Connecting an ACS (Allegro Current Sensor) with an Arduino allows you to measure AC or DC currents in your electrical circuits. ACS sensors are commonly used for monitoring currents in various applications, including power monitoring, load detection, and more. Here’s a step-by-step guide on how to connect and use an ACS current sensor with an Arduino:

Components Needed:

1. Arduino board (e.g., Arduino Uno or Arduino Nano)
2. ACS current sensor module (e.g., ACS712)
3. Load or circuit you want to measure current from
4. Breadboard and jumper wires

ACS Current Sensor Module (ACS712) Pinout:

The ACS712 current sensor module typically has 5 pins:

• VCC: Power supply (typically +5V)
• OUT: Analog output signal (connect to an analog input pin on the Arduino)
• GND: Ground (connect to Arduino GND)
• VCC: Power supply (typically +5V)
• VCC: Power
