As we showed in the previous example the 7 segments display is very easy to manage and is perfect for some aplications which are not many data to display( like temperatures, voltage, currents) sometimes we can combine and display data consecutive. For that we use the model from previous example ELF-511SYGWA/S530-E2. We can see that all the anodes…

One digit BCD 7 segments display and atmega328
7 segments BCD display is very easy to manage and is perfect for some aplications with low data to display. Is made from 7 LEDs mounted in a package like in the pictures below: With this device you can display 0,1,2,3,4,5,6,7,8,9,A,b,C,d,E,F and next we will explain a modality to use the device with arduino or…
Read MoreArduino homemade shield
For this project we want to make a shield for arduino. Because for many times in our project we need to have different inputs(button sensors) and different outputs(LED, motors) we want to bring to minim space used on a breadboard and wires so we try to compact them in a pcb. Parts used in this…
Read More12 VOLTS LAMP DIMMING WITH ATMEGA 328
How many time do you want a lamp that can be adjusted in intensity??? Of course you can buy it but why not to make yourself one as you like (homemade) and have the satisfaction that you made something by yourself. Such a project is detailed below: In this case we use a halogen lamp with…
Read MoreAtmega 328-PU standalone
Because the cost of an Arduino Uno on different sites are more than 30euro you could use the Atmega on the breadboard without entire Arduino board but with some pheripherals such as: -1 oscillator 16MHz -2 capacitor of 22pF -1 button(for RESET) -10 kohms resistor -5 Vdc source(you could use different sources with a voltage regulator such…
Read MoreHow to make a homemade PCB (shield for arduino)
Sometimes in our projects we need to connect different sensors and peripherals at the same arduino board and usually this thing involve many wires and space, don’t have a solid base for the parts so, those few inconveniences are eliminated with a PCB. First of all this are the materials we will use: -one side copper…
