I've attempted to contact someone at Arduino for you. Sorry to hear about your problems. We at the forum can't do much more than pass it on to someone who may be able to help. In this video I will show you a better joystick. This joystick was more expensive, but it is more precise, has better feeling and response, and has larger range of motion. I show you some general ideas about how to understand the potentiometers in these specific circuits/devices.

This is a non-contact water / liquid level sensor for Arduino.It utilizes advanced signal processing technology by using a powerful chip (XKC-Y25-T12V) with high-speed operation capacity to achieve non-contact liquid level detection. We provide you customized training packages in both offline and online mode that suits your needs. Reach out to us for getting detailed information about training curriculum and in case you need our services for development of your products involving software and/or hardware then please feel free to. This FREE arduino nano driver provides 12 dry contact inputs to your Control4 system through serial based communication. This is useful for connecting input based devices such as doorbells, motion sensors, door/window contacts, garage/gate sensors and more to Control4.
When you are using DS1302, DS1307 or DS3231 RTC in your real time clock project, You may have observed it’s library works on 24 hours format clock. If you are like me who don’t like to see clock in 24 hour format, this tutorial is for you. we will learn how to set 12 hour clock in RTC (Real Time Clock) using DS1302 with TFT Display. It is simple to convert from 24 hour format to 12 hour format clock by using any of DS1302, DS1307 or DS3231 RTC. In short we are subtracting 12 hours from 24 hours. So let’s get started.
Components Required:
Libraries Required:
1. DS1302 Library:
Download library for Real Time Clock library from Rinky-Dink Electronics OR you can download it from here because library may change by the time or it may not work.
Download Real time clock library DS1302.zip
2. MCU Friend TFT Display Library:
- mcufriend_kbv
- Adafruit_GFX
- Dependencies Libraries (Touchscreen etc)
Arduino Contact Switch
Open Arduino IDE. Go to Sketches > include library > Manage Libraries > Type library name > install

Circuit for 12 Hour Format Real Time Clock with TFT Display:
Set The Current Time:
Set the current time in 24hr format, don’t worry it won’t show you time in 24 hour format. Because of our code it will take automatically time according to AM/PM. After setting the time, upload the code.
Now, time is stored in DS1302. You will need to comment out the following lines and again upload the code.
Note: If you don’t comment out and upload the code. It will cause Arduino to start time from where it is been set. Not from current time.
Code For Arduino 12 Hour Clock in RTC:
Code Explanation:
This line will update screen portion, where second is appeared.
Update whole TFT screen every one minute.
If hour is greater than 12 hours. It will minus 12 hours from it. At the same time make activate equal to 1.
If activate is equal to 1 it will show time as PM else AM.
I have added this code for date, hours, minutes & seconds. This code will make sure, time should be in double digit, not single digit.
