When you think of the word ‘l293d’, what comes to mind? If you’re like most people, you probably think of something like, ‘Oh, that’s the chip that drives my robot!’ Right? Or maybe “Oh, that’s the chip that allows my robot to move!”. In this post we will explore what l293d actually is and how it does exactly what it does.

I2C, which stands for “Inter-Integrated Circuit”, is a serial bus interface. It was developed as an alternative to other communication buses such as SPI and UART serial ports. The I2C standard was created by Philips Semiconductor in 1982, but is now managed by the I2C Trade Association (www.i2c-ta.org). This article explains what I2C is and if IoT systems can use it.

The MCP23017 is a 16-bit port expander with 32 channels of 12-bit analog-to-digital converters and two generic 8-bit inputs / outputs. Unlike most other port expanders, the MCP23017 has an internal oscillator. The MCP23017 operates at 2 MHz, but can support frequencies up to 1 MHz; It can be cascaded and comes in an 18-pin PDIP package, so you can use it in breadboards and through-hole soldering perfboards. This makes it easy to connect it to other parts of the circuit.

The SPI has hardware synchronization capabilities, but there are some implementations without it. SPI cabling is implemented with a single master and multiple slave nodes.

The nRF24L01 is a low cost transceiver module that operates in the 2.4 to 2.5 GHz frequency range and uses FSK, GFSK, OOK and ASK modulation techniques to send packets to other radios in the area. The radio also has a built-in voltage regulator that allows it to operate with 5 or 3V power supplies, making it easy to implement in projects. The module can be used with an Arduino board or with any other microcontroller equipped with an SPI interface or pin header for its pins.

FreeCAD is a parametric 3D modeler made primarily to design real-life objects of any size. It is also great for architecture, engineering and construction projects. The FreeCAD application is written in Python and uses OpenCasCade, a powerful geometry kernel, for 3D operations. It’s open source, with an active community of developers and users.
