LED Circuit (connected to pin 13): //Connect the long leg (anode) of the LED to pin 13. //Connect the short leg (cathode) of the LED to one side of the 220Ω resistor. //Connect the other side of the resistor to GND (ground) on the Arduino.

Wokwi only has a very basic analog circuit simulation. You won't be able to use resistors together with analog components (e.g. potentiometer or NTC temperature sensor). You can still use the resistors as external pull-up/pull-down resistors. Check out the resistor showcase by Koepel for more examples. A resistor.

Connect the Circuit Make the following connections: • Green LED: o Connect the anode (long leg) of the green LED to pin 10 on the Arduino via a 220-ohm resistor. o Connect the cathode (short leg) to GND.

# The short leg is the cathode (-). Connect it to GND. # On a momentary switch (button), connect one side to pin #4 and the other side to GND. # The display has 4 connections: GND, VCC (to …

Wokwi只有一个非常基本的模拟电路仿真。 您将无法同时使用电阻器和模拟组件（例如电位器或NTC温度传感器）。 您仍然可以将电阻用作外部上拉/下拉电阻。

2024年12月24日 · Connect the LED's anode (long leg) to a digital pin (e.g., pin 13) on the Arduino. Connect the cathode (short leg) of the LED to one end of the resistor. Connect the other end of the resistor to the ground (GND) pin on the Arduino.

Renders an axial-lead resistor with 4 color bands. Resitance value, in ohms. The value is reflected in the color of the bands, according to standard electronic color code.

Connect the anode (long leg) of each LED to pins 3, 4, and 5 on the Arduino. 2. Connect the cathode (short leg) of each LED to ground through a resistor. Below is the Arduino code that will blink the LEDs in sequence, turning one on at a time while keeping the others off.

// The use of many functions with short pieces of code. // Short pieces of code are much easier to follow and debug // The use of variables to record the state of something (e.g. onBoardLedState) as a means to // enable the different functions to determine what to do.

2024年5月21日 · I used some resistors for this, but somehow the resistor concept is not working in the simulation. Only the last two buttons on the right show any analogRead values when pressed, but both have the same value, 1023. I tested the same circuit on another simulation platform, and it worked fine there. So, the issue seems to be with Wokwi. To Reproduce
