TinyGo-powered bottle boat.
See the "Hull" page at assembly/hull.md for more information about putting together the hull of your Gopherboat.
- Microcontroller, such as Adafruit Metro M4 Airlift (ATSAMD51 microcontroller with onboard ESP32 WiFi)
- WiFi co-processor such as ESP32 (already onboard the Adafruit Metro M4 Airlift)
- Arduino Motor Controller
- 2 DC Motors
- 2 propellers (clockwise, 1 counterclockwise)
- Adafruit Ultimate GPS UART
- Adafruit I2C Digital Compass
See the "Wiring" page at assembly/wiring.md for more information about wiring up your Gopherboat.
This code should make the Gopherboat pivot in place, first turning in a clockwise direction, and then turning back in a counter-clockwise direction.
package main
import (
"time"
"github.com/hybridgroup/gopherboat"
)
func main() {
leftmotor := gopherboat.NewLeftMotor()
rightmotor := gopherboat.NewRightMotor()
for i := 0; i < 10; i++ {
leftmotor.Forward()
rightmotor.Backward()
time.Sleep(5 * time.Second)
leftmotor.Backward()
rightmotor.Forward()
time.Sleep(5 * time.Second)
}
leftmotor.Stop()
rightmotor.Stop()
}
- Install Go 1.15
You probably already have this. If not, go install Go 1.15 from here: https://golang.org/dl/
- Install TinyGo 0.14.1
On MacOS you can install TinyGo using Homebrew like this:
brew tap tinygo-org/tools
brew install tinygo
For more info, see the "quick install" instructions here: https://tinygo.org/getting-started/macos/#quick-install
You use the tinygo flash command to put new software on the Adafruit Metro M4 Airlift board. First plug in your computer's USB port to the Adafruit Metro M4 Airlift board's micro-USB connector.
tinygo flash -target metro-m4-airlift examples/blinky1
This should flash the "blinky" program onto your Metro M4 board. The built-in LED should start blinking every 1/2 second.
Now you are ready!
Take a look at the "Examples" directory for examples of how to use the various hardware.
