*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC Sous-vide (/suËËviËd/; French for “under vacuum”) is a method of cooking food sealed in airtight plastic bags in a water bath for a long time—72 hours in some cases—at an accurately determined temperature much lower than normally used for cooking, typically around […]
Generate sound or output analog voltages with an Arduino. This Instructable will show you how to set up a really basic digital to analog converter so you can start generating analog waves of all shapes and sizes from a few digital pins on an Arduino. (This article is a companion to another Instructable I’ve written
Send sound into your Arduino. This Instructable will show you how to prepare audio so that it can be sampled and processed by an Arduino to make sound responsive projects and audio effects. (This article is a companion to another Instructable I’ve written about building an audio output circuit for an Arduino, find that here) Some
Today, I’m going to show you how to make an Arduino motor shield (driver) at a low cost. It works splendidly, its posses almost all the characteristics of the original Arduino motor shield. It’s almost considered as a clone. The original Arduino motor shield has the same motor driver chip (L298), the only difference with it,
I was wondering about on making a sequencer, a big 16 step sequencer was what I wanted to make. To it’s full extension with lots of features including single leds for each step, midi input and output, etc. Then I realised that I should start from a more basic model and then maybe tweak around to see
The device is based on a GSM/GPRS module with included GPS. Its main function is to detect and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. Its small dimensions are due to the use, for the first time, of a GSM/GPRS module integrating the GPS receiver.
Description The LM96511 is an 8-channel integrated analog front end (AFE) module for multi-channel applications, particularly medical ultrasound. Each of the 8 signal paths consists of a low noise amplifier (LNA), a digitally programmable variable gain amplifier (DVGA) and a 12-bit, 40 Mega Samples Per Second (MSPS) analog-to-digital converter (ADC) with Instant Overload Recovery (IOR).
Talking to Arduino over a serial interface is pretty trivial in Python. On Unix-like systems you can read and write to the serial device as if it were a file, but there is also a wrapper library called pySerial that works well across all operating systems. After installing pySerial, reading data from Arduino is straightforward:
This example demonstrates one techinque for calibrating sensor input. The board takes sensor readings for five seconds during the startup, and tracks the highest and lowest values it gets. These sensor readings during the first five seconds of the sketch execution define the minimum and maximum of expected values for the readings taken during the
Description The LT®3743 is a fixed frequency synchronous step-down DC/DC controller designed to drive high current LEDs. The average current mode controller will maintain inductor current regulation over a wide output voltage range of 0V to (VIN – 2V). LED dimming is achieved through analog dimming on the CTRL_L, CTRL_H and CTRL_T pins and with
