Belajar Arduino Driver Monster Moto shield
Hallo Sobat Arduino Indonesia,yuk belajar arduino lagi :). oke langsung saja ini karena di W/S Sekolah Robot Indonesia ada shield Driver Monster Moto. yuk kita program untuk menggerakkan motor DC.
oh ya kalau yang beli baru kadang-kadang ada yang harus nyolder dulu, gampang kok sobat. bisa cek di video dibawah ini ya.
Yang dibutuhkan pada percobaan kali ini,
Driver Shield Monster Moto ini mempunyai pin yang digunakan adalah pin 7,4,8,9,5,6,2,3.
untuk konfigurasi pin bisa dilihat pada coding program berikut ini

Please improve upon it! Let me know how you've made it better.
This is really simple example code to get you some basic
functionality with the MonsterMoto Shield. The MonsterMote uses
two VNH2SP30 high-current full-bridge motor drivers.
Use the motorGo(uint8_t motor, uint8_t direct, uint8_t pwm)
function to get motors going in either CW, CCW, BRAKEVCC, or
BRAKEGND. Use motorOff(int motor) to turn a specific motor off.
The motor variable in each function should be either a 0 or a 1.
pwm in the motorGo function should be a value between 0 and 255.

0: Brake to VCC
1: Clockwise
2: CounterClockwise
3: Brake to GND
pwm: should be a value between ? and 1023, higher the number, the faster
it'll go
