Connect pin #28 of the expander to +ve end of an LED then to a ~1kohm resistor to GND (MCP_LED1) or wire directly to 5V. I must have been thinking of open drain controls - you don't need the resistor. Connect pin #26 of the expander to +ve end of an LED then to a ~1k...
To pick a few figures: a digital output, say 3V, with a series 100ohm resistor, 1ns risetime one side of that digital output is connected to an inductor to ground. That inductor represents the inductance of the ic's ground lead, 1nH/mm so say 5nH that resistor is connected to a ...
Suppose you have three resistor each of value (30 Omega).List all the different resistances you can obtian using them.
Change the RCS resistor from 50mOhm to 125mOhm (0.125 Ohm) to change the charging current to 300mA. Remember, these bulb have to be supplied 16V (min) so the filament starts glowing, but once the arc is established, current has to be limited to 300mA (settling at around 10V) ...
simple. In my youth, I briefly worked in the calibration lab of a large aerospace company and asked the supervisor the same question. He said “You may think they’re alright, but they could have been dropped or zapped out on the [production] line. You never know until you check ‘em...
The basic LDR (Light Dependent Resistor) works in the Lightspeed Attenuator by mimicking a 10k ohm series shunt logarithmic potentiometer. In the Lightspeed Attenuator, the signal goes throughnothing but one single soldered resistor!Not one sound robbing, light contact metal wiper on a resistive tra...
while i cant change anything in the library file generated and getting this error, can i add a dummy resistor (e.g. microohm range) ? it's will not impact the original behavior ? because i have to keep it. this what i have done ...
0, brown to 1, red to 2, and orange to 3. simple numbers appear on the initial two lines, and the multiplier appears on the third. as a result, a resistor having three bands—brown, red, and orange—would have a resistance of 12,000Ω. as a result, the resistor has a 12,000...
What capacitance do you need to produce a resonant frequency of 1.00 GHz, when using an 5.50 nH inductor? What capacitance do you need to produce a resonant frequency of 1.00 GHz, when using an 8.00 nH inductor? What capacitor in series with a 100-ohm res...
Security System plans have always been expensive. For example, a Smart Security System can cost up to USD 1500 just for installation, and on top of that, you still have to pay monthly fees! So, a simple solution is to build your own Smart Security System using the Raspberry Pi 4. ...
