0.91″ SSD1306

Preamble

I bought this, 0.91″128×32 IIC I2C White DIY OLED LCD Display Module 3.3V Fr PIC Arduino Hot im and connected it to an Arduino Mega, SDA/SCL/GND and connected to 5V and thought that I had broken it.

PWM.h for Arduino

Preamble

Following on from Vaping – Box Mods, I was trying to compile NewPWM, from Github: OpenSource Vape/ Smart_PWM_Test, and I was constantly getting the error:

NewPWM.ino:13:17: fatal error: PWM.h: No such file or directory

I searched google for ages, couldn’t find anything. Then, finally, I searched on Stack Exchange Arduino and found this answer from Mavidad, to Generating PWM signal 1-2 ms @ 333 Hz). NewPWM requires PWM.h from GoogleCode: arduino-pwm-frequency-library.

Grove connector

Preamble

In an attempt to answer the question on StackExchange Arduino, What type of connector does the GROVE system use?, and after looking up the Grove system, I contacted the technical support team at Seeed. I promptly had a reply, and below is the information that I received.

3D printers

Preamble

After having purchased a number of parts made by 3D printers, and seeing that the DIY printers are controlled by Arduino Mega boards, with a RAMPS 1.4 shield, I thought that I would look into them.

USB Shenanigans

Preamble

I was watching youtube tutorials, and saw this video.
Arduino Tutorial #14: Leonardo as Mouse

The case of the broken Pro Micro (reprise)

Revisited – one year later

Looking at this issue again, The case of the broken Pro Micro, one year later, when I connect the Pro Micro to a USB port on the PC, it is just not recognised. It is worth noting that I was using a newer version of the Arduino IDE (1.6.11) this time around. Last year I was using version 1.6.5.

Programming the Arduino Ethernet Board

Preamble

Following on from The case of the broken Pro Micro, I wanted to use my Arduino Ethernet Board, which is basically an Uno and an Ethernet shield fused together on one board, as an AVR programmer for the Pro Micro. For a recounting of this tale see The case of the broken Pro Micro (reprise).

However, before I could use the Arduino Ethernet board as an ISP, I needed to figure out how to program the Arduino Ethernet board, as there is no USB port.
