Testing and prototyping various hardware or external circuitry with an Arduino will usually involve writing a test sketch and losing the amount of time required to code, debug and upload the sketch. This can be frustrating when all you need to do is quickly flip a digital output, or send a single value down the I2C bus. Therefore we're happy to share the "MiniPirate" system by Instructables member ochâtelain.
With their MiniPirate sketch - you can send various commands to your Arduino via the serial monitor in the form of commands. These include configuring and setting digital pins, PWM levels, working with the internal EEPROM and data transmission with the I2C bus.
A very simple yet clever idea that will hopefully reduce the amount of time spent experimenting with prototypes and so on. For more information and to download the sketch, visit the MiniPirate Instructable page. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
