There are now small infrared cameras in the form of break-out boards that are very affordable and easy to integrate into automation projects. Surprisingly, they often use the I2C protocol to transfer data. Today, we show you how to use a Yocto-I2C to interface this type of camera.

Reading a potentiometer, push button or other resistive sensor via USB is a priori not very complicated. By the way, the Yocto-Knob is one of the very first modules we put for sale more than ten years ago. However, depending on the applications, the needs are not always the same. Therefore, over time we added new settings in order to refine the measures. Let's see this in details...

Two years ago, we told you about reed switches, especially to warn you about the difficulties that you can encounter when you want to use them to build a rev counter. But we had somewhat forgotten to tell you about Hall effect sensors, which can be a welcome substitute.

When you must design a system that sends back measures through a GSM connection, there are two physical quantities that you want to estimate: que quantity of transferred data and the power consumption. We already had the opportunity to provide orders of magnitude for data consumption in a previous post, but we are going to see today how much power is needed to send back data periodically through a 3G or 4G GSM connection.

You should normally power Yoctopuce modules with a voltage between 4.75V and 5.25V, which is the standard operating range for USB devices. But what happens when you go beyond these limits, even temporarily and without meaning to? What are the cases that can cause lasting damage? This is what we will explain to you...
