Microcontrollers and Electronics, Bit by Bit
The GPS System has to be one of the most brilliant things ever invented.
~30 sattelites in orbit that can tell you where you are anywhere on the globe, with precision down to about 2 meters. Of course you and your Arduino should get in on the action! We’ll also look into plotting our data in the Google maps API.
If you need to control a lot of inputs / outputs on a MicroController, Shift registers are the way to go. In this project I’m using shift registers to build a circuit that control endless LEDS from 5 pins of a Micro controller
I’m making a LED display inspired by the old-timey neon signs with handwritten font; The LEDs will light up one by one to illuminate the sign.
In this project i used the Digispark attiny85: These tiny boards only have 6 GPIO pins so to manage a large amount of LEDS with a limited number of pins, you’ll need shift registers.
