When you start tinkering with micro-controllers, one of the most important tools you will have in your toolbox is a chip programmer. There are a lot of programmers for different types of micro-controllers. So the type of programmer you have depends on the type of micro-controller you want to program. For example, 8051, PIC, AVR
This circuit, police strobe light effect using Arduino is something I just come up with, out of boredom. I mean, actually I saw a similar effect in a group and when I asked the poster for the schematic it happens that his original circuit is using 547/557 ICs. So due to the lock-down because of
Transformerless AC – Dc power supply is a type of power supply circuits that doesn’t require a transformer to step down the normally high household AC line. There are generally two types of transformerless power supply circuits. Capacitive and Resistive tranformersless power supply. Capacitive type is more efficient since its heat dissipation and power loss
Welcome! Today we are going to build an Infrared Remote Control Switch using CD4017 IC. As if you don’t know what an infrared remote control is, this is a switch that will be controlled with an infrared transmitter. Infrared remote controls (transmitters) are very common today that almost every home appliance comes with one. So
Darkness Activated Switch is a type of switch that gets activated automatically when there is darkness. In that, the switch energizes any system or circuit that is connected through it. In this tutorial, I am going to teach you how to design such a switch using the famous 555 timer IC. The basic component of
In this tutorial, I am going to teach you how to interface I2C Character LCD with Arduino UNO. A character LCD is a common type of LCD that is ideal for displaying text and number based information. What this means is that it cannot be used to display images, hence the word “Character” in the
Microcontroller is a type of integrated circuits designed to govern a specific operation in an embedded system. A typical microcontroller includes a processor, memory and input/output (I/O) peripherals on a single chip. Microcontroller sometimes referred to as Microcontrollers unit (MCU) can be found in almost every modern systems ranging from vehicles, robots, vending machines and
Sequel to our last tutorial Introduction to PIC microcontrollers, In this tutorial we are going to learn the methods of programing PIC microcontroller. If you still remembered, in the last tutorial, we learnt basically what a PIC microcontroller is and the hardware and software required in other to program a PIC microcontroller. So I will
