Learn — LCD

LCD is widely used in applications to show characters and messages other than using the serial monitor. Our LCD shield kit makes it easy for you you to connect a LCD with an Arduino without using up any of the digital I/O pin except for the 2 I2C pins. As a result, you can connect more electronics into one shield, making it much easier to work with on the Arduino boards.  Part List LCD Shield Kit Female to Male Header Pins Arduino Uno R3  Arduino IDE Equipment List Soldering Iron Wire cutter Solder lead-free The LCD Shield Kit comes with the following parts.  Assembly...

LCD Lessons: Windows Installation Guide Introduction to LCD LCD Serial LCD Local (No Arduino) Arduino & 2 Wires TWI The TinkerKit! LCD also supports TWI connections. TWI stands for “Two-Wire Interface” and it’s another way to call the I2C bus technology. Basically it allows to connect multiple devices in series. This means that you can hook a large number of LCD screens, connecting them “in-line” using the two TWI ports, one for input and one for output. One of them must be the master (or you can use a TInkerKit! shield), while the others must run the TWI firmware. The...

LCD Lessons: Windows Installation Guide Introduction to LCD LCD Serial LCD Local (No Arduino) Arduino & 2 Wires TWI The LCD module can also be used by itself, without Arduino or TinkerKit! shield. That’s because it mounts the same microcontroller as the Arduino Leonardo; thanks to its micro-usb connector, it can be plugged straight into your computer and programmed from the software just like a regular Arduino Leonardo. If you didn’t do it already, download the TKLCD library. The TKLCD library is available here, once downloaded, place TKLCD in the libraries folder inside your sketchbook. How to install the library:...

LCD Lessons: Windows Installation Guide Introduction to LCD LCD Serial LCD Local (No Arduino) Arduino & 2 Wires TWI In this tutorial we use the TKLCD module from the Serial port of the TinkerKit! shield. First of all let’s get all the tools we need: the TKLCD library and a four-connectors wire or 4-pin jumper wire. To connect the LCD to the shield, we need a four-connectors wire or 4-pin jumper wire; in fact it has four holes like the serial port, one more than the regular TinkerKit! connectors. The TKLCD library is available here; if you don’t remember how...

LCD Lessons: Windows Installation Guide Introduction to LCD LCD Serial LCD Local (No Arduino) Arduino & 2 Wires TWI 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. 1. Serial Connection Using a four-connectors...
