i am currently working with some power supply design and i can say using conventional pots(potentiometer)  and rotary  switch  to adjust the voltage and other stuff is quite old school. so i have decided to go for a bit high tech , actually bit digital. so here is the solution Incremental Rotary Encoder first of all i would […]

UC3844 is popular current mode controller which is commonly found on DC-to-DC converter circuits and switch mode power supplies. This motor speed controller is also based on UC3844 and it is specifically design to drive 20V – 24V DC motors. In this given configuration UC3844 produces (approx.) 50kHz to 240kHz PWM output and this range […]

The Microchip PIC16F877A has 40 pins 33 of them can be input or output. In this simple project I am going to configure this microcontroller to blink a 33 LED each LED is connected to one I/O pin. The PIC16F877A has 8 analog channels, so we have to configure all these channels as digital output. […]

What is it? The Small Weather Station is a battery-operated, wireless, weather station. I have been working on the project for almost a year now, and now I have an unshielded prototype that is partially functional. I say partially functional, because it does not have any wind/rain sensors installed, only the connections for them. So […]

Using only 2 capacitors, 3 resistors, 4 BIG seven-segment Display, 1 xtal, 2 switches ,and 1 Microcontroller PIC, you can build this Digital Led Clock main circuit. you can use common anode or common cathode display, just select the display type. Here is the pinout information:(I have attach the all diagrams of parts and 7 […]

CadSoft Eagle: Schematic Design In the course of making my Arduino Tutorial Series (don’t worry, I have more of those in the works), I got a ton of requests for a tutorial series on how to design circuit boards. Now, I’m answering those requests with my Eagle Tutorial Series! Supported by element14 & cadsoft, this […]

This project shows how to decode IR remote controls which uses Philips RC5 protocol with microchip PIC16F84A microcontroller. You can find details about RC5 on Wikipedia Related topics: Philips RC5 & LG TV Remote Control Decoder IR Remote Control Based On PIC Microcontroller The RC5  protocols can be divided into 4 parts: 1-start bit, 2-Toggle […]

This PIC16F877 microcontroller tutorial answers the question, ” How to use timer1 of PIC16F877 and how to handle its interrupts? ” Using PIC16 simulator (Proteus) you can verify this PIC timer1 code and change it according to your needs. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this […]

From time to time I get requests to make some high power switching, so I decided to design a solid-state relay that could handle a lot of different situations. The most common use for it I have is refurbishing old ceramic kilns. Since our technical life is close to the stage (both theatre and music), […]
