Ben Heck’s Mini Pinball kit: Selecting a microcontroller
As the development of the Mini Pinball kit progresses, Ben and Felix split their focus between different areas of the build. Ben is finalizing the design of the flippers and how they’re controlled, while solenoids are being used to give the power required to blast the metal ball up the table. Thanks to a technique called pulse-width modulation (PWM) from the Arduino software, we can make sure the device isn’t powered all the time. Felix isn’t having an easy go of it with the Teensy 3.6: After switching out the I2S audio circuit, so he’s now using a digital-to-analogue Converter (DAC), and the SD card Arduino libraries meanwhile aren’t making the right noises.
