    voltage divider with load question and guess

    I do not know what is going on either Probably nothing. The circuit looks like nonsense to me. Wire your resistor any way you want, the circuit is still nonsense. This is way beyond hopeless - I give in

    voltage divider with load question and guess

    OK Whatever makes you happy ... If you decide to find out the truth - google "resistors in parallel", "Ohms law", "voltage divider" Not Googled those for myself, but I imagine that one or more may educate Buy yourself a solderless breadboard - a selection of resistors, a 9V battery and a...

    voltage divider with load question and guess

    Yes 1.8 Volts - but.... Just like all of your other posts, you are being hopelessly unclear. Between which resistors? There are 4 resistors in post #3, which voltage is of interest? Why are there arrows drawn on your diagram? - they seem to have no relevance Remove the meaningless arrows and...

    Small Project Advice

    If I were to make an electronic gadget for my wife as a gift, I would have divorce filed in the time it takes her to get to a solicitor. Flowers are simpler, cheaper and much better received. .... or is the intention to test your girlfriend's commitment to you?

    Temperature sensor with PIC18F45K80

    Use inbuilt 12-bit ADC first, then if stability is not good enough, use external one. Here is my suggestion of a way forward - feel free to ignore and do it any other way that you prefer 1) Start with your working UART code that you posted on Microchip forum. 2) Comment every line of your UART...

    How to test buzzer

    Just spotted a commenting error: TRISB = 0b0000001; // Buzzer connected to B0 Should be: TRISB = 0b0000001; // Button connected to B0 Code work just the same, but the comment is confusing

    How to test buzzer

    I now have a PIC18F45K80 and I am not afraid to use it :) Solution attached - based on OPs own code on AAC forum #define _XTAL_FREQ 8000000 #include <xc.h> // PIC18F45K80 Configuration Bit Settings // 'C' source line config statements // CONFIG1L #pragma config RETEN = OFF // VREG Sleep...

    ardino code for Two color LED to PIC18F45K80

    Hard to be sure, but from your earlier picture, it looks as though you are using a 1000 Ohm resistor and a 56 Ohm resistor 1000 Ohms = good 56 Ohms = burnt out LED

    BBC Micro:Bit?

    I think it is more a UK school thing than a hobby thing. Bought four microbit's and a whole load of accessories thinking it looked like a great product. Found it so uninspiring that I gave the whole lot away (to a neighbour's son). .... kept me amused for a week or two though...

    Quick tip on removing crimped cable?

    I usually use a flat-blade screwdriver under the bottom of the connector (closest to the switch) to gently lever the connector off. Take great care to lift the connector off evenly - a little at a time, making sure the connector lifts off vertically, not at an angle. Really cheap switches...

    Galaxy note 10.1 2014 battery problems

    Not seen any evidence to suggest that charger or cable could not be the problem. Not saying it is likely, just would like to see the simple suspects ruled out before going to the more difficult fixes. Are you confident that charger and cable are good?

    Will covering ring on male TRS jack with tape work?

    Agreed - balanced to balanced is the obvious professional solution. But I sense that you have missed my point. Half of balanced signal is not always the same as unbalanced at half amplitude. Picture an output that consists of transformer secondary that is isolated from shield. Connecting only...

    Will covering ring on male TRS jack with tape work?

    .... unless you own the (admittedly old) devices that I mentioned ... Did you read the discussions from my link? "Should work fine" is not the same as "does work fine" ... or maybe I mis-understand my own experiences ... Maybe the answer is to try open circuit ring, then if you hear...

    Will covering ring on male TRS jack with tape work?

    I have devices (Behringer 9024, DSP1400P) that require that the "ring" output (and inputs) be grounded for single ended output, otherwise massive noise and distortion are introduced. I sense that the solution balanced to single-ended depends on the devices to be connected. See discussion here...

    Spare time for tinkering

    Yes, bad choice of words - I maybe should have said life is ironic, rather than life is a bitch. Later in my career I would tend to avoid volunteering for overtime as it was about the only thing I had control over. Tough to turn down double/triple time money, but necessary for coping. Also took...

    Spare time for tinkering

    "Perhaps down the road in retirement I'll have more time for tinkering but perhaps not the motivation?" Retired - been there - done that. Life is a bitch. Sounds negative (or realistic), but I actually enjoy early retirement. Who cares if I acheive nothing, as long as I enjoy life, which I...
