Race Start Controller

Scalextric Sport Race Start Controller using PIC16F627A

Overview I developed this after my nephews got a Scalextric Sport slot car racing set for Christmas.  The set included a lap timer and counter but one thing that was missing was a way to start a race.  Having someone say “3-2-1-Go” wasn’t really doing the job, especially as it was easy to go just […]

Development system for PIC and AVR microcontrollers

Development system for PIC and AVR microcontrollers

After testing many systems development for PIC and AVR microcontrollers, none satisfy me. So I created this system with breadboard that has satisfied me. Step 1: More space free In this development system, I put two protoboards turned 180 degrees from each other. The space that is left to just enough space to insert a […]

Breakout board for 18 pin PIC16F series microcontrollers Schematic

Breakout board for 18-pin PIC16F series microcontrollers

The 18-pin microcontrollers from PIC16F series have always been my favorite processors. They are small in size (so occupies less area on the circuit board), and are very easy to use. Besides they are capable enough to do most projects that don’t require a large amount of computational capability. I have used PIC16F628A and PIC16F1827 […]

Skateboard with PIC microcontroller and LEDs Schemetic

Skateboard with PIC microcontroller and LEDs

What do you get when an Electrical Engineer builds a Skateboard from scratch for a 13 year old’s Christmas present? You get a skateboard with eight white LEDs (headlights), eight red LEDs (tailights) all controlled via PIC microntroller! And I might add, one very happy 13 year old, well as happy as a 13 year […]

IR Digital Thermostat for FAN Schematic

IR Digital Thermostat for FAN

Introduction  This circuit measures temperature in Celsius scale and displays it on an alphanumeric LCD screen When temperature rise to 40 C an alarm is activated and at the same time a relay is also activated which drives a fan to keep the temperature at a level. Another feature of this circuit is that you […]

Tutorial Building cool projects with MCUs Part 3 Schematic

Tutorial: Building cool projects with MCUs (Part 3)

Tutorial: Building cool projects with MCUs (Part 3) As we proceed onto the third portion of this microcontroller tutorial, let’s first revisit what we have accomplished thus far. In Part 1, we defined what a microcontroller actually was. I wanted to get everybody on-board (no pun intended) for this, so I started from scratch. Feel free to […]

COFFEE POWER MANAGER

COFFEE POWER MANAGER using PIC16F628

Introduction The problem was this…at Redeeming Grace Church we were meeting in a public school prior to moving in to our permanent facility. Each Sunday morning we would bring in three large percolating coffee pots to brew regular, decaf, and hot water for the mid-service break time. Each pot drew 9 amps. Because the average […]

Smart doorbell System Schematic

Smart doorbell System

Introduction On request I have built a microcontroller-based doorbell system which is being used in an industrial environment. This is the basic function: When you push the bell-button, a horn will sound for about 10 seconds. At the same time a light, which keeps burning until someone pushes a reset-button, will be activated. The system […]
