Electronic Projects redrok Electronic Projects mostly associated with solar power. With these requirements in mind, and some others, I decided on a variation of National Semiconductors "Micro Wire"(TM). Programmable digital timer switch using a PIC Microcontroller Embedded Lab Digital timer switches are used to control the operation of electrical devices based on a programmed schedule. This project describes a programmable digital timer based on the PIC16F628A microcontroller that can be programmed to schedule the on and off operation of an electrical appliance. The appliance is controlled through a relay switch. Testing Electronic ponents Welcome to talkingelectronics FIXING A MULTIMETER A multimeter can get "broken" "damaged" and go "faulty." I don't know why, but eventually they stop working. It can be something simple like a flat battery, corroded battery contacts, broken switch or something complex, like the circuitry failing. Voltage Controlled AC Light Dimmer PCB Heaven I have a really good zero cross detection circuit posted in the dimmer theory page.This circuit will generate a clean rectangular positive pulse whenever the waveform crosses the zero point. SparkFun Inventor's Kit Experiment Guide v4.0 learn.sparkfun Learn at SparkFun Electronics The primary difference between the two kits is the microcontroller included in the kit. The SparkFun Inventor's Kit includes a SparkFun RedBoard, while the SparkFun Inventor's Kit for Arduino Uno includes an Arduino Uno R3.At the heart of each is the ATmega328p microcontroller, giving both the same functionality underneath the hood.
