About the Project As a followup to my VCR Pong project, here is a gadget that is actually useful in the Real World! It superimposes the time of day, in “HH MM SS” format, in the bottom right-hand corner of an existing video signal. My friend Scott uses it with his home security system. In […]

In this session we will see how to interface 16×2 LCD to PIC18F4550 microcontroller which is of family PIC18F. You can get information of 16×2 LCD in the session How to Interface 16X2 LCD with 8051 Microcontroller Features of PIC18F4550: PIC18F4550 belongs to the PIC18F family; PIC18F4550 is an 8bit microcontroller and uses RISC architecture. PIC18F4550 […]

Several of our recent projects have used a 16 bit PIC24 microcontroller from Microchip.  The PIC24FJ128GC006 contains two 16-bit ADC channels which makes it useful for measuring voltages more accurately than the 10 or 12 bit ADCs you normally find on microcontrollers.  We used this microcontroller for the temperature controller on our recent Soldering Robot […]

The solar energy collection is not that easy compared to the different types of power generation system because it has the lowest capacity factor. It has 5 out of 24 hours in a day that it can generate electricity from its solar collection. The only solution to this is by optimizing the 5 hours solar […]

Common-Emitter and Common-Collector Transistor Amplifier Calculator for High-frequency Operation Analysis of the bipolar transistor amplifier at low-frequency is relatively easy, and several calculators exist online that do a good job. For high-frequency operation, there are fewer references available. For my projects, I like to build a reference spreadhseet where everything is in one place. This […]

The ATMega168 is a great general purpose 8-bit AVR microcontroller from Atmel. It has 23 GPIO pins, but sometimes (as I have found) you can run out of I/O pins as your design grows. This happened to me recently when, of the 23 GPIO pins available, 2 were taken up by an external ceramic resonator, […]

An application note from Texas Instruments, white LED driver with digital and PWM brightness control (PDF!): With a 40-V rated integrated switch FET, the TPS61160/1 is a boost converter that drives LEDs in series. The boost converter runs at 600kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use […]

The new PIC18F2550 Project Board was designed as the development platform for student projects. The board features MCU: PIC18F2550 with external xtal, ADC: one channel 0-2.5V sigma-delta converter, Linear Technology LTC2400/LTC2420, 6-channal 10-bit ADC 0-5V, Display: Two connectors for text LCD or GLCD, USB: onchip USB port with type B connector, Power supply: onboard low […]

Book Introduction: PIC Microcontrollers are present in almost every new electronic application that is released from garage door openers to the iPhone. With the proliferation of this product more and more engineers and engineers-to-be (students) need to understand how to design, develop, and build with them. Martin Bates, best-selling author, has provided a step-by-step guide […]

What is a pic microcontroller? The PIC microcontroller is a low cost ‘computers on a chip’ manufactured by Microchip. They allow electronic designers and hobbyists impart intelligence and logic to a single chip for special purpose applications and products. The PIC microcontroller programming is done using the popular software ‘Mikro C’. This powerful yet easy to […]
