- Capacitive touch buttons not seeing touch - All About Circuits
This can be do to a lot of factors: your fingers are dirty wet in scars The capacitance of the object to touch with (fingers) is not high enough As far as I guess, these displays check the increase of capacitance between the finger and the display on touch, but normally it is recommended to use a pen or a resistive display Try to search for a way to calibrate the display (how much
- Capacitive touch trigger as an isolated system - All About Circuits
I need a way to trigger a capacitive touch screen device (like a tablet) using an isolated system without touching it For example a kid places a small gadget on a tablet screen and the gadget will trigger a capacitive touch on the tablet without requiring anyone to be holding the gadget or the
- What is the capacitive load? - All About Circuits
What is the capacitive load and how can capacitive load be simulated? I want to monitor the current and voltages in the simulation by powering a capacitive load from the battery, but I am not sure whether I am doing this correctly
- Best Way to Activate a Touch Switch Without Touching It
Hello there, I'd like to activate a touch switch electronically It's a capacitive type switch There can be no wires connected to the capacitive switch, it must come from something completely isolated from the touch switch circuit I know I can use a piece of metal and a linear actuator
- Why capacitive reactance reduces inductive reactance (by intuition . . .
I understand why capacitive reactance reduces inductive reactance mathematically, having a result of zero at resonant frequency But how to physically explain the flow of electrons in a series LC circuit, where the coil lags the flow of current (electrons) relative to the applied voltage
- Buffer design for driving capacitive loads. | All About Circuits
Hello, How to calculate the number of (CMOS inverter) buffer stages to drive capacitive load? In my case, I am driving a 1nF capacitive load with CMOS (inverter) buffer with the digital signal having an amplitude of 0-5V, and 1Mhz frequency Thanks
- Choosing between capacative and FSR sensor? | All About Circuits
Also, the capacitive sensors are very sensitive to environmental factors — humidity in coastal water climates can affect sensing output, so they may not be robust enough Does anyone have experience with either of these sensing techniques and could provide a recommendation for this application? Thanks a lot!!!
- Capacitive Voltage Divider - Downsides? - All About Circuits
Capacitive voltage dividers are really only usable for AC circuits Capacitors block DC, and pass the effects of AC However, attempting to use capacitors in the place of transformers to provide isolation from the mains power is extremely dangerous, as capacitors can (and often do) fail You must use a transformer to safely isolate yourself from the mains power Discussion of hazardous
