52- Accelerometer 328P with LDR


This circuit is designed to be used in a Category A Scenario for Hand Entry training. This circuit uses two microcontrollers. U1 is the brain of the device, while U3 is used as an accelerometer. The circuit operates as an anti-disturbance device and has a secondary firing switch in the form of an LDR. The circuit can be used in a multitude of hand entry training scenarios.
Note: Hand entry is the process of rendering safe an improvised explosive device by direct contact with the device and/or its components.
