Arduino Project – Relay Shield made from Stripboard

This stripboard relay shield for Arduino allows you to control electronic devices connected to two relays from software running on your PC. Click the ‘On’ and ‘Off’ buttons in the PC application and watch the relays on the Arduino shield switch on and off.

Full project details, including circuit diagram, video and software are available on the Starting Electronics website, just click the above link.

 

Arduino Project – Temperature Shield made from Stripboard

In this tiny stripboard temperature shield Arduino project, the temperature from a MCP9700 temperature sensor is read by the Arduino and sent to a PC over a USB cable. The PC runs a program written in the Processing language that displays the current temperature and the temperature history on a graph.

Three LEDs on the shield can be programmed to switch on when the current temperature falls within certain temperature ranges.

The status of the LEDs is also shown in the Processing application window. Find the circuit diagram and parts list for the shield as well as all the software needed to build the project at the Starting Electronics website.
