MEMS Accelerometer with LED bar display. Car Test 1

[MrRushabhT]

hey...awesome video...I am actually working on something similar for my final year project..I need to demonstrate the intensities of the centrifugal forces acting on my Adxl335 whilst cornering...I was wondering whether you can email me your source code for doing this? I'm a beginner and have some ideas but a little help would be nice...I was planning on using an avr (Atmega32 or Atmega88)....cheers...

@MrRushabhT Hi, I used completely analog circuitry with LM3914, MMA6280 dual axis accelerometer and some resistors capacitors in these project, I can't find schematic and PCB design anymore. If you would implement it on micro it should be fairly simple, use ADC inputs to read output from ADXL335 and output this on ports that drive some LED-s, you can use scanning output technique to light LED-s if you need more than 29 LED-s connected.

I want one... :(

@qazxsw21000 I am thinking in making this a commercial product and sell it on my web page. I will do that if I get enough requests.

@cerapcic did you get enough requests?

@Thrashaero Thanks for interest, yes i got enough requests, now I am developing digital version with lcd screen and optional sensor inputs for boost pressure, temperature, speed, RPM...
