Lastly, place the pi inside the case, cover with the cap, and plug it in!
Once dried, apply a seam of glue to the attachment point on the inside of the case. Position the topper how you would like it to sit in the top hole and make a seam of super glue around the top. After drying, feed the four cables through the top of your pi case and attach to the correct pins (DOUBLE-CHECK YOUR WIRING). Use clamps to ensure you have an even, snug fit. Put a small amount of super glue on the attachment point of the front plate and the base. There is a slight draft to ensure a snug fit. DO NOT OVERTIGHTEN as at screws will strip out the plastic from the integrated holes. Use the 4 M3x8 screws to mount the LCD display to the pi housing. The screen should only fit in the hole one way. I found it easiest to unplug and mount my LCD screen prior to gluing. Make sure to sand down all areas that will be contacted by glue. Depending on printer tolerances, your parts may not fit together perfectly (use sandpaper or a knife to trim them to size). Now, Reboot your Pi and see if it works!Īll parts were designed to fit snug to make gluing easier. Type Crtl-X, Y (for yes), and Enter to save. At the bottom of all of the hashtagged text, input the sudo python (TYPE IN THE LOCATION OF YOUR CRYPTOTICKER.PY FILE). Open the terminal and type the following:. (Example: /home/pi/Desktop/CryptoTicker.py) First, note the location of the CryptoTicker.py file. Use a phillips screwdriver on the little blue box on the back of the I2C unit to adjust the contrast of your screen. This is also a great time to adjust your contrast. If your message comes up, Congratulations! your LCD is ready to use. Press "F5" to save and run your python code. Mylcd.lcd_display_string("Hello World!", 1) Enter the following: import I2C_LCD_driverfrom time import *. Let's write "Hello World!" to the display. Using the example, line 22 would be changed to: "ADDRESS = 0x21" On line 22, enter your I2C address that we found in the "Install Necessary Components" section. 
On line 19, you will want to change "I2CBUS = 0" to "I2CBUS = 1". #Cryptocurrency ticker el15 code
Copy this code from GitHub user DenisFromHR ( link) and save it in a file named "I2C_LCD_driver.py".
Take note of your number, you will need it later. In the example, the I2C address is "21".This will show show you a table of devices connected to your pi ( link).

Wait for the install to complete then enter:.The LCD screen should light up but nothing will be displayed. Once you have double and triple checked your connections, solder the jumper cables to you Raspberry Pi.Pi Pins->LCD Pins GPIO 8 -> SDA GPIO 9 -> SCL 5.0 VDC (either output) ->VCC Ground (any output) -> GND Attach jumper cables using the following (Raspberry Pi Zero W pin out ):.Shutdown and unplug your Pi (wait for the activity LED to stop flashing before unplugging).Choose "Yes" then exit the configuration menu.Select "I2C Enable/Disable automatic loading" ( link).Find and select "Advanced Settings" from the menu ( link).Open the Raspberry Pi terminal ( link) and type the following commands: sudo raspi-config Give that article a read if you get lost: link Enable I2C Much of the info for this section was pulled from an article posted on, including extra code to make your text do fun things.
