nRF24L01 – 2.4 GHz radio modules
Using the nRF24L01 and the RF24 library, you can exchange data between microcontrollers via 2.4 GHz radio. I show how it works.

Read MoreI introduce the ADS1220 4-channel, 24-bit A/D converter and my associated library using several example sketches.
Read MoreTo save valuable flash memory on ATtinys when using I2C, you can use alternatives to Wire.h such as TinyWireM. I show how it works.
Read MoreThe ATTinyCore package enables you to program a large part of the ATtiny family via the Arduino IDE. I show how this works with or without bootloader.
Read MoreI compare the members of the MCP23x1y family: MCP23016, MCP23017, MCP23S17, MCP23018, MCP23S18 and show how to control them.
Read MoreI show how to use a MOSFET as a switch and which parameters are relevant for the selection of the right MOSFET.
Read MoreCompared 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.
Read MoreI 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.
