Pinguino PIC18F4550

Pinguino Banner

I’m trying out the Pinguino platform, which is made for Microchip PIC MCUs and it mimics the Arduino environment. It uses programming syntaxes that are very similar to the Arduino environment. It is to make the programming of PICs easier. Since it’s an open source platform, the firmware (bootloader) and schematics are openly available at their website. I’m using a …

HC-SR04 Ultrasonic Sensor on PIC

Hcsr04 Banner

HC-SR04 is a very common ultrasonic sensor and it is normally found in Arduino kits or projects. The library for this sensor is widely available for the Arduino platform but not for PIC. I’ve been asked to help to write a simple PIC code to interface with the ultrasonic sensor. It’s actually very simple by referring to the timing diagram. …

Bluetooth Mini Robot

Bluetooth Mini Robot Banner

Got another new robot kit and decided to create a bluetooth controlled robot with it. It’s from DFRobot and it’s called the MiniQ. Here it is assembled. Created a simple circuit on a donut board with a L293 H-Bridge and Arduino Nano. It is powered by a 2 cell Lithium Polymer battery. Typically each cell provides 3.7V so that amounts …

Programming Arduino using Atmel Studio 6

Arduino Atmel Banner

Arduinos are based on Atmel microcontrollers, and they can be programmed using Atmel’s native IDE – Atmel Studio 6. The main reason to use Atmel Studio 6 instead of Arduino IDE is because it provides better performance, Arduino IDE might be easy to use but it is slow because of inefficient compilation. It takes more cycles to execute an instruction …
