Arduino Code For Brushed ESC :
// Brushed Electronic Speed Control | Fırçalı Elektronik Hız Kontrol (ESC)
void setup() {
pinMode(11, INPUT); // Receiver Throttle Signal Input| Alıcı Gaz Kanalı Sinyal Girişi
pinMode(3, OUTPUT); // Mosfet Gate Output Pin | Mosfet Gate Çıkış Pini
}
void loop() {
analogWrite(3, map(pulseIn(11, HIGH), 1000, 2000, 0, 255)); // map received value to arduino pwm range (for normal radio control system) | Normal kumanda sistemleri için PWM aralığı harita değerleri
// analogWrite(3, map(pulseIn(11, HIGH), 1095, 2000, 0, 255)); // map received value to arduino pwm range (for hand made arduino radio control system) | Arduino ile el yapımı kumanda sistemleri için PWM aralığı harita değerleri
delay(15);
}
Note: The first value in the map command, “1000”, determines the signal start value. This may be different for some transmitters. You may need to try between 800 and 1150 values.
The diode value in the motor connection section is related to the current power drawn by the motor. For small low-power motors, 1A is sufficient. But for much larger motors, 5A may be required.
The function of the diode: When the power to the motor is cut off, the energy accumulated in the coil is transmitted back to the circuit. This can damage the circuit. The coil prevents reverse voltage and protects the circuit.
