Lab Overview This circuit is based on the popular 4017 counter IC and an active IR sensor commonly found in Arduino sensor kits. After a timed safe separation, the device is designed to count four violations and fire at the fifth. This can be used low on a doorway to count members of an assault […]

Lab Overview This is a simple LDR Sensor. The circuit’s Arming is based on a default 30 second timer which can be modified. Once the arming time has elapsed the circuit will take its initial light readings. The circuit will constantly check the LDR against the initial readings for a change that is greater or […]

Lab Overview This victim operated IED circuit fires a detonator when the PIR sensor is violated. The Arduino Pro Micro ignores the sensor input during the coded arm timer. Tools / Parts / Test Equipment Soldering Iron Helping Hands Solder Multimeter

Lab Overview This is a simple Active IR Device. The circuit will arm after a default thirty-second delay. The device will take a reading whether the Active IR has sensed and object or not, and hold this value. When this value changes the device will fire.

Lab Overview This is a simple Reed Switch Device. The circuit will arm after a default thirty-second delay. After arming, the Arduino will take a reading if the reed switch is opened or closed. The Arduino will constantly check for a change in the status of the Reed Switch and once a change is detected […]

Lab Overview This is a simple Ultrasonic Device. The circuit will arm after a default thirty-second delay. After arming, the Ultrasonic Sensor and the Arduino will take an initial distance reading to use as a benchmark. The sensor will then constantly check its readings against the benchmark looking for a change outside its prescribed tolerance. […]

Lab Overview 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 […]

Lab Overview The circuit is armed via an RC Timer and fired through an increase in light intensity. Tools / Parts / Test Equipment Soldering Iron Helping Hands Solder Multimeter
