Killer Power Electronic Circuit

The goal of this project is to install a hardware Trojan horse on the designed circuit produce the finished product.

=Problem Definition= We first found a circuit that USES two identical photoresistors and relays to determine the direction of movement.Familiar with and understand its specific working principle.During the measurement, when the object moves from the photosensitive resistor RG2 to the direction of RG1, the RG2 is firstly blocked by the object, which causes the RG2 resistance value to increase and the bridge balance is destroyed. The bridge output UAV is less than 0.Compound pipe Q1 on, Q2 up.Relay K1 coil has current flow, the relay is often open contact suction.By the same principle, according to the working order of the relays, we can judge the direction of the object's movement. There are a few caveats in this project 1. The normally open contact control circuit of the relay in the circuit is not drawn. When it is actually made, the led can be controlled. 2. the photosensitive resistor should be selected with the same model and the same batch of the same manufacturer to minimize device differences. 3. The circuit needs to be debugged before it can start working

Background
The project requires the addition of a Trojan horse to a familiar circuit.Make a circuit to realize self destruction is the premise of the circuit has a very thorough understanding of the permanent self-destruct or transient circuit self-destruct will be applied in many aspects of our life, whether it is necessary measures to protect the safety of property information electronic science and technology company, or entertainment aspects involved, the design of the circuit self-destruct has broad application prospects.
