Learn Robotics with Arduino - Liquid Crystal Display
Slide 1: Learn Robotics with Arduino Liquid Crystal Display. This course will teach the detail steps how to learn Robotics with Arduino by hands-on training and practice using the example projects of liquid crystal display.
Slide2: Based on the available parts of my starter kit, after reviewing Arduino project book, and some online Arduino project e-books, I decided to work Liquid Crystal project as my first real project using the starter kit. From Arduino Documentation website, you can search and find all related information about your project.
Slide 3: Circuit diagram of Crystal Ball project which can work for all sketches in Liquid Crystal example library. I replaced the tilt switch by the push down button switch because the tilt switch is not included in my starter kit if I am not wrong.
Slide 4: Some explanations for building the circuit.
Slide 5: The parts list; Beside of the liquid crystal displace, breadboard, Arduino Uno R3, additionally, we need 2 resisters (220Ω and 10kΩ), one potentiometer, and one tilt switch as the digital input for crystal ball project. This switch is not needed for verifying all sketches in liquid crystal example.
Slide 6: My starter kit came with two types of CONN HEADERs R/A and VERT. R/A type allows the liquid crystal displace stands on the breadboard, I chose it. But later I found all the characters on the display are upside down. I am guessing in the sketch I should can correct it but I leave this question to our readers. I reviewed some old videos about this project and understand we may have various issues during building the circuit. First we need to solder the conn heads on the display as shown on the upper right conner. Second, there are a lot of wire connections on breadboard. Need to use the multimeter to check the connection and voltage. Please check carefully before connecting the USB cable to a computer that powers on the Arduino board.
Slide 7: When the circuit is connected to computer through USB, the liquid crystal display should be lighted up immediately. If not, go back to check the circuit. This is the front view. You may see the small push button switch which is used in crystal ball project to make a guess by pushing the switch as digital input.
Slide 8: This is the back view. It may be challenging for a beginner. Keep patience and confidence. You can do it.
Slide 9: The following three slides are for backup in case you want to learn more about the crystal ball project and its circuit. This is backup slide1.
Slide 10: This is backup slide2.
Slide 11: This is backup slide3.
Slide 12: There are total 10 sketches in Liquid Crystal example library. I have read and understood the details of the scripts, I have run through all 10 sketches on this project.
Slide 13: Click Verify for compiling a sketch into a binary code; Click Upload to burn the binary code into Arduino board. If you see any errors in red, read the error logs and debug.
Slide 14: Start one Arduino liquid crystal sketch, use potentiometer to adjust the contrast of the liquid crystal display until you can see the characters clearly. Please rotate the knob slowly.
Slide 15: Liquid crystal display on Sketch #1 Autoscroll.
Slide 16: Sketch #2 Blink
Slide 17: Sketch #3 Cursor.
Slide 18: Sketch #4 Custom Characters
Slide 19: Sketch #5 Display
Slide 20: Sketch #6 Hello World
Slide 21: Sketch #7 Scroll
Slide 22: Sketch #8 Serial Input: After Verify and Upload the sketch #8, click Tools and Serial Monitor, type in Arduino is cool!, after hit enter, you will the message Arduino is cool! On the liquid crystal display.
Slide 23: Sketch #9 Set Cursor
Slide 24: Sketch #10 Text Direction
Slide 25:
Learn Robotics with Arduino by the following steps:
1.Check the circuit diagram and get all parts ready.
2.Build the circuit on breadboard and connect it with Arduino Uno R3.
3.Run and verify all tests included in each example.
4.Understand Arduino test sketches in each example.
5.Do some changes on the test sketches and monitor what you will get .
6.Learn and combine all the knowledge from example sketches.
7.Pick up typical examples for practice by your available time and parts.
8.Pursue an advanced project such as building a robot.
Slide 26: Create a new sketch file on Arduino I.D.E, type in the crystal ball sketch from the project book and save it by the file of CrystalBall, verify and upload the sketch. Then you will see the text Ask the Crystal Ball! on the display. Then push the button switch, you will get different answers randomly.
