+# Proportional-Integral-Derivative
+
+PID `(Proportional-Integral-Derivative)` is a type of control algorithm commonly used in engineering and industrial applications to regulate a system's output based on its error or deviation from a desired setpoint value. The PID controller works by continuously measuring the system's output and comparing it to the setpoint value. It then uses a combination of proportional, integral, and derivative terms to adjust the system's input in order to minimize the error and bring the system closer to the desired setpoint.
+
+The proportional term provides a direct relationship between the system's error and the controller's output. The integral term integrates the system's error over time to provide a corrective input that accounts for long-term changes. The derivative term provides a rate of change measurement to account for the system's responsiveness to changes.
+
+Together, these three terms allow the PID controller to respond quickly to changes in the system's output while also providing stability and minimizing overshoot. PID controllers are commonly used in a variety of applications, such as temperature control in industrial processes, motion control in robotics, and speed control in motors.
+
+![](introduction-to-pid-damped-controller.webp)
+
+An example algorithm could look like
+
+```typescript
+function PIDController(Kp: number, Ki: number, Kd: number, setpoint: number, dt: number) {
+  let error = 0;
+  let integral = 0;
+  let derivative = 0;
+  let lastError = 0;
+
+  return function update(input: number) {
+    error = setpoint - input;
+    integral += error * dt;
+    derivative = (error - lastError) / dt;
+    lastError = error;
+
+    return Kp * error + Ki * integral + Kd * derivative;
+  };
+}
+
+```

+# I²C
+
+The Inter-Integrated Circuit (I2C) bus is a communication protocol used to transfer data between integrated circuits on a circuit board. It was developed by Philips Semiconductors (now NXP Semiconductors) in the 1980s as a way to connect peripheral devices to a microcontroller.
+
+I2C uses a two-wire serial interface consisting of a clock signal `(SCL)` and a data signal `(SDA)`. Multiple devices can be connected to the same bus, with each device having a unique address. The bus is controlled by a master device, which initiates all communication with the slave devices.
+
+Communication on the I2C bus is initiated by the master device sending a start condition, followed by the slave address and the read/write bit. The slave device then acknowledges receipt of the address, and the master device can then send or receive data to or from the slave device.
+
+One advantage of the I2C bus is that it uses only two wires, making it a simple and efficient way to connect multiple devices on a circuit board. Additionally, the protocol supports multiple data transfer speeds, allowing for flexibility in device communication.

+    A(Master Device) -- SCL --> B(I2C Bus)

+    B -- SCL --> D(Slave Device 2)
