#5 Graphic Monitor Project with PicoBricks

When we look at the electronic items around us, you realize that they have many replaceable features and they are designed by engineers to be most useful to the user. Such as lighting systems, cooking systems, sound systems, cleaning systems. The way it works, the amount, the method, etc., by many system users. features can be programmed to change.

In robotic projects, in the processes of changing the sound level, changing the motor speed, changing the brightness of the light, the electrical voltage is sent in a way that creates a lower or higher effect. By decreasing the frequency of the electrical signal to the component, it can be operated at a lower level, and by increasing the frequency of the outgoing electrical signals, it can be operated at a higher level.

In systems without a screen, real-time graphic monitors are used to monitor some sensors and variables involved in the operation of the system. Graphic monitors make it very easy to detect the fault.

Details and Algorithm

In this project, we will prepare a project in which we increase or decrease the brightness of the red LED with a potentiometer. In addition, we will simultaneously monitor the electrical change occurring during this process on the Microblocks graphic monitor. When the picobricks starts, the potentiometer value will be read continuously and the brightness value of the LED will be adjusted. Applications in which the effect of the electrical signal is reduced by changing the frequency is called PWM. We will send the analog values ​​we read from the potentiometer as PWM signals to the red LED and we will be able to adjust the illumination intensity.

#4 Thermometer Project with PicoBricks

Sensors are the sense organs of electronic systems. We use our skin to feel, our eyes to see, our ears to hear, our tongue to taste, and our nose to smell. There are already many sense organs (sensors) in the picobrix. Also, new ones can be added. You can interact with the environment using humidity, temperature, light and many more sensors. Picobricks can measure the ambient temperature without the need for any other environmental component.

Ambient temperature is used in greenhouses, incubators, in environments used for the transport of drugs, briefly in situations where the temperature change must be constantly monitored. If you are going to do an operation on temperature change in your projects, you should know how to measure the ambient temperature. In this project, you will prepare a thermometer with Picobricks that will display the ambient temperature on the OLED screen.

Details and Algorithm

Picobricks has a DHT11 module. This module can sense the temperature and humidity in the environment and send data to the microcontroller. In this project, we will write the necessary codes to print the temperature values ​​measured by the DHT11 temperature and humidity sensor on the OLED screen.

3 autonomous lighting project with picobricksCategoriesLed Raspberry Pi Pico

#3 Autonomous Lighting Project with PicoBricks

It is called the state of being autonomous when electronic systems make a decision based on the data they collect and perform the given task automatically. The components that enable electronic systems to collect data from their environment are called sensors. Many data such as the level of light in the environment, how many degrees the air temperature is, how many lt/min water flow rate, how loud the sound is, are collected by the sensors and transmitted to PicoBricks as electrical signals, that is data. There are many sensors in Picobricks. Knowing how to get data from sensors and how to interpret and use that data will improve project ideas like reading a book improves vocabulary. 

In this project, with PicoBricks, we will enable the LED to turn on when the amount of light decreases in order to understand the working systems of the systems where the lighting is turned on automatically when it gets dark.

Details and Algorithm

Sensors are electronic components that detect data in external environments and send data to microcontrollers. The LDR sensor also detects the amount of light in the environment and sends analog values. In our project, we will first check the incoming data when the environment is light and dark by reading the LDR sensor values, then we will set a limit according to these data, and if the amount of light is below this limit, we will turn off the RGB LED of Picobricks, if not, we will turn off the LED.

Project Proposal 💡

In this project, we turned on the LED on the LDR sensor data on Picobricks if the environment was dark, and turned off the LED if it was bright. By processing the LDR sensor data, you can code a nightlight or table lamp in your home to turn on automatically in the dark. You can use the relay on Picobricks for this.

#2 Action – Reaction Project with PicoBricks

As Newton explained in his laws of motion, a reaction occurs against every action. Electronic systems receive commands from users and perform their tasks. Usually a keypad, touch screen or a button is used for this job. Electronic devices respond verbally, in writing or visually to inform the user that their task is over and what is going on during the task. In addition to informing the user of these reactions, it can help to understand where the fault may be in a possible malfunction.

In this project, you will learn how to receive and react to a command from the user in your projects by coding the button-LED module of Picobricks

Details and Algorithm

Different types of buttons are used in electronic systems. Locked buttons, push buttons, switched buttons… There is 1 push button on Picobricks. They work like a switch, they conduct current when pressed and do not conduct current when released. In the project, we will understand the pressing status by checking whether the button conducts current or not. If it is pressed, it will light the LED, if it is not pressed, we will turn off the LED.

#1 Get Started with PicoBricks – PicoBlink

In real life, the employee, who has just started to learn the job, first undertakes the most basic task.The cleaner first learns to use the broom, the cook learns to use the kitchen utensils, the waiter to carry a tray. We can increase these examples. The first code written by newcomers to software development is known as “Hello World”. Printing “Hello World” as soon as the program starts on the screen or console window in the language they use is the first step in programming. Like a baby starting to crawl… The first step to robotic c oding, also known as physical programming, is the Blink application. It means winking at robotic coding.

Details and Algorithm

There are 1 x 5mm red LED and 1 x WS2812B RGB LED on Picobricks. While normal LEDs can light up in one color, RGB colors can light up in different colors, both primary and secondary colors. In this project we will use the red LED on Picobricks.

In the project, we will write the necessary codes to turn on the red LED on Picobricks, turn it off after a certain time, turn it on again after a certain time, and repeat these processes continuously.
