arduino alarm system

    This uses an Arduino microcontroller and a passive infrared or PIR light sensor to detect invisible infrared light. I created the project as a way to learn digital input and output. In this case, the PIR sensor is the input and the output is an LED and a really noisy, piezo buzzer it’s, […]

arduino 9v motor

    This means you have to design your own solution, which doesn’t always work. It must be an easier way. This is a Lego track, switch the designs been around for 25 years now, but even new versions work on the same principle, which is this annoying little yellow lever. However, with a few […]

arduino analog output

    Let’S talk a little bit about how analog inputs are set up on the Arduino boards. Here I have the uno, the mega 2560 and the nano boards all of these allow for analog input options and on all our Lino’s. There is a 10 bit analog digital converter that allows you to […]

arduino oxygen sensor

    . They look identical and you can probably tell them, apart only by the labels., Both require exactly the same connections, but they detect different gases. In this tutorial. I’Ll show you how to use one of them with Arduino. We’ll, be reading values from the sensor and make the Arduino light an […]

arduino 24v input

    The model number is s: 5. 5 c 3, 5 30, and this has an operating voltage of between 10 and 30 volts DC, and that is too high for the Arduino to handle because they can only handle 5 volts. So we’re going to be using a voltage divider to reduce the […]
