In this instructable I will show you how I connected a serial LCD 16X2 to an Arduino UNO. There are lots of instructables and tutorials showing you how to connect a regular LCD to an Arduino but not many showing a serial LCD and on my Arduino the PINS to attach the UART pins are hid...
Let’s connect our LCD to Arduino. First, connect +5v and GND pins from the Arduino to the breadboard power lines. Plug your LCD into the breadboard and connect Pin1 to ground and Pin2 to the +5V rail. Next, put the potentiometer on the board and connect two side legs: one to +5v...
There are a couple ways to use I2C to connect an LCD to the Raspberry Pi. The simplest is to get anLCD with an I2C backpack. But the hardcore DIY way is to use a standardHD44780 LCDand connect it to the Pi via a chip called thePCF8574. The PCF8574 converts the I2C signal sent ...
You can use the path C:\Users[user]\Documents\Arduino\libraries, and I'm sure this is for the new Arduino IDE 2.0, as I'm working with the legacy Arduino IDE. I'm happy I learned how to setup this wonderful IDE. But I got back to the legacy Arduino IDE, it's more convenient f...
LCD Shields To create a user-friendly interface that enables users to display what they want and make selections, among other things, the LCD Keypad Shield is an Arduino-compatible board. It has an LCD with 1602 white characters and a blue backlight. Five keys make up the keypad: select...
16X2 LCD Display We have another tutorial on the DHT11 for theArduinothat goes into detail on relative humidity and how the DHT11 measures it. So instead of repeating all of that here, check outHow to Set Up the DHT11 Humidity Sensor on an Arduino, then come back for the specifics on...
Example code HC-SR04 with I2C LCD and Arduino To display the measured distance on a2004 or 1602 I2C LCD, all you have to do is make the following connections and upload the code below. The HC-SR04 sensor is connected in the same way as before. ...
