![]() ![]() The Arduino IDE will open up a dialogue box from which you can search for the library. Check if any reads failed and exit early (to try again). The easiest way is to go to Sketch > Include Library > Manage Libraries. Sensor readings may also be up to 2 seconds 'old' (its a very slow sensor) There are 2 kinds of this module: 4 Amps and 4.5 Amps. ![]() A key feature of this module is that you can change the microstep settings by the built-in switches on the driver. This module could control a two-phase stepping motor. The I2Cdev.h header also includes it if necessary, but. The TB6600 is an easy-to-use professional stepper motor driver that you can adjust its microsteps. Click here to compare the RF 433MHz transmitter/receiver on several stores and find the best price. If youre using the Arduino Wire library, make sure you include Wire.h in your main sketch file. Connecting a Three Pin DHT11: Connecting a Four Pin DHT11: R1: 10K Ohm pull up resistor Display Humidity and Temperature on the Serial Monitor. Reading temperature or humidity takes about 250 milliseconds! Price: 1 to 2 Specifications RF 433MHz Transmitter Frequency Range: 433.92MHz Input Voltage: 3-12V Price: 1 to 2 Where to buy You can purchase these modules for just a few dollars. Wiring the DHT11 to the Arduino is really easy, but the connections are different depending on which type you have. Developers can either connect peripherals with jumper wires or mount. Wait a few seconds between measurements. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. #define DHTPIN 2 // what pin we're connected to In the sketch you can see that I use the Adafruit DHT library that is very simple to use and if you follow the code line by line your project will have zero errors. ![]()
