ADS1220 – Part 2: Applications

About this post In the last post, I introduced the ADS1220 24-bit, 4-channel A/D converter and my associated library. In this sequel, I will show you how to…

MCP23x1y Port Expander

I compare the members of the MCP23x1y family: MCP23016, MCP23017, MCP23S17, MCP23018, MCP23S18 and show how to control them.

The MOSFET as Switch

I show how to use a MOSFET as a switch and which parameters are relevant for the selection of the right MOSFET.

EEPROM Part 3 – External SPI EEPROMs

Compared to I2C-based EEPROMs, writing data to SPI EEPROMs is faster, especially for bulk uploads. I explain how this works and will introduce my library for the SPI based EEPROMs.

EEPROM Part 2 – external I2C EEPROMs

I show how you can use I2C controlled EEPROM ICs with your microcontroller. This works very comfortably with a library, but it can also be done without it.

SIM800L module

With the SIM800L, you can add mobile phone functions to your projects, e.g. make calls or send measured values via SMS and much more.

TCA9548A – I2C Multiplexer

I show you how to use up to eight I2C components with the same address with the I2C multiplexer TCA9548A. Alternatively, you can use MOSFETs as well for this purpose.

DCF77 – Radio Controlled Clock

Here you will learn what the DCF77 radio clock signal is, how to receive it, how to evaluate it and how to use it optimally together with the library RTCLib.

DS3231 – Real-time clock

In this article I will present the features of the real-time clock (RTC) DS3231 and how you can use it with the RTCLib library.

Remote shutter for smartphones

I show you how to hack a remote shutter for your smartphone to control it via an Arduino. Moreover: problem-solving for long-term operation.
