Based on 1.1-µm pixel technology, the AR1335 CMOS image sensor from ON Semiconductor provides 18% better sensitivity than previous-generation devices, along with increased quantum efficiency and linear well capacity to enable near-digital still-camera quality and low-light imaging on smart-phone cameras. The sensor’s pixel and color filter processing increase sensitivity, allowing more light to be captured […]

In this article you will learn, Digital Thermometer using pic microcontroller and MCP9700: In this tutorial, we are making a Digital Thermometer using PIC microcontroller and LM35 Temperature Sensor. In this project, we will sense the temperature using LM35 and display it on 16×2 LCD. LM35 Temperature Sensor is accurate and cheaper and doesn’t require any […]

In most cases, you measure current by converting it into a proportional voltage and then measuring the voltage. Figure 1 shows two typical methods of making the conversion. In one method, you insert a probing resistor, RP, in series with the current path and use differential amplifier IC1 to measure the resulting voltage drop (Figure […]

Here you will find complete construction details including circuit diagrams, PCB layouts and PIC firmware (and the source code). The code was written in Proton PIC BASIC but the good news is that there is now a free version of this compiler available for download; AMICUS18. ** UPDATED 17th Aug 2013 ** There was a […]

With a package outline of just 1.2 x 2mm the Micrel MIC95410 is able to switch loads of 7A in the voltage range of 0.5 to 5.5 V. The switch provides high-side switching and the company anticipates it will find applications in the field of computing generally and in ultra-dense embedded computer boards where high-current, […]

This is microcontroller led flasher circuit using PIC16F627A as first PIC microcontroller learning of mine son. it is basic for really beginner. Important issue,we have to make The PIC micro controller is easier. Children 8 years old, he does not understand the computer language at all. My friends say that children should not play computer. […]

In our modern era, digital logic has become the core of all the electronics circuits either in the form of an FPGA, microcontroller, microprocessor, or discreet logic. Digital systems use many components that must be interconnected to perform the required functions.  The vital element for proper operation of such a digital system is a CLOCK […]

Build a simple real-time controller with PIC16F84 running at low power X-tal 32,768Hz. Daily scheduler for 6-channel resided in 64-byte EEPROM can easily be preprogrammed  using Nigel PicProg. RTC2.C provides user programmable set current time without the need of recompilation. Fixed bug on minute conversion! Introduction The F84 MRTC was my second design of a […]

  Here is 0 to 99 minutes relay timer using PIC16F628 microcontroller and 16 character LCD display. The microcontroller is PIC16F628A running at 4.0 MHz clock using an external crystal. An HD44780 based 16×2 character LCD is the main display unit of the project where you can watch and set the timer duration using tact […]

Hi group, A while a go I shared my design for a small electronic load that was limited to dc operation only. I am in the process of design and construction of a dynamic load. The dynamic load steps the load current so that the transient response of the power supply being tested can be […]
