Smart LCD with Automatic Brightness Adjusting Using Arduino and LDR Sensor Here is a simple Arduino project that focuses on adjusting the brightness of an LCD screen whenever there isn’t sufficient light in a room. The Arduino reads the surrounding light intensity using an LDR sensor. The room temperature and humidity range will also be displayed

In this project, we will use a 4Duino and several IR sensors to create a simple pet food dispenser. 4Duino checks whether a food tray contains enough food or not. It is programmed to read IR values from each sensor. These values change depending on the amount of food in the container. The feeding time can

In this project, we will use several IR sensors to check if an item from an inventory box is present or not. This project makes use of a 4Duino-24 to check whether an item is present or missing from the inventory. The 4Duino uses its analog pins to read the values from each IR sensor.

Since the industrial age, we humans have been progressing quickly. As we make advancements, we simultaneously harm our environment, leading to its eventual degradation. Currently, the issue of global warming is a concerning danger and even the quality of the air we breathe is becoming a serious concern. Monitoring air quality is becoming increasingly important.

Story We (most of us) really like Arduino because it’s possible to make cheap clones, lots of libraries, examples, forum support and community out there. Outside Arduino world, I like Cypress PSoC for some of its cool features like Graphical IDE, APIs, great features and understandable documentation. I have bunch of PSoC® 4 CY8CKIT-049 4xxx

I came pretty close to calling this one “Magnets, How do they work?” But I thought that might confuse more than it would amuse. All jokes aside, hall effect sensors are pretty cool, and also pretty simple to use, but there are a few types you may not know about and I figured it would

In past tutorials, we have covered temperature, color, time, direction, but never distance or proximity. I think I strayed away from this because most of the lower cost proximity sensors are pretty drop-dead-simple to use and thought it might not be that useful. But the time has come, I’m writing about some distance/proximity sensors. While
Are we getting close? Proximity Sensors + Arduino Continue Reading
Note: When referring to Arduino below, this works in the same way on the emonTx which is arduino-based. The DS18B20 is a small thermometer with a built in 12bit ADC; it can be easily connected to Arduino digital input. The sensor communicates over a one-wire bus and requires little in the way of additional components.

John has been working to recover components from old power supplies and available trash electronics, in order to build controllers to power stepper motors and other mechanisms for the FabLab. Intro The Arduino microcontroller board is able to supply a current of 40mA from its output connections. These digital outputs are fixed at 5V “ON”
