![]() On the contrary, a LOW value means that 0V (=GND) is supplied to the pin. Different boards may have different voltage values (5V for some Arduinos). The HIGH value actually means that a voltage of 3.3V is supplied to the pin. There are several pins that can be connected to external devices, and through each pin, you can output LOW or HIGH or read what value ( LOW or HIGH) comes into each pin. Digital I/Oĭigital I/O is the most basic function of computers used for physical computing, such as the Raspberry Pi Pico. There are three main types of wires: M-M, M-F, and F-F, depending on whether both ends of the wire are in the form of a pin (M - Male) or a form of hole that can be inserted by a pin (F - Female). Jumper wires are used for connecting parts together. That doesn’t mean that the calculation method is very difficult, but it will not be covered in this course, and if you are curious right away, please refer to other resources. In this course, I will tell you the required resistor value, and you can easily find out how much resistor value is required for the sensor or part that I want to use just by searching on the Internet. (Even if it is not necessarily 330Ω, it is safe to use a similar value.) There is no need to worry too much about calculating the resistor value. ![]() ![]() ![]() We will use 330Ω here and the color is “Orange-Orange-Brown-Gold”. You can see a band of different colors on the body of the resistor. To adjust the appropriate current, you need to calculate the appropriate resistor value. Resistor is a component that prevents current from flowing and allows an appropriate amount of current to flow through it. ![]()
