Today, I will build a numeric keypad based on the Raspberry Pi Pico. I will create a simple orthogonal numeric keypad with 20 switches. Then, I will introduce how to install KMK firmware on it. KMK can be installed on Python-based microcontrollers. It is used for some simple projects, from numeric keypads to full-sized keyboards. … Read more
Hello everyone, I am a beginner in electronics. Today we will analyze an AC 220V to DC 5V resistive-capacitive voltage reduction circuit. The resistive-capacitive voltage reduction is a circuit that can convert AC mains power to low DC voltage with very few components and at a very low cost. It is often used in devices … Read more
Common Symbols for Potentiometers The resistance of a potentiometer, also known as its nominal value, refers to the resistance between its two fixed ends. The common symbols for potentiometers are shown in Figure 3. Switch Potentiometer Symbol 1. Enter the main interface of Multisim and directly select the icon button. 2. Next, click on BASIC_VIRTUAL. … Read more
Someone just asked me how to display circuit nodes in Multisim 12. After I told him, I suspected many forum friends might not know either, so I’m leaving this post for the convenience of everyone: Select netnames show all Now, if you check the circuit again, the circuit nodes will be displayed.
Multisim is a simulation tool developed by National Instruments (NI) based on Windows, suitable for the design of board-level analog/digital circuit boards. It includes graphical input for circuit schematics and circuit hardware description language input methods, with rich simulation and analysis capabilities. Engineers can use Multisim to interactively build circuit schematics and simulate circuits. 01 … Read more
