easyC ecosystem

This sensor has two pieces – the rain sensor and the simple sensor. The rain sensor has nickel-coated lines on both sides. It measures moisture and outputs the data to the simple sensor that reads it. The simple sensor comes with easyC connectors onboard, which enables quick and easy connection with Dasduino microcontroller boards.

With the easy-to-use simple rain sensor, farmers can save water in irrigation. The sensor will alert them to shut down the water supply when it senses rain. It can even act as an automatic on and off switch, like turning on wipers on a car when it senses rain.

Light is one of the most important things in the life of most living beings. This is why it is common to work with light sensors when learning about electronics. A simple light sensor has a light dependent resistor (LDR) and sensor on a breakout board for easy wiring. The simple sensor comes with easyC connectors onboard, which enables quick and easy connection with Dasduino microcontroller boards.

As the name suggests, an LDR will change its resistance depending on the amount of light it is exposed to. The amount of light and resistance are inversely proportional. The more light it is exposed to, the less resistance it will have. So if there is more light, the board will have a resistance of several hundred Ohms. If the resistor is in the dark, it will have a resistance of several thousand Ohms.

For very precise measurements of the amount of light, take this digital light sensor into account (ALS – Ambient Light Sensor). In addition, the LTR-507ALS also measures the proximity (PS – Proximity Sensor) of the object to the sensor. It sends all this data via I2C communication, which is easy to read via our Arduino library.

Micro:bit is a very interesting board with lots of options that are used by many children in school or hobbyists, but who can say no to new features! So we decided to make a micro:bit add-on that will enable internet connection via WiFi! Finally, you’ll be able to connect your micro:bit projects to the Internet and to connect to the well known Internet of Things. WiFi:bit add-on is easy to use through a MakeBlock add-on or using completed Python examples.

Just insert micro:bit to the add-on, plug in the power cable (required) and you are ready! Open the examples and start sending and receiving data from the internet. There are even two easyC connectors on the WiFi add-on, which allow the simplest connection of I2C sensors and actuators with micro:bit. There are also available pins on the board which are isolated on standard spacing used for breadboard connections or connections with cables to additional components!

Ever wanted to build your own weather station using Arduino? Then the BMP180 breakout board with precision sensor from Bosch might interest you. The digital sensor on the board precisely measures the changes in barometric pressure and temperature. It uses the piezoresistive effect to gather the information. Since the pressure varies depending on height, the sensor can measure altitude too. Very low current consumption and voltage allow this type of sensor to be used in many modern devices.

The design is 5V ready with an onboard regulator for 3.3V. The breakout board’s standard current consumption is very low, only 5 µA. It uses an I2C interface, and the I2C address is 0x77. No soldering, nor need for distinguishing between SDA and SCL is required due to easyC. The sensor has integrated EEPROM memory with data for calibration. The pressure is measured in steps of 1hPa (=0.01hPa =0,01mbar), and 0.1°C for temperature.

Product usage tips:

If there is an error while using the breakout board, see if it’s connected properly. Take a look at the pinout. If everything is properly connected, check if the I2C address of the breakout board is correct prior to programming it. The I2C 7-bit address should be 0x77. If everything is correctly connected and the I2C address is right, look through your code once again. There might be some bugs in the code that are stopping the sensor from working as it should.

BMP180 breakout board works very well in combination with any Dasduino board and OLED I2C 0.96” display breakout board. All of them use easyC so they can be connected in a matter of seconds. The BMP180 sensor can measure the barometric pressure and temperature, while the OLED display can show them. The breakout board also comes with two mounting holes so you can attach it onto something and it won’t budge.

To keep the sensor working for a long while, we would advise you not to use it in extreme conditions. Going over or below the temperature range will surely damage the sensor. Same with the pressure. Keep track of the current going through it. Allowing too high of a current through the breakout board will burn the sensor and render it completely useless.

Looking to add visuals to your Arduino projects? The I2C OLED breakout board is perfect for that. Because of its high contrast, you will be in awe of its crispness! The display is made from hundreds of LEDs, each representing one pixel in a 128×64 grid. Thus, it doesn’t need any backlight, and it needs less power than the classic LCD screens. That’s 8192 pixels all individually lit at your fingertips!

The design is 5V ready with an onboard regulator, so is compatible with any 3.3V board. The breakout board uses only about 20 mA, depending on active pixels. It is easy to control over the I2C interface. It is even easier to connect with the easyC system – no soldering required!

This device uses MCP47A1 which is a single channel, 6-bit digital to analog converter with I2C compatible serial interface. There’s no integrated EEPROM memory which would allow DAC register and configuration bit values to be saved at powered off.

RTC (Real Time Clock) is a device that carefully and precisely tracks time and dates. It is extremely precise, so it is more suitable for long-term time tracking than clocks on microcontrollers. This breakout can work with an extremely low current and thanks to the alarm feature and interrupt pin, it will allow a microcontroller to enter sleep mode until its awaken by this RTC.

It has a built-in battery holder (battery not included) and even if power is lost, real-time tracking won’t be affected.

We made the easyC system for faster prototyping and easy connection between the components. However, some of the components have only one easyC port or you just want your cable managmenet made better. What to do in those cases? The easyC hub comes to the rescue! It has six connectors so you can easily expand your circuit. It’s as simple of a device as it can get.

Product usage tips:

You can connect easyC devices to the hub like you would to any other easyC device. Just plug the preferred easyC cable into the hub and a device you’re working with. That’s all there is to it.

You should avoid working with the hub in wet environments to ensure it lasts a long time. Be sure to watch the operating voltage of your circuit. Since the hub works on 3.3V, higher voltages can burn it and render it useless. There is a hole in the middle of the board so it can be secured to any surface.

Product usage tips:

If you encounter errors when using the breakout board, see if it’s connected properly. First, look at the pinout on the board and your microcontroller. If everything seems OK, look at the connections on the breakout board. If all the wiring is correct, make sure that the breakout board’s I2C address is right. It should be 0x70. Everything as it should be so far? Go through your code again. There might be some bugs that are stopping things from working as expected.

The SHTC3 breakout board works wonderfully in combination with Dasduino Core and 16×2 easyC LCD. You can display temperature in one row and humidity in the other. Due to the easyC connections on all three, hooking all the devices together is as easy as it gets. The SHTC3 breakout board has two mounting holes so it can be attached to the project and won’t budge. The pins provided can be soldered if you don’t want to use the easyC ports.

To keep the longevity of the sensor, keep track of the current going through the circuit. Allowing an excessive amount of current to flow through it may cause the sensor to fail. It is not impact-resistant. When dropped from a high distance or at an odd angle, it can break beyond repair.
