Working of the Basic 5V Relay Circuit. In the above circuit, 5V relay is powered by a 9V battery. An ON/OFF switch is added for the switching purpose of the relay. At the initial condition when switch ...

Relays are frequently used in our electronics applications specially when we need to drive high loads from microcontroller circuits. So in this DIY project, we make a 4-Channel Relay Driver Circuit to ...

I simulated the circuit in TINA-TI, applied a sinusoidal input signal, and plotted input-output waveforms. Finally, I compared the theoretical and simulated gain values. Problem 2: Relay Module Design ...

In this assignment, I designed and analyzed two circuits: a BJT amplifier and a relay module. Problem 1: BJT Amplifier Design I determined the assigned BJT BC548 based on my student ID. I referred to ...
