We will build a temperature sensor in this tutorial and connect it with an App. It uses an DHT11 temperature & humidity sensor and Bluetooth communication with a phone. We use a BLE-Nano here, but you can also use a regular Arduino Nano. In step 3, there is an alternative offered for the part that … Continue reading Tutorial: build a connected temperature sensor
Information on how to use an 0.96 inch OLED Display (128*64 pixels) with an Arduino. This is an i2c module, which makes it easy to connect as it has only 4 wires. It is assumed you have installed the Arduino IDE and have some basic understanding of using electronics and wiring a breadboard. In addition, … Continue reading Use an OLED Display with Arduino
This tutorial uses the Arduino Nano, but you may also use an Arduino Uno. You might need the Arduino Nano pinout diagram or an other diagram for your particular model of Arduino. We are going to use the diagram below to build it. But if you are inexperienced each step is explained in detail. First, … Continue reading Use DHT11 temperature and humidity sensor with display
Information on how to use displays in combination with the EVShield. Small (oled) displays can be a great addition to a robot powered by an EVShield, like the Rover. It can be used to display all kinds of information about the status of the robot, like the battery voltage, speed etc. The Lego display is … Continue reading Using various displays with EVShield
Some example sketches for a 2.8 TFT Shield touch screen: A numeric keypad, a basic paint program, an image viewer and a calculator. The shield comes with an SDcard slot. The image viewer reads images from an sdcard You mount the shield onto an Arduino Uno (or Leonardo) like this: These examples have been tested with … Continue reading Touch screen examples: keypad, paint, image viewer and calculator
