How to use this When the simulator starts up you will see an animated schematic of a simple LRC circuit. The green colour indicates positive voltage. The grey colour indicates ground. A red colour indicates negative voltage. The moving yellow dots indicate current. To turn a switch on or off, just click on it. If […]
ON Semiconductor, driving innovation in energy efficiency, has introduced a new MP3 capable device to support both record and playback in portable MP3 audio applications where there is a strong requirement for miniaturization, reduced bill of materials (BoM) and reduced cost. The LC823430TA audio processing system provides a single-chip solution by integrating digital signal processing

The Goals Sometimes you need to check one circuit and test some of its nodes. Usually a tester in voltage mode is a good solution, but it has a pair of problems. First, it measures about zero both when the node is driven at zero volts and when the node is floating (not driven at

In Circuit Serial Programming is a method of directly programming a Microchip PIC or Atmel AVR while in they are connected to a circuit, as opposed to programming the chip ahead, and only then soldering it to a circuit. There are many benefits to ICSP, but also some important design considerations which I will try

How to interface LED with Microchip’s PIC microcontroller? How to connect LEDs to a PIC microcontroller? LED interfacing is the stepping stone for microcontroller development. This is a simple embedded program for PIC 16F877A to interface LEDs, suitable for beginners who wish to study basics of embedded microcontroller programming. The program is developed through Micro
In this article, we will show how to drive a 7 segment LED Display using a PIC16F690 microcontroller. This PIC16F690 microcontroller chip is actually a part of the PIC2 Starter Kit, so we will actually be using this starter kit to drive the LED Display. A 7 Segment LED Display is an electronic device that

In a previous article I described how I designed the circuitry to control functions of the asparagus harvester. After bread boarding up a test circuit and doing some initial programming I decided a re-do was in order. I found I had a lot of unnecessary redundancy and I also decided to put the air regulation
Microcontroller ( MCU ) circuits TINACloud supports a lot of PIC, AVR, 8051 and ARM microcontrollers; new MCUs are constantly being added. You can see and modify the program running in the processor and, of course, you can create your own code. There are two ways of providing the program for microcontrollers in TINACloud. You
