Lesson 27 74HC595 and segment display

here in this lesson we will use 1 elegoo uno R3, 1 830 tie-points breadboard, 1 74HC595 IC, 1 gigit 7- segment display, 8 220 ohm resistors and 26 m-m jumper wires.

with the help of the given codes we were able to display the segments. it was changing so fast, we tried getting all the numbers. but we could captured only 1 3 4 and 8 as shown in the pictures

Lesson 26 Photocell

In this lesson we will use 1 elegoo uno r3, 1 830 tie points Breadboard, 8 leds, 8 220 ohm resistors, 1 1k ohm resistor, 1 74hv595 IC, 1 photoresistor and 16 m-m jumper wires.

the given code
with the help of codes we were abele to turn the leds on but we can observe that the intensity of the light has decreased from green to yellow.

Lesson 23 Thermometer

In this lesson we will use 1 elegoo uno R3, 1 LCD1602 module, 1 10k ohm resistor, 1 thermistor, 1 potentiometer, 1 830 tir points Breadboard and 18 m-m jumper wires.

With the given code the LCD displayed the temperature in celsius only but we changed some of the codes and make the LCD display the temperature in both celsius and Fahrenheit.

Lesson 22 LCD display

In the given experiment we use: 1 elegoo uno R3, 1 LCD 1602 module, 1 potentiometer (10k), 1 830 tie points Breadboard and 16 m-m jumper wires.

in the above picture we connect the elegoo with the LCD display with the help of breadboard and 16 m-m jumper wires.

we changed some of the code and displayed hello sakari! how are you? . the initial code displayed hello world.
