.. same arrangement as before is used where a high signal is shown in red and a low signal is shown in green. I have allowed 10 seconds per step in the animation and slightly longer between repetitions so get your bearings during the first 10 ...
.. A), enforcing high linearity and accuracy. To calibrate this circuit apply 7 mV and select the 1.6M (nominal) value for 10 Hz out. Then apply 2.000 V and set the 10k trim for exactly 3 kHz output. Pertinent specifications include linearity ...
.. of analog amplification with opamps, I lowered the AD reference voltage to 1.6 V. This obtains 64 LSB counts for a 10 degrees celcius temperature range, the range used for 0 to 100 % fan speed control. (Click for download)
.. the tedious manual testing. I determined the 0ºC value of my thermistor ThermB to be 22500, with per-degree steps of 10.2 (or 102 with the 10x factor I needed to get around Arduino’s poor floating-point performance). Note: most ...
.. of which is controlled by timing capacitors C1 - C4 and the 10k potentiometer. The tolerance of the capacitors should be 10 % or better for stability. The squarewave is differentiated to produce a triangular wave, which in turn is shaped to ...
.. transimpedance amplifier at room temperature. It achieves this figure by taking an initial transimpedance gain of 10 MΩ and then attenuating by a factor of 10. The transistor section provides voltage gain and works on a 54 V ...
.. using a couple of transistors: because the leds are only on 1/60th of the time, we can use the transistors and the 10 ohm resistor to pack an extra punch. Just a note: as you can see, there's no battery backup or anything in the ...
.. monolithic Dot/Bar Display Driver IC made by National Semiconductor. It takes an analog voltage input on pin 5 then drives 10 LED’s providing a logarithmic 3dB/step analog display. When measuring power, a 3 dB increase means that the ...
