Interfacing a Thermocouple with Arduino platform can be easily done by integrating a MAX31855 to your project. This IC is a Cold-Junction Compensated Analog to Digital Converter amplifier especially design for use with a Thermocouple. The converter provides 14-Bit of digitized temperature data with 0.25°C resolution and can be used with most of common Thermocouple … Read more
In this post I’ll show how to interface a Keyestudio 40 RGB LED 2812 Pixel Matrix Shield with Arduino UNO compatible board. Each LED on this shield has an integrated chip WS2812 and can be individually controlled. Attached Arduino code makes use of these features making the shield to behave like a simple 7-Segment counter … Read more
Arduino based 3 Digit Timer with LED Display module is a relatively simple design. Recently I’ve published a number of similar projects that essentially perform the same task. You set up an initial value via some kind of user interface like push button or a keypad and the circuit counts down to “000”. The display … Read more
The topic of this post is building sine wave generator based on Arduino UNO and PCF8591 8-bit A/D and D/A converter. For similar design with PIC micro-controller look at this link. Raspberry Pi version based on MCP4725 DAC available at this link. PCF8591 is a single-chip low-power 8-bit CMOS data acquisition device with four analog … Read more
In this post I’ll show you how a 12 bit DAC model MCP4725 can be connected and controlled by Arduino or a compatible board. Similar design based on Raspberry Pi platform can be found at this link . Wire.h and Adafruit_MCP4725.h libraries were used in this design. Attached Arduino sketch generate a triangular wave just … Read more
