You need to wire 8 Max6675 ics to a microcontroller. You can parallel all the clock inputs. The NCS lines of numbers 1 and 2, 3 and 4 etc can be connected together. The SO lines of all the odd numbered Max6675 can be connected together, as can the even ones.....

This is a control of servo motors in software programming using PIC 16C71 microcontroller. The input signals are between 0 - 5V delivered by ....

The hardware configuration when using multiple 1-Wire temperature sensors like the DS1820 is very simple, as illustrated in the block diagram below. A single-wire bus is used for communication between the microcontroller and the temperature sensor. It is....

My daughter wanted a way of measuring static for her science project. While scanning through an old copy of Getting Started in Electronics by Forres....

This ISP Programmer can be used either for in-system programming or as a stand-alone spi programmer for Atmel ISP programmable devices. The programming interface is compatible to STK200 ISP programmer hardware so the users of STK200 can also use the software....

To operate a microcontroller, you need some basic components to support it and the circuit we call it basic circuit. The components needed are very common and you can find them at any electronics store out there. Here, i will share the schematic of basic....

The basic design of this project will use a Atmel AT89S8252-24PC Microcontroller, since this micro has 2KB of EEPROM that can be used to store data during runtime. A ADC0838CCN analog to digital will be used to receive up to 8 inputs from sensor devices,....

How to interface a microcontroller to the phone line. The tones you hear as you enter numbers on your phone can remotely control devices. Learn how to use these DTMF tones in your microcontroller projects. This article was submitted by Mayank Magoo as part....

This project describes how to build a simple programmer for the Atmel ATmega8 single-chip microcontrollers. This should be considered a "hobby grade" programmer as it does not use a variable Vcc and uses the "Serial Programming Algorithm. " The ATmega8 can....

Boost circuits are an awesome way to power microcontrollers. Instead of 4AA batteries or a 9V (usually regulated down to 5V or 3. 3V), you just boost one or two AA`s up to your desired voltage. The only problems are that boost ICs (like these two ) are a....

So this is a bit of a continuation on my 555 timer based PWM controllers, but now using microcontrollers and MOSFETs instead of 555 ICs and transistors. I made 2 versions, one with switches for speeding up and down and the other with a potentiometer like the....

and C code for a PIC frequency counter operating up to about 50MHz. The project uses an HD47880 LCD for the display and uses timer 1 to count edges of the input signal....

As time goes by, microcontrollers become more powerful, cheaper, and smaller. A typical micro of the past could have had 40 pins and no internal memory. On the contrary, modern J-series PICs are made with 96K program memory and 28 pins. We can drive a lot of....

When you are using LCD in 4 bit mode you have to send data two times where in 8 bit mode you only have to write once, this ultimately keeps your microcontroller more busy with LCD. If you are doing only a few things with your microcontroller then its ok you....

A Mobile Controlled Robot is a mobile device, which provides wide-range of wireless control ability to your robot unless your cell phone gets out of signal....

Atmel joins NXP, ST, Luminary Micro (now TI), and Toshiba as a microcontroller vendor to use the ARM Cortex-M3processor core. As a presumed replacement for some of their ARM 7 based MCU products, Atmel`s first Cortex-M3aims to differentiate from the rest by....

Here is calendar digital circuit. this circuit using Microcontroller is an advanced digital calendar, which displays the Date, Day, Month over the LED display. All the above systems are controlled by the Microcontroller. It has an 8 bit Microcontroller which....

This is a real time clock by using 89c51 micro-controller, clock`s data format is hour:min:sec, and it is displayed on 16x2 LCD, the code has been tested and compilled on Keil uVision compiler, circuit diagram for the project is shown below...

The circuit diagram is shown to the right. You can get a larger version or a PostScript version if you prefer. The design is based around a Microchip PIC16F628A microcontroller. At the time of writing, this device is available for less than one pound from....

For the most part we live in an analog world and when using a microcontroller, it is often necessary to be able to convert a digital value into its analog equivalent (or, for that matter, an analog value to a digital value but that`s not what this post is....

The MAXQ3210 ia a powerful RISC microcontroller. This device have features and capabilities to make it compatible for battery-powered applications that detect....

this project use PIC18F25K20 microcontroller to detect if the sensor change state and it will emit a sound from the speaker or piezo, the MCU also detect the voltage of the battery in the startup, the algorithm it s very simple use an interrupt on change to....

The microcontroller (MCU) is responsible for sending variable voltages over time (just like a traditional LFO) to an effect that can be modulated by a voltage, or a pot on a traditional analog effect that can be replaced with an optoisolator/vactrol. Here`s....
