The circuit is based on a 16F873A microcontroller PIC.
Based on the Countdown with LCD 2x16, we have made this variant of the countdown. The countdown circuit, or the backwards counting we shall describe, shows the visualisation of the backwards counting on four 7 segment displays.
Twilight switch with 12F629 microcontroller .
On-off push button with a 12F675 microcontroller.
On-off sequence of three relays with a push button, microcontroller PIC 12F675.
Current clamp with a microcontroller.
In-out thermometer with 16F873A microcontroller.
With the already known microcontroller PIC 16F873A and the integrated circuit DS1307 we have built this calendar clock.
Based on our circuit “calendar clock with PIC 16F873A”, we have constructed a more complete calendar clock. We added an alarm and a temperature sensor.
Digital clock with pic 16F84A.
With a simple circuit and a microcontroller pic, 16F873A model, we designed this digital voltmeter in addition to any power source.
The project that we present here is a meter of volts, amps and watts, to which we have also incorporated a temperature sensor to activate a fan, or other mechanism that we want, through a relay.
