Quotation Machine using the CheeseBoard

Posted by Matthew Little on

Setting yourself a small challenge in the form of an interesting project is a great way of learning - even if it involves a fair bit of failing! I set myself a weekend challenge of using our CheeseBoard ESP8266 development board to obtain and display some data from a website using a wifi connection. My original challenge was to show real time data about the electricity supply mix within the UK. As I looked into this problem I realised that it was far too complex for me to start with. So I reduced the challenge to display some data from...

Bat Listener, Arduino and display!

Posted by Matthew Little on

Following on from our previous post on connecting the Bat Listener kit to and Arduino, here we show you how to add a small LCD screen to display frequency data and a 'sonograph'. Hopefully you have the Bat listener connected to the Arduino and are reading data onto the serial port. The next step is to add a small display so we can have a portable display of the most interesting data. What is a 'sonograph'? A sonograph (sometimes called a 'sonogram') is a graph of frequency against time. Displaying the frequency measured by the Bat Listener against time allows...
