Product Description The BLEE Multi-Coin Acceptor is a high-performance, programmable coin validator designed for automated self-service systems. Unlike single-coin acceptors that only recognize one specific token, this CPU-driven module can be trained to recognize up to six different denominations (e.g., ₹1, ₹2, ₹5, ₹10, and two custom tokens). It utilizes advanced electromagnetic mass and diameter sensors to verify the authenticity of each coin, effectively rejecting slugs, counterfeits, and foreign currency. This is a critical component for the Robogears team when building coin-operated water dispensers, laundry machines, or gaming kiosks.
Key Highlights
Intelligent CPU Learning: No computer is required for setup; the module features a learning mode where you insert sample coins to "train" the internal memory.
Anti-Cheat Technology: Equipped with software protection to prevent "stringing" (pulling a coin back out) and electronic interference (fishing) that common cheap acceptors might fall victim to.
Adjustable Pulse Output: You can configure the pulse width (Fast, Medium, Slow) to ensure compatibility with different microcontrollers like Arduino, Raspberry Pi, or dedicated game boards.
Multi-Parameter Verification: Analyzes the coin's material, diameter, and thickness simultaneously for a high accuracy rate.
Digital Display: Features a built-in LED display on the side to assist during the programming phase, showing the number of pulses and coin types.

Installation Tip from Robogears To use this with a 5V microcontroller (like an Arduino), remember that the module runs on 12V. While the pulse signal (White wire) is usually an open-collector output, we recommend using an optocoupler or a voltage divider to ensure you don't accidentally send 12V into your microcontroller's digital pin. When training the device, use at least 20 samples of each coin to build a reliable "profile" in the CPU memory. If the device starts rejecting valid coins, use a can of compressed air to clean the internal optical sensors from dust buildup.
