In this tutorial, we’re going to look at EEPROM memory on theArduino. EEPROM memory is a type of external memory that the Arduino can write to. You can use it to store files and log sensor data. To demonstrate how to useEEPROM memoryon the Arduino, we will build a project that read...
are the T0-92, TO-126, TO-220 and TO-3. We will try to understand all these specifications of transistors and also learn how to use them in practical circuits.
The DHT11 measures temperature with a surface mountedNTC temperature sensor(thermistor) built into the unit. To learn more about how thermistors work and how to use them on the Arduino, check out ourArduino Thermistor Temperature Sensor Tutorial. With the plastic housing removed, you can see the...
Conductive ink-based flex sensors are unipolar sensors, which means the change of resistance is true only if you bend it in one direction. Bending it to the other direction does not change its resistance. Arduino Interface Circuit Just like most resistive sensors (like a thermistor), the best ...
as part of a beginner Arduino starter kit) Temperature compensation (i.e. maintain resistance to compensate for effects caused by changes in temperature in another part of the circuit) Used in wheatstone bridge circuits How Does a Thermistor Work The working principle of a thermistor is that i...
Fuses and PTCs -- devices which are generally used to limit large inrushes of current -- each have their own unique symbol: The PTC symbol is actually the generic symbol for athermistor, a temperature-dependent resistor (notice the international resistor symbol in there?). ...

The bare minimum code in Arduino IDE Inputs and Outputs Inputsandoutputsare pins on the Arduino that you can use to either get information into the Arduino (input) or make things happen outside the Arduino (output). For example, if you connect an LED to an output you can turn the light...
I am using the USB-Serial Bridge (CY7C65211) that is included with the prototyping kit, and just wiring P0.4 and P0.5 to the Serial Bridge. But I've never heard that it's necessary to use the SCB component, in other projects I used the UART v2.5 component, and it worked just fin...
Ramps 1.4 + Arduino Mega 2560 Pros Ramps 1.4 + Arduino Mega 2560: Cheap Easy to use Easily modifiable Can use digital or analog drivers Widely available. Cons Ramps 1.4 + Arduino Mega 2560: A lot of knockoffs out there, Often have weak mosfets that fail or overheat ...
