The Arduino Uno R4 WIFI provides no pull-ups on the board. The SEK SCD41 board we are going to connect to the I2C Bus on the pin header has no pull-up resistors built in. Thus, we need to connect a ...

The ENABLE pin switches the stepper drive on or off. The polarity of the pin is active low, so the stepper drive is enabled when the pin is logic low and is disabled when the pin is logic high. When ...

It is easy to forget, but the Arduino does use C++. Typically, the C++ part is in the libraries and the framework and most people just tend to code their main programs using a C-style just using th… ...

Digital I/O using Arduino functions. For an Arduino IDE design, there are two steps placed in the “Setup” coding block: Set the pin mode during setup. Enable or disable an internal pull-up resistor if ...

I2C also requires pull-up resistors on the data (SDA) and clock (SCL) buses. We used two pull up resistors soldered to the 5 volt output of the Arduino shield and SCL/SDA.

Compiling SPL Libraries on Arduino IDE. As mentioned earlier, we can also use the SPL library on Arduino IDE. If you remember, in our previous STM8S GPIO tutorial, we wrote a code to blink the ...

Circuit Diagram. The complete circuit diagram this Arduino Function Generator is shown below. As you can see we have an Arduino Nano which acts as the brain of our project and an 16x2 LCD to display ...

You have to pull an extra wire from the sensor’s input voltage to your Arduino’s AREF pin, so you know what the actual voltage at the end of the cable is, so you can estimate the 10-90% range.
