Some questions:

1. How do I test the value of a pin if it is LOW or HIGH. Look at the screenshot you created above. The IF statement isn’t complete.
It says: if (digitalRead(3))

but it should be: if (digitalRead(3) == HIGH)
or
if (digitalRead(3) == LOW)

I tried but could not put them in the = operator block. It appears there used to be a ‘pin test’ block from earlier blog posts but I don’t see it at all.

2. How do you tell it how to generate code in the setup function? It appears to generate pinMode commands but how do I initialize variables to a particular value?

3. I do not see a block that allows you to turn on the internal pull up resistors on the digital pins. This is useful to use if you are using push buttons (because otherwise I need to physically add a pull down resistor on).

4. Is the I2C Read and Write blocks still in beta? Just some things to think about… The address of a device is normally 7 bits and should be bit shifted before passing to the wire library. Normally I do this in my code using the following macro:

#define SEVEN_BIT_I2C_ADDRESS(x) ((x) >> 1)
const int I2CAddress = SEVEN_BIT_I2C_ADDRESS(0xD0) ; // for device at address 0xD0

Also most device AND register addresses are in hex. I tried adding in a hex value for the register address value in the I2C blocks and could not put them in.

Oh and as an FYI the Wire library calls have changed for Arduino 1.0. The ‘send’ and ‘receive’ methods have been changed to ‘write’ and ‘read’ respectively.

The compiler now gives the error: As of Arduino 1.0, the Wire.send() function was renamed to Wire.write() for consistency with other libraries.

Sorry for the long post.

I can’t find serial.read() in Ardublock.
This makes me a little trouble.
