Measure distances using ultrasonic sensors with Arduino is very common, but not only distances are measured, are also used in robotics for obstacle detection. If you are thinking of using one of these modules in your projects then we explain how the HC-SR04 sensor works. Continue reading
Continuing with sensors that can be used in aquaponics, hydroponics systems or automatic outdoor plant care, we will explain how to use a water level sensor to control the amount of water we have in a tank. The same sensor can also be used to detect if it is raining.
If you are building a system to irrigate your plants automatically monitoring the soil moisture is more reliable than set watering cycles, so that only watering when your plants need, avoiding problems by overwatering. Here we will explain how to use one of these soil moisture sensors to Arduino.
If you are automating a hydroponic system, aquaponic or just an aquarium, you know that have monitored the water temperature is critical to your system stays in top condition. Among the variety of submersibles temperature probes find a solution based on digital DS18B20 sensor. Here we explain how you can use with Arduino.
Among the different ways to communicate with an Arduino, one is to use an Ethernet Shield will allow us to our Arduino to behave as a server or a client. Here we explain it up and running in a basic way.
If you‘ve ever wanted to extract a GIF from a video and you did not know how to do this, we propose a simple way to do it with Linux. you have no excuses to generate your own GIFs of your favorite videos.
The time-lapse video are an excellent way to acquire a new time perspective of our environment. One of the most common uses is to observe the growth of plants, creating videos that compress days in just a few seconds. If you want to create your own time-lapse video below we explain how you can do so using a mobile phone Android as an IP camera and a Raspberry PI for storage and further processing of the video.
One of the first tools you need to build your electronics lab is a power supply. If you do not have much money to invest you can recycle a ATX power supply through this board.
To control voltage fed else than we can use Arduino devices most common method is by relays. The relays provide us with electrical isolation between Arduino and the device in question we want to control such a lighting system, an engine AC or DC. Thus by means of Arduino digital pins we put on and off electrical appliances with a 0 or a 1.
