0-10V control for RC servos

This project uses only a few of the instructions that come with PicBasic, but serves to show how easy PicBasic really is. It also shows how PicBasic strongly resembles programming the BASIC Stamp. Here we are using the serin...

A switch that is controlled by its ambient temperature operates without human intervention, except during the assembly of the electronic thermostat. This thermally controlled switch has numerous practical applications. For instance, if the internal temperature of a computer rises...

This circuit illustrates a precision digital timing control system. The controller includes a crystal oscillator circuit, a divider, a counting circuit, and monostable flip-flops. The crystal oscillator circuit features a series of 14 binary counters/dividers, a watch crystal operating...

The HID ballast circuit consists of a buck stage for regulating lamp current and power, a full-bridge output stage that generates a low-frequency (200Hz) AC square-wave voltage and current to drive the lamp, and an ignition circuit that produces...

These circuits allow an ON-ON type DPDT toggle switch to control a twin coil switch machine motor. The handle of the switch can then be used to indicate the route selected. The circuits are also able to control LEDs...

Stepper motors consist of a permanent magnet rotating shaft, known as the rotor, and electromagnets on the stationary part that surrounds the motor, referred to as the stator. One complete rotation of a stepper motor is illustrated. At position...
