LCD in 4 bit mode with PIC16F877

Hello friends this post is one of the proteus tutorial series, here we are going to interface LCD in 4 bit mode with pic microcontroller. If you are confused between 8 bit mode and 4 bit mode of LCD have a look at pros and cons below. Advantages of LCD in 4 bit mode: Using […]

Why your SCR (Thyristor) is not latching?

One of our readers has asked us about thyristor (scr) not being latched properly. Here is the circuit configuration of thyristor under experiment. This test circuit is simulated in Proteus 8. Thyristor (SCR) is given a continuous gate pulse, so when a positive cycle comes the thyristor (SCR) should be triggered and the output voltage should be same […]

Counter timer VSM module in Proteus used to measure frequency of 555 timer IC

Hello friends, this is another Proteus simulation project. This is about the VSM Counter Timer module available in Proteus simulation  Software. You can see in the schematic below that a 555 timer IC is used in Astable Multivibrator mode to generate square wave of different frequencies, value of frequency can be changed by changing the value […]

What is Reed Switch?

What is Reed Switch? How does a Reed Switch work? Reed switches are very similar to relays, except a permanent magnet is used instead of a wire coil. When the magnet is far away the switch is open, but when the magnet is brought near the switch is closed. These are very inexpensive. With this device the […]

8051 PWM C Program with 50 percent duty cycle

PWM(pulse width modulation) generation guide using 8051. 8051 PWM generation What is PWM? PWM(pulse width modulation) is a technique of generating pulses(square wave) having a specific on time and off time. Main use of PWM is to control power mostly in motor speed control. PWM is also used to perform DAC(digital to analogue) operation. How […]

Traffic lights control system:Proteus Simulation

Hello readers are you looking for a simple and sober Traffic Lights control system project? Well, your search for traffic lights controlling ends here. This is a really simple technique of  traffic lights control with minimum components.  This project is a very simple and self explanatory, only two flip-flops and one and gate is used for traffic […]
