    ADC only Capacitive Touch

    Microchip recently put out a PDF describing how to use only ADC for Capacitive Touch Sensing. It works on the voltage divider principle. I stumbled upon Cap Touch while looking for something else and became very interested in it. My ultimate goal is to use thumb tacks stuck in a wooden...

    Digital Gages for Tractor

    Thanks for the help jumper2high. That looks like a voltage divider. I'm still going to have to think about it but I think I can get it now.

    Digital Gages for Tractor

    I glad I passed the test on how to read voltage on a pot but I can't relate this to a one lead sensor. If someone could give me a simple schematic on how to connect this sensor to a pic I would appreciate it.

    Digital Gages for Tractor

    I have used a pot for adc pwm on the pic to control the speed on a small DC motor. I hooked one side to +5v the other side to 0v and hooked the middle to a pic pin. I suppose if I was trying to read the voltage with a voltmeter I would hook the positive lead to the to the middle lead of the...

    Digital Gages for Tractor

    I'm far from being an expert in electronics but I do know about Ohm's law.

    Digital Gages for Tractor

    There is no output voltage from the sensor. It is connected through the metal of the tractor to the negative side of the battery. The analog gage has a positive connection to the battery on one side and is connected to the negative side of the battery through the sensor. There is only one...

    Digital Gages for Tractor

    I am toying around with building pic based digital gages for my tractor. The gages would be fuel, temperature, oil pressure and battery. I need some help understanding how a couple of these could be done. The fuel is very straight forward. It has a variable resistor/rheostat operated by a...

    Code problems with 16F88

    VSMVDD, I meant to ask you in last post and forgot. What is proteus? It sounds like it might be a simulator.

    Code problems with 16F88

    VSMVDD, Apparently I didn't notice your reply earlier. The first config statement does contain a clock setting I think it is INTOS_IO. The clock is further configured in the OSCCON register. It's configured for 4 mhz. I have cleaned the code up and I will try to attsach it as a zipped .asm...

    Code problems with 16F88

    Thanks for the reply Buriedcode. The diagram, I am learning is weird, I don't know much about electronics and really didn't know how to connect the caps. I justed connected one the way you suggested with still no results. I really don't think the power supply is the problem because as I...

    Code problems with 16F88

    Thanks for the help. I installed caps as shown in the sketch below. I don't know if this is the proper installation or not. They had no effect on my problem.

    Code problems with 16F88

    I don't have any caps nor crystal. I'm using internal clock on the PIC. All I have on the breadboard is a voltage regulator, the PIC and a LCD.

    Code problems with 16F88

    is lo or hi better porta 16f88 Can someone tell me why the attached code won't run on a 16f88 PIC. This is a simple elapsed time timer running on a timer0 interrupt and displaying the time on a 2 X 16 LCD. I downloaded the code from several places and put it together. With the minor...
