This project describes how a DC motor can be moved in forward or reverse direction using a TV or DVD remote control. The goal is to ... (IC2), motor driver L293D (IC3), PNP transistor BC557 (T1), two ...

Now as you see in the circuit diagram, we made a voltage divider circuit using LDR and 1 mega ohm resistor. The working of this circuit is just opposite to the NPN transistor switching. When there is ...

In this project, we will build a Simple Preamplifier Circuit using NPN transistor BC547. Here we have used this Preamplifier ... Below given is the Circuit diagram for Pre-amplification of AUX output ...

Two H-bridge motor ... forward or backward, or stop it, independently. Fig. 1 shows the circuit of dual motor control. The circuit is built around four-channel multiplexer CD4052 (IC1), ...

Today we are going to explain about a simple circuit which is used to switch on/off any electrical device remotely through a relay using ... BC547 NPN transistor (Q1). Get more information about this ...
