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 […]

Introduction Ā 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 (PartĀ 3) As we proceed onto the third portion of this microcontroller tutorial, letās first revisit what we have accomplished thus far. In Part 1,Ā 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

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

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

The PIC sonar range finder works by transmitting a short pulse of sound at a frequency inaudible to the ear (ultrasonic sound or ultrasound). Afterwards the microcontroller listens for an echo. The time from transmission to echo reception lets you calculate the distance from the object. PIC Sonar Specification Range ~5cm – 300cm Accuracy +/-3cm

Comments: All resistors are 1/4W.The circuit is powered by 9…15V DC or AC. When In Circuit Programming (ISP) connectors are used, is possible the programmer to be powered from targetās power source. Diodes D2 and D6 protect the regulator LM7805, when targetās power is used. ‘ XTAL JUMP ‘ is used to cut XTAL when

We are now in the fourth part of the microcontroller tutorial. We have a microcontroller circuit diagram ready. Itās time to make a circuit board. I love this part. This is the āmagicalā step that takes the idea we started with and turns it into something real. But letās recap. So far we have learned:
