These are some great DIY projects that you can do for cheap.

Abstract: This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the ...

This project demonstrates how to interface a DHT11 temperature and humidity sensor with an ESP8266. The code reads the temperature and humidity from the sensor and displays the data on the Serial ...

The DHT11, 21, 22, 33 and 44 are relative inexpensive sensors for measuring temperature and humidity. This library can be used for reading both values from these DHT sensors. The DHT11 only returns ...

Increasing population and demand for animal-derived products has raised the need for improved efficiency in managing and controlling animal production. Given this context, the project aimed to develop ...

Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...

This page features a curated collection of Arduino Uno projects designed specifically for beginners and intermediate learners. Arduino Uno is the most widely used board for learning electronics, ...
