We usually see electronic weighing machines in stores that display weight instantly when an object is placed on the weighing scale. Here, we are going to make a similar weighing machine using an Arduino and a Load Cell that can measure up to 40kg. If needed, it can be increased by using a Load Cell with higher capacity. Load Cell and HX711 Sensor Explained Materials Required: Component Quantity Arduino Uno 1 Load Cell (40kg) 1 HX711 … Read more
Hall effect sensor is a sensor whose output is modified by a magnetic field. This means that the output signal it produces is a function of the magnetic field density around it. When the magnetic field is greater than a specified set value, the sensor is able to detect it and generate an output voltage known as the Hall voltage to indicate its detection. Hall Effect Sensor Hall effect sensors are commonly employed due to their versatility. They are typically used … Read more
Hello, have you ever wanted to control an LED just by making a noise, like clapping your hands? Well, you’re in the right place! In this guide, I’ll show you how to use a sound sensor with an Arduino Uno to make that happen in a super simple way. Don’t worry if you’re new to … Read more
