“Project: Create a graphic servo tester that lets you test your servos. I had some servos that I needed to test. I had to see if they worked, and needed to see what the limits were for clockwise and counterclockwise …
“The circuit implements a 6-Bit Digital to Analog Converter (DAC) using a 8-4-2-1 Resistor combination. Arduino Uno Output pins 13 to 9 form the 6-Bits PB5 to PB0.”
“LCD is a preferred medium of interface when dealing with embedded systems. It can display both numbers and characters. Further, the graphical LCD (GLCD) is even better, as it can display texts, plot curves, display pictures. In the present context …
“The circuit below is used to connect a relay to the arduino UNO to control high voltage electronics.”
“Hello, in this project I want to show you how to build a PWM generator with a Attiny processor. It is very easy to build and a nice project for starters as also for professionals. You will need some electronic …
“This project is used to switch the electrical appliances remotely using TV remote. It uses philips RC5 protocol based remote. The micro controller used is of Atmel i.e. at89c2051 of 8051 type. I have used triacs instead of relays …
“Since I got my bike, I had always wanted to do something interesting bike related. Riding a bike at night is a bit dangerous, so I decided to build a DIY bike rear light to keep me safe.! Most bike …
“Microcontrollers such as Arduinos are a great way to control your custom electronics projects. Unfortunately the digital pins have a max output of 40mA, and this isnt enough to power most motors. This is where a motor controller shield can …
“Here we are going to interface a MSP430 Launchpad with a RS485 transceiver chip like MAX485 and communicate with an x86 PC. Serial(TTL) or RS232 protocol is fine if you are planning to communicate over short distances of a …
“To start with, ROMs come in a few different varieties. The most well known are EPROMs. These are ICs with a quartz window on the top, through which you can see the storage array on the silicon. This window is …
