fuel level
Hi It is the simplest digital filter you can imagine :) Lets assume you have 12 samples of measurment. Now you do an avarage function for example: ((s1+s2+s3+s4)/4 + (s5+s6+s7+s8...

Comparator Question?
Hi Theush is advising you really good ! Just do ADC conversion and then write your own comparator. i.e.: adc=ADC_read(0); if (adc > value1) { if (adc value2) { //do...

cheap way to calibrate the int. RC osc.
Hmm Yeah it can work but I still don`t like a design. http://en.wikipedia.org/wiki/Image:Rs232_oscilloscope_trace.jpg "1" -3 to -15 [V] "0" +3 to +15 [V] In this design you reach...

cheap way to calibrate the int. RC osc.
Strange idea for me ;) As far as I am concern after riding it, you connect your uC straight to comx via RS232. Where is voltage converter MAX232 for example ??? Wouldn`t be easier...

Best educational AVR kit?
In my opinion the best option is to start the easiest way you can. I started with primitive programmer (few wires connected to paraller port) and breadboard. This costed me really...
