mar 2. Today I finally got started working on the project since I had received some of the components and could begin. I got a breadboard and started laying out the circuit. The. initial plan is to use the MSGEQ7 spectrum analyzer which is a 7 band filter and will output the amplitudes of each frequency band based on a driver frequency. Setting up the circuit was relatively straightforward. One channel. out of two from the Stereo input was used and the signal was sent to the graphic. After a few quick initial tests, I got the circuit. The MSGEQ7 outputs the amplitude of the frequency. ADC. Right now Im just dividing by 4 fast binary operation and sending it as a 8 bit value to the Atmegas Pulse Width Modulation output. Since the ATmega. PWM outputs, I connected. LEDs to the output and ignored the last highest frequency band. First. Result the circuit worksThe most. LEDs is are not contrasty enough. This is expected since the. More work will be done soon to fix this. School beckons. 2. Mar 2. 01. 1 A quick improvement. I didnt have much time so I just did some small tweaks to the. This has mostly got to do with the contrast curve. After some experimenting and looking at various graphs, Ive settled on. SinSin4 curve, but will probably optimize it further for better. I also found a white LED and used it for the bass. I recorded a short video of it in action. Now all I need is to await the bright LEDs to connected up via the. MOSFETs. 2. 9th Mar 1st Apr 2. Have received the bright LEDs from dealextreme This week at least till Wednesday is a bit busy so I hope to begin at least wiring up the LEDs and the. MOSFETs within the week. Update 1st Apr Its April Fools today However, not much stuff was going on in school. I headed over the MITERs, a little workshop in my school, and soldered the LEDs to wires for easy connection. I also did some tests on how uch current I should be sending into the LEDs. I do not know exactly what the part numbers for the LEDs are except that they are CREE LEDs. The specifications actually seem to read that they are capable of 7. A input each at varying voltages, but Ive heard reports that they run really hot at that current, and most people are fine with 3. A. So I plan to run them at 3.
