8 Channel Programmable Timer

8 Channel Programmable Timer

Introduction I have been using Microchip’s PIC range of microcontroller for my projects since 1993, and have done all my programming in assembler language, using the Microchip MPLab IDE. My projects ranged from simple traffic lights and flashing LEDs, to USB joystick interfaces for R/C models, and switchgear analisers used in industry. Development took many […]

R C Controlled Switch for Drones

R/C Controlled Switch for Drones

Although there are MANY good circuits available on the internet for similar projects, I had a dedicated problem to solve. Most of the circuits available switches their outputs on at mid stick position (50%). My drones all use six channels (Throttle, Aileron, Rudder, Elevator, GPS Mode, Flight Mode), thus not leaving any spare channel to

PianoPIC

PianoPIC

This little project is an example of a simple audio application using a PIC micro-controller. We decided to use the PIC18F4550 micro-controller for memory purposes. Using only digital inputs and outputs, we developed this simple piano/synthesizer with an 8 bit kind of style: Inputs from b1 to b11 are the push buttons in the circuit while

AVR Mini Board With Additional Boards

AVR Mini Board With Additional Boards

Somewhat similar to PIC 12f675 mini protoboard, but extended and with additional boards.Using attiny2313. Step 1: Scheme Let us first start with a scheme. The scheme is pretty obvious since it only connects attiny2313 with the pins and the only additional elements are resistors and capacitor for reseting the microcontroller.
