Embedded Linux/Microcontroller circuit

This project is not to introduce Tic Tac Toe. Everyone knows this game. It is to introduce two features: bi-coloured LEDs, microcontrollers, and the skill of writing an ALGORITHM. You can use the project to learn the skills of creating...

Battery powered Pi and servo switch

This document outlines the details of several circuits designed and built for a robot. The first circuit is a voltage regulator intended to supply power to a Raspberry Pi from a 7.2V battery. While the circuit is relatively simple, it...

87C51 Selling Leads

This circuit utilizes an 87C57 microcontroller along with several peripherals to convert X-10 power-line carrier-code formats from a personal computer for use with an X-10 power-line interface in a home control system. Software details can be found in the reference....

Microcontroller Relay Driver and Interface

Many microcontroller designs typically integrate various interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs. Microcontroller systems are versatile platforms that facilitate the integration of multiple interfacing methods to interact with various peripherals and...

How to connect a pulled motor from a printer to Breadboard and control with raspberry pi

A couple of motors were salvaged from an old printer, and there is uncertainty regarding how to connect them to a breadboard and subsequently to a Raspberry Pi. A cobbler kit for the Raspberry Pi is available for this purpose....

Microcontroller and Motor Driver Circuit Board

Efforts were made to minimize the number of wire jumpers on this board, but space constraints arose due to the integration of the microcontroller and motor driver on a single board. The design would have been cleaner without the inclusion...

GSM Remote Control 2 IN and 2 OUT Part 2 Schematic

The control of the system is managed by a Microchip PIC18F46K20-I/PT microcontroller, which is programmed with firmware to oversee the activity of the GSM/GPRS module, monitor the logic conditions of two opto-isolated inputs, and send commands to two relays within...

High Resolution Digital Weigh-scale Design Using Z8 Encore! ?® Microcontrollers

The SP6691 circuit is designed to provide a high output voltage using a lower voltage boost regulator by incorporating a charge pump circuit. This configuration can convert a standard 30V boost regulator into a 60V boost regulator if necessary. Testing...

Hum Circuit

The kit employs an off-the-shelf microcontroller based on the AtMega328P-PU Arduino, along with a simplified version designed for ease of replication and modification by collaborators and students. This initiative aims to enable the fabrication of simplified microcontrollers for DIY synthetic...
