🤖🔥 Let’s start with a simple robotic arm or leg movement using servo motors and an ATtiny85.

🔹 Step 1: Components Needed

✅ Microcontroller – ATtiny85
✅ Servo Motor – SG90 (small) or MG996R (stronger)
✅ Power Supply – 5V (for servos)
✅ Potentiometer (optional) – For manual control
✅ Jumper Wires & Breadboard

🔹 Step 2: Circuit Connection

🔹 Step 3: Code for Basic Servo Control

If you’re using ATtiny85, use the Servo8Bit library (because ATtiny has limited PWM).

🔹 Code for ATtiny85 (Basic Servo Movement)

#include <Servo8Bit.h>

Servo8Bit myServo;  // Create servo object

void setup() {
    myServo.attach(0);  // Connects to PB0 (Pin 5 on ATtiny85)
}

void loop() {
    myServo.write(0);    // Move to 0° position
    delay(1000);         // Wait 1 sec
    myServo.write(90);   // Move to 90° position
    delay(1000);         
    myServo.write(180);  // Move to 180° position
    delay(1000);         
}

🔹 Step 4: Upload Code

📌 Use Arduino as ISP to burn the code

🔹 What’s Next?

✅ Once you get the servo moving, we can:

• Add a second servo for more movement
• Use a potentiometer for manual control
• Start designing a simple robotic leg or arm
