Breathalyzer is a device for estimating blood alcohol content (BAC) from a breath sample. Based on this information, you may drive or not. Alinke has made simple Breathalyzer that can communicate with Android Phone.The main component of this project is the IOIO board which enables an Android phone to receive data from Seeed Grove alcohol sensors. The project uses IOIO because it provides mature and easiest method interfacing Android phone with 'outside world' and able to communicate over Bluetooth than as opposed to a hardwired USB cable which ADK (API ...

If you want to connect your sensor using Android phone, then IOIO board could be the simple solution for it. The IOIO (pronounced "yo-yo"), a PIC-based board designed to work with Android device (OS versions 1.5 and greater). The board provides robust connectivity to an Android device via a USB connection and is fully controllable from within an Android application using a simple and intuitive Java API - no embedded programming or external programmer will ever be needed.The IOIO board contains a single PIC MCU that acts as a USB ...

The project built to solve product tracking problem for the Sand Silo, which holds 50,000 Pounds of Sand. It uses BASIC Stamp board for easy development, 4 Line LCD Display, and DS1302 IC Timer. The program will display elapsed timer to LCD - how much sand was left in the Silo at any point in time. It also track the sand used on each job to more accurately keep track of the material cost.One of the issues encountered was the calibration of the Sand Hopper, which had been incorrectly set ...

This automatic liquid filler machine uses pneumatic system operation to measure liquids like paint. It uses BASIC Stamp to control a Load Cell based digital weigh scale indicator with 2 set points.When the user places a container on the weigh-pan, a valve opens and product begins to flow. When the container has reached its target weight, the valve closes. In order to decrease the error of product remaining in-flight, sampling speed is fast (about 38 reading /sec).Features: 5 digit display 00.000 Kg, 16 buttons keypad, AC load cell excitation, Zero ...
