The goal of this tutorial is to detect when is coffee machine is going to be out of water before it happens. Indeed, using the pump of the machine without water may damage it. We will do it in a total non intrusive way, we only put an Arduino board with an accelerometer on the cof...

Essentially, a water pressure sensor provides information aboutwater pressureand temperature. To get this information, you need to connect a water pressure sensor with a socket in your outdoor device. You can use this information in your home, washing machines, and heating systems. If you want ...
The Arduino Uno is capable of regulating things like a pump that delivers water to plants based on their moisture levels. The Uno is even used inthe Open Energy Monitor, a commercially available open-source energy monitoring device that tracks solar PV generation and electricity use. ...
In this tutorial we will learn how rotary encoder works and how to use it with Arduino. A rotary encoder is a type of position sensor which is used for...
How ToThis DIY Arduino Bicycle Safety System Includes Turn Signals, Brake Lights, Strobe, and More! ByNelson Aguilar Bicycle As dedicated bicyclists are well aware, riding can be very dangerous. Now that daylights savings time has ended in the United States, darkness appears quicker, and the ni...
Some devices can track how much energy each appliance is using and command power hogs to use less. Smart home technology promises tremendous benefits for elderly people living alone. A smart home could notify the resident when it's time to take medicine, alert the hospital if the resident ...
Let's build a small cooler to keep the water cool using Arduino, This is possible thanks to the use of the thermoelectric TEC1-12706, which we will use in this article: This pellet uses the Peltier effect to generate very low temperatures (often below 0) on one side of the pellet and...
Arduino decides the amount of time and, hence, the amount of water to be pumped in the field, using a DPST relay. A siren in parallel sounds to indicate pump in on condition. This application is helpful in saving water. Application 4: Unmanned ground vehicle for inhumane environmen...
present, the switch is off. When base voltage is present, the switch is on. To provide the LED with sufficient voltage, we use the first transistor, which is controlled with the signal from the photodiode, to control the second transistor. This gives the LED power directly from the ...
