12v Vacuum Pump Demo

Need to create a vacuum, then use this easy to use pump :

http://proto-pic.co.uk/12v-vacuum-pump/

Needing a very modest 12V at 1 Amp Supply this pump can be included in many projects,
with a small 40mm x 65mm x 90mm footprint, it can fit easily into small enclosures if required.

In this short video Roy shows you how to use the Seeed Studio 125KHz RFID UART Module.

Example Arduino sketch and VB app

Roys Techno Babble #2 Interfacing the TPA81 with an Arduino and sample VB app

Roy shows how to interface the TPA81 with an arduino and how to visualise the readings in a VB App.

Example Arduino Code and VB App

Application Example of the 50kg Load Sensor

Here can see a short video which shows how we hooked up 50kg Load Sensors PPSEN-10245

Here is an example schematic that we put together using the Texas Instruments INA114 Instrumentation Amplifier which will connect to an ADC Input

A simple example sketch using 2 Digital inputs and the Data Logging Shield

This example was for a simple logger which polls 2 input buttons and records a message including the date/time. Although fairly simple this example may benefit anyone who is looking to get a head start on using our Adafruit Data Logging Shield.

The Example can be found on our Forum here.

Getting the Arduino Pro Mini 328 – 5V/16MHz to work with the Arduino Serial USB Board.

One of our customers was having problems getting his sketches uploaded to his new Arduino Pro Mini 328 using the Arduino Serial USB Board.
According to info found on the Arduino website it tells you to hit the Reset button on the board just before pressing the Upload Sketch button in the IDE.
Now I don’t know about you but this worked for me about 1% of the time and was very frustrating.
OK so let’s get the Serial USB Board to Reset the Arduino Pro Mini for us by wiring the RTS pin of the Serial board to the Reset pin on the Pro Mini.

This works nicely everytime you want to do an upload so here is a video of our setup……
