Description The MAX31850/MAX31851 cold-junction compensated, 1-Wire® thermocouple-to-digital converters perform cold-junction compensation and digitize the signal from a K-, J-, N-, T-, S-, R-, or E-type thermocouple. The converters resolve temperatures to 0.25°C, allow readings as high as +1768°C and as low as -270°C, and exhibit thermocouple accuracy of 8 LSBs (2°C) for temperatures ranging from …
Although this kind of voice effect can be obtained by means of some audio computer programs, depending on the equipment you are using this microphone input and loudspeaker output could be more versatile. This design uses a variable gain microphone preamplifier built around IC1A, a variable steep Wien-bridge pass-band filter centered at about 1KHz provided …
Waveform generators (also called function generators) are useful for testing and debugging circuits. They can be used to test the frequency response of electronic components like op amps and sensors or to characterize and troubleshoot audio effects boxes and pedals. This waveform generator shield is powered by an Arduino. It outputs four waveforms: sine, triangle, …
This is an Example of how you can use the Arduino to monitor various environmental parameters And display them on a LCD screen. Note: I Added a Real Time Clock!! To see the steps, added parts and Sketch I added new steps.. Arduino uno R3 or compatible …
After finishing my hexapod I needed another project Over the last year I have bought numerous small break out boards on Ebay. So I came up with the idea to make an Arduino MP3 alarm clock. The idea is simple, an LCD that shows the date and time. A couple of buttons to set an …
I find the CPU/Memory/HDD/Net stats as something I regularly take a look at. But these stats live a virtual live. If they are a desktop gadget they are pushed in the background by other programs or they are doomed to live like a little bar down in the taskbar. The desire to somehow free the …
Occupying a footprint of just 2.57×3.24 mm, the STA333IS single-chip digital audio system from STMicroelectronics furnishes up to 20 W of audio output power for use in space-constrained LCD and LED televisions, docking stations, and digital wireless speaker systems. With is wide operating voltage range of 4.5 V to 18 V, the device is also …
The following is a white paper by Silicon Labs with an innovative new process and technology that I believe deserves some level of detail and explanation for informative and educational purposes for EDN readers. Learning about this technology will help all designers give birth to new ideas and architectures as well as help those other …
Apple this week is celebrating the five year anniversary of its Apps Store. If you go to the store, you’ll notice Apple is giving away five games and five apps to celebrate the anniversary. When it opened its virtual doors, the Apps Store did so with a mere 500 apps. Now, it showcases more than …
Note: By “beginner’s guide”, I mean a guide written by a beginner. (I made it at Tech Shop SF, during my first weeks!) I have some technique tips to share, but for more in-depth questions, Google is your friend. Solder paste allows you to populate a board with many tiny components, without straining your eyes …
