tinkerkit lcd module schematic in stock

Now move the content of the downloaded “Tinkerkit Drivers” folder inside the Arduino drivers subfolder. At this point it’s important to know that the TinkerKit! (and also the Arduino) boards works in this way: they have two “states”. One is called “bootloader state” that lasts for about seven seconds after you plug the board into the usb port, then it goes into “sketch mode”. Every time you power the board (or reset it) it goes into bootloader mode, then sketchbook mode after seven seconds. We have to install a driver for each mode.

Press the reset button on the TKLCD board, without closing the Device Manager. Once restarted, for the first 7 seconds, while it’s in bootloader mode, you should see an unknown “Arduino Leonardo” in the device list, right click on it and select “Uninstall“. A pop-up confirmation window appears, press OK. (sometimes Windows shows the “unknown device” at the top of the list and not under the “ports” sub-menu)

Now that we have uninstalled the Leonardo drivers for the LCD, we have to install them again. Press reset again on the TKLCD board, and when the unknown “Arduino Leonardo” pops up from the ports menu, right-click then “Update driver software“

Press the reset button, Windows should see a “TinkerKit LCD bootloader”, then after 8 seconds it turns again into an unknown Arduino Leonardo. Repeat the right click, update driver procedure that we did in steps 12 to 14.

Now the LCD is installed on your Windows PC. After installing it, you can select the Arduino Leonardo board from the IDE every time that you want to use the TinkerKit! LCD.

With the TKLCD module you can write text on the module"s screen in a few minutes. It has an LCD display on board and it requires a dedicated software library that is available here.

The LCD can be used like a regular module by plugging it into the TinkerKit! shield or as an independent component; it has in fact a microcontroller and a USB port on board that make it a fully-fledged LCD-shaped Arduino Leonardo.

Please notice that the way you connect your LCD module is really important for declaring it in your code:use TKLCD_Serial lcd = TKLCD_Serial() if you connect it to the Serial of your TinkerKit Shield

You actually have to go to the 2 wire i2c tutorial to see the pinout of serial though Derp its not in the serial tutorial go figure. like so many problems with tinkerkit it was a great Idea and supported by arduino and radioshack they were not good at support or tutorials etc. so they failed.

Pin 9 is defined as "BL" (backlight probably) but it is tied to VCC +5 volts via a trace on the board. So the Adafruit VCC pin should be ok at Pin 9. The Adafruit backlight at Pin 1 would be at +5 volts turning the backlight on all the time which is not ideal but there is no PWM pin handy to modulate the intensity except on the TinkerKit connectors. One could cut off Pin 1 on the display (or not solder it in) to have it permanently off.
