Beyond the Arduino — Part 2

Last month, we established a hardware platform to work on. This time, we’ll dive right into working in a new environment.


Add a Real Time Clock to Your PIC Projects

RTCs have all kinds of neat uses in microcontroller projects. Get introduced to this wonderful world of timekeeping with the popular and inexpensive TinyRTC.


Driving LEDs with a Microcontroller

Typically, one of the first experiments people do when working with microcontrollers is to blink an LED. However, the thrill of this wears out pretty quickly, so let’s see what else can be done.

The RN4020 PICtail Plus BLE.
Bluetooth 4.0 is becoming the de facto standard when it comes to embedded device monitoring and control from iPhones and Android devices. Microchip’s BLE radio module is called the RN4020. Unlike many of the other BLE offerings, the RN4020 Bluetooth Low Energy radio module comes backed with a full load of example code and hardware development tools. This month, we’ll get started on the BLE path with Microchip’s RN4020 PICtail, a terminal emulator, and a laptop.
