Adapter for small size PIC/AVR chip programming

This is a homemade adapter I made for programming SOIC/QFN size microchips that I use in my micro airplanes (http://maxoffsky.com/tech-blog/rc-micro-spitfire-airplane-build-log/). I had trouble connecting the chips any other way so I made my own universal adapter. This could also be used to do In-Circuit programming without removing the chip from the PCB. If you want an adapter to connect and fit any size m ...

Use a PIC Microcontroller to Control a Hobby Servo

This instructable describes how to integrate hobby servos (the kind used in RC planes, cars, etc.) into your microcontroller projects. Step 1: How Servos are Different from Regular Motors In a regular DC motor, the amount of torque the motor exerts on the shaft is proportional to the amount of current flowing through the motor. A simple way to control it is by varying the voltage across the motor; more volt ...

5 transistor PIC programmer *Schematic added to step 9!

Make your own PIC programmer for your computer's parallel port. This is a variation of David Tait's classic design. It is very reliable and there is good programming software available for free. I like IC-Prog and PICpgm programmer. Best of all, it uses just two voltage regulator and 5 transistors! *** I added a pic of the final result, and pics of my new mini-programmer with a clear top. Click the smaller ...

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 40-pin microcontroller. But I'm planning to create a version with movables protoboards  to ...

Simple 3 Resistor PIC Programmer

Micro-controllers play a very important role in electronics, as they are able to perform tasks in automation, control, image processing, among others. Their usage is immense. There are various families of micro-controllers, one of those is the Microchip’s PIC (Peripheral Interface Controller). PICs are very popular as they are relatively cheap and because of their characteristics, for example their low powe ...

Kaossilator 2 hack: hands free (part 1/2)

This is my first instructable.... ever. So here it goes. I own a Kaossilator 2 (KO2). It's fun little phrase synthesizer and simple looper. But it has this awkward issue with mic button. When you want to record something from microphone you have to hold down two buttons simultaneously. First the mic button to enable built-in microphone or external input (mic in) and second the loop recording bank button. Th ...

How to Program a PIC Microcontroller & Read an Encoder

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 of this project, your microcontroller will even be able to track the speed of ...

Low cost ICSP PIC-programmer using PIC16F648A

Galvanic from PC isolated PIC programmer The Wisp648 from www.voti.nl is an In Circuit Serial Programmer to program a flash PIC which mostly can stay in your circuit. No irritating doings like pulling the PIC out of the PCB, place it in the programmer, programming it, pull it out the programmer and place it back in the PCB, over and over again, it can stay in the circuit on your breadboard or PCB while prog ...

PICMicro Programmer with the “ElCheapo” using PIC16F84

Since I first released this circuit for a serial PICMicro programmer, I have been getting lots of feedback from people that have been building it as their first PICMicro programmer. It has been really nice to hear comments from people about their experiences building the "El Cheapo" as well as questions and comments calling for enhanced capabilities. This is the fourth update to this article with a yet agai ...
