bigone5500 submitted a new Showcase Item: Capacitance LCD Readout Read more about this showcase item here...
I have been doing some studying and think I have figured out how to get this thing to do what I want. I will however, have to wait for my new lcd to arrive. You must not apply 12 volts to a 1602 lcd...EVER!
I worked on my sketch a little today and think it looks good. However, I don't have a 1602 lcd to test this out. I left the serial output in the sketch to be able to view it on the serial monitor. I would like someone to download this sketch and try it out if you have time. I would appreciate it. But first, please review it and let me know if there is anything that can be done differently or if anything is wrong with it. I will be doing a Fritzing project to go along with this soon.
I have updated the Arduino sketch. There were some errors I found. The sketch now compiles with no errors.
*UPDATE* ...the Chinese Maritime Association is on the way with my new LCD. It should arrive sometime between now and then.
I have an I2C version of this display and am working on getting the code to work with it. I should have it working soon.
Here's the I2C version of the sketch. I have commented out the parts that relate to the serial LCD. I'm sure that if using a parallel display, the sketch would work fine. Just comment out the I2C parts and uncomment the serial LCD. Serial monitor also works along with LCD output. I got errors compiling while they were both listed. I had tried to use my Mega but the readings were way off. I installed a 1uF cap and got 4uF. A 22uF read at 75uF. It reads pretty close on my UNO. However, I am not sure I can fully trust the readings. Any ideas???
