The 555 timer IC remains iconic and widely used. Let's explore its enduring appeal through simple, fully tested 555 projects.

Digital temperature controller circuit and working Fig. 2 shows circuit diagram of the digital temperature controller. The circuit is built around microcontroller PIC16F877A (IC1), precision ...

Data is converted from an internal diode temperature-sensing element to a digital format that can be directly interfaced to a PICmicro® microcontroller unit (MCU). The MCP9800 sensor offers many ...

Figure 2 shows the system block diagram of the solution. The difference amplifier uses MCP6V01 auto-zeroed op amp to amplify the thermocouple’s EMF voltage. The CV REF is an internal comparator ...

Water Temperature Controller – Block Diagram The block diagram of this simple project is shown in Fig. 1 and its circuit diagram is in Fig. 2. The project is built around water temperature sensor ...

There is a push-button above the PI gains box allowing the operator to switch between manual and automatic control. The slider allows one to manually control the fan speed. When the "Save” button is ...

Abstract: A Radiation hardened temperature controller intended to regenerate CMOS circuits has been designed using commercial off-the-shelf components. Tested with 60 Co gamma rays, it has shown a ...

Superheterodyne AM Receiver Circuit. Now, we know the basic functionality working of a Superheterodyne Receiver, let’s take a look at a typical circuit diagram of Superheterodyne Receiver. The below ...

The Equivalent of LM56 but With an External Thermistor. In Figure 5, we designed an analog version of the LT56, with the limit cycle of temperature control Tlow and Thigh, both determined by two ...
