This module is based upon the basic setup circuit for PIC16F688 that I have described in one of my PIC lessons, Getting ready for the first lab. I thought of soldering this circuit on a general purpose ptototyping board and use male headers to access the power supply pins and I/O ports of the PIC16F688 microcontroller. […]
Introduction: From electronic toys & games to microwave ovens, microcontrollers can be found just about anywhere these days! But how can we make these small computers work for our own electronics projects? That’s where this tutorial comes in – with detailed instructions showing you what to do every step of the way. At the end […]
Description Today’s lab session is about binary counting LEDs. The binary 1 and 0 will be represented by turning LEDs on and off. You will make a 4-bit binary counter (using 4 LEDs) that counts from 0 to 15 (0000-1111 binary). The four LEDs are connected to RC0 through RC3 port pins of PIC16F688 with […]
For those are not into electronics, you must know that an oscilloscope has basically only one timebase to move the spot horizontally from left to right with the same intensity. The vertical deviation is function to the input voltage. You understand immediately that you can’t directly display 7 segment digits, because you can’t move the […]
Background My friend Arthur, in his lifelong quest for circuits that don’t really do anything useful, but are really neat nonetheless, built a really neat Lissajous pattern generator. This Lissajous pattern is not your traditional circle, oval, or figure-8, it is a circle with varying amplitude, in a pattern that makes it look like a […]
I’ve been spending a lot of time thinking about op amps and comparators lately. One of the common uses of an op amp is as a “unity gain” buffer, meaning that the output voltage is as close as possible to being the same as the input voltage. At a glance this might seem like a […]
Capacitance Probe A simple probe can be made using insulated wire. The insulation is then the dielectric of an cylindrical capacitor with the inner conductor as one plate and the water as the other. The probe is not suitable for distilled or very pure water because it is not conductive enough. It works well even […]
Mork is adaptation of Nanu nanu Microchip PIC ICSP for the STM32 based vcc-gnd or Maple mini. Both STM32 boards are inexpensive boards which don’t cost much more than the Nano 3.0 yet they are far more powerful. One complication though for the vcc-gnd, is that it comes with a serial boot loader which is […]
The BOLT microcontroller board utilizes the Microchip 18F2550 with built in USB capabilities. Utilizing a 2k ‘boot loader’ this leaves a great deal of flash RAM for C programming using MPLAB and the C18 compiler. The BOLT board comes in two versions. LITE which has the 18F2550, 8 LEDs for PORTB, four switches and a […]
