Before you can use the DHT11 on the Arduino, you’ll need to install theDHTLib library. It has all the functions needed to get the humidity and temperature readings from the sensor. It’s easy to install, just download the DHTLib.zip file below and open up the Arduino IDE. Then go ...
Interfacing XBee Module with Raspberry Pi Pico & MicroPython February 2, 2025 How to set up & interface XBee Module with Arduino (Tx & Rx) February 2, 2025
To use this sleep mode write the SM[2,0] bit to ‘001’. The mode stops the CPU but allow the ADC, external interrupt, USART, 2-wire serial interface, Watchdog, and counters to operate. ADC Noise Reduction mode basically stops the CLKCPU, CLKI/Oand CLKFLASH. We can w...
The DHT11 is a basic,ultra low-cost digital temperature and humidity sensor. It uses acapacitive humidity sensorand athermistorto measure the surrounding air. This sensor can be easily interfaced with any microcontroller such asArduinoorRP2040 Raspberry Pi Picoto measure humidity and temperature ins...
The NewPing library also makes it easy to interface with ultrasonic sensors while using only 1 I/O pin. This can be handy if you have very few I/O pins available or if you want to use a 3 pin ultrasonic sensor like theParallax Ping. ...
with a personal computer, and use software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device. In this project, I’m usingSD-Cardto store data with the help of Arduino....
The serial interface is enabled". Before these changes fully take effect, we must first restart the Raspberry Pi. To do this first get back to the terminal by pressing Enter and then ESC. Type the following command into the terminal on the Raspberry Pi to restart it. sudo rebootCopy 8. ...
This article is an introduction to the MQTT protocol. MQTT stands for Message Queuing Telemetry Transport, a simple messaging protocol suitable for communication between IoT devices.
he will be using Arduino’s integrated development environment (IDE) and the C/C++ programming language. There are different ways to get to the same result, so pick the board and programming language that you are most familiar with. There is a lot of ground to cover, so let’s jump righ...
The best trick to get extra inputs into the ESP8266-01 is to use an I2C interface. One choice is to use GPIO0 and GPIO2 as the I2C bus. The pullup resistors needed to get the module to start up correctly can double as the I2C bus pull-up resistors and the other, slave, componen...
