First tests with a servo
Today I did first servo tests.
Standard Servo (ordered by Conrad electronics, 2€ something...). The servo has 3 connections. (Black=Ground=0V, Red=+6V=V_in, Yellow=Control=Pin21).
A first test code goes like this:
#include "mbed.h" PwmOut servo(p21); int main() { servo.period_ms(20); while(1) { motor=0.03; // varying the duty-cycle wait(1); // from 0.03 to 0.11 motor=0.05; // --> corresponds to wait(1); // about a rotation of 150° motor=0.07; wait(1); motor=0.09; wait(1); motor=0.11; wait(1); motor=0.09; wait(1); motor=0.07; wait(1); motor=0.05; wait(1); } }The test was successful. :-)
