@mubasher I am no expert but I haven't seen a capacitive sensor that is 4 feet long. It could be difficult to detect the difference in capacitance b...
@jonaskell You might have better luck if you reduce the serial speed to the monitor to 9600. That is the default speed for the Uno. It looks like th...
@christine86 I hope you worked out your problems in getting a PCB designed and manufactured. If I can help somehow let me know. My weather station...
I'm so glad!! Congratulations. Now that you got this far the rest should be all down hill. Unfortunately, my project has hit a wall. I'm working...
@christine86 Hmmmm, I thought you were using an Arduino Mega. I haven't used that MCU but I thought it had 15 analog to digital converters. If that ...
Christine, I had some time and set up a circuit for your battery charger in the SimulIDE software. I had one revelation, I don't know the voltage th...
OK, maybe we can kill two birds with one stone. I use this software (SimulIDE) not so much for schematics (It a little bit more like Fritz) but the re...
I believe I understood your the layout and the intent of your circuit. Unfortunately, I may not have been clear on my suggestion to fix your problem. ...
It looks like the MOSFET is in the wrong location. In the current configuration the FET will be turned on hard when the a PWM through a resistor charg...
No, if you look at how the current flows when each motor driver circuit is turned off there is no need. When the motor driver circuit is turned off cu...
@adrian If you have your circuit wired as the schematic indicates then diodes D2 - D5 are having no effect at all. You are showing the diodes as bei...
If the problem is truly static electricity then a very simple solution would be to connect a wire to your MCU ground circuit and let it hang down to t...
In general parallel is usually the best configuration. The reason is that in series the 12 volt converter will need to supply current for both your 12...
Nice solution! It gives me some ideas to mount an UV sensor I've been working with.
