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...

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...
