The LM324 Quad Op Amp Line Follower Robot with Pulse Width Modulation

The LM324 Quad Op-Amp Line Follower Robot with Pulse Width Modulation

Designing a simple and yet functional Line Follower Robot (LFR) is always a fascinating and challenging subject to be learned, the LFR actually could be implemented in many ways start from a simple two transistors to a sophisticated PID (Proportional, Integrate and Differential) which take advantage of the programmable feature of microcontroller to calculate the […]

Mid Range PICMicros

Bit-Banging Serial Interfaces for the Low-End and Mid-Range PICMicros using PIC16F84

When I designed the “YAP” for the “YAP” PICMicro programmer presented in “Programming and Customizing the PIC Microcontroller”, I felt that the serial interface provided in “execution mode” of the programmer would be very useful for people developing their own software. With this interface, the user could input new values into the PICMicro application or […]

The Line Follower Robot with Texas Instruments 16 Bit MSP430G2231 Microcontroller

The Line Follower Robot with Texas Instruments 16-Bit MSP430G2231 Microcontroller

When Texas Instruments (TI) introduced their new value line 16-bit microcontroller complete with the programmer and development board named MSP430 Value Line LaunchPad in the mid of 2010 for only USD 4.30 include the shipping cost, this make it as the cheapest programmer and development board platform that you could ever find in the market. […]

Prototype Openbench Logic Sniffer logic analyzer

Prototype: Openbench Logic Sniffer logic analyzer using pic microcontoller

Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. Download the source and design files from the Gadget Factory project page. This project started in the comments on a post. Initial circuit design, PCB layout, development, and testing continued in the […]

Logic Probe Plus

Logic Probe Plus using PIC12F683

This project is based on a probe logic states, capable of measuring levels from TTL (5v) to state levels of PLC’s (24v). For this we have employed the use of the PIC 12F683 microcontroller, which by its nature is capable of operating at low voltages, in this case 3vcc, besides having analog inputs and internal […]

PIC Based Message wand

PIC Based Message wand

The project uses flashing LEDs to present shot message in the air by swinging a wand around above the head. A perfboard is used to construct the circuit that is powered by 2 coin cells type CR2016. The power fluctuations from excessive load on the coin cells can be prevented using the electrolytic capacitor. A […]

H Bridge Microchip PIC Microcontroller PWM Motor Controller

H-Bridge Microchip PIC Microcontroller PWM Motor Controller

One of the advantages using the Microchip PIC microcontroller Pulse Width Modulation or PWM for short is; this PWM peripheral circuit is designed to control the DC motor using the full bridge mode PWM feature. The PWM peripheral works by supplying the correct signal to the H-Bridge DC motor circuit such as speed controlling and […]

LEDactus

LEDactus using PIC18F1320 Microcontroller

The LEDactus is my version of a dry climate niche dweller like a cactus. LEDactus is immobile and attempts to survive by creating a pleasant display. This is of course in the hopes that passersby will be so entranced that they will build the LEDactus’ progeny. Initial generations create a simple but pleasing display. Later […]
