Just wondering..... Do picaxe micro's have an issue like this or is this something just peculiar to it Arduino? The article addresses this issue by using a 3.3 refer Avoid this Cross Talk Problem when You Use the ADC Pins When any Arduino digital pins switch, they load the internal 5V rail on...

Especially in the instructions from China laughable.

My order came in today and it included a CD-ROM for the bot110 versabat. Gramps

Yes I believe up to 2 kg for this price.

Thanks erco! Even though it's after Christmas still got some great deals! Gramps

Erco, A great gift idea! My boy, Jeff (oldbitcollector)was 8 years old when we gutted our first tv chessis together. A Radio Shack 50 and 1 experimenter kit came later. By age 10 a commodore came into his life!

I purchased the book when I first became interested in learning to program the picaxe micro. Was a little disappointed but just attributed it to my own inability to understand what was going on. Gramps

It is truly amazing what you can learn just reading threads! I love low tech simple answers for complex questions! For example, detecting not only the keys on a Keypad Matrix but the position of a rotary switch or encoder or the state a dozen bumper switches with just one pin! Gramps

My son, Jeff, "oldbitcollector" has been building some really cool stuff with a raspberry pi (64bit)

Yup. I'm from the "hollow state" days...;)

"A typical microcontroller is a computer-on-a-chip including RAM and ROM, with strong I/O support, providing a single-chip solution." Whereas a microprocessor requires all the external stuff to make it work. Correct? But then there is a micro computer. How is it different from a microcontroller...

I didn't realize there was a difference between a microcontroller and a micro processor.

So I suppose all the micros are 8-bit.

Is the number 255 unique to picaxe chips or is there a bigger picture here?

It sure does! Nice build, too! Gramps

I didn't realize there was such a part! Very nice for just $20!

Yes! Love those simple low tech solutions!

In this project pot variable1 will represent the position of the steering axle and the end stops. Pot variables2 and 3 will be the two inputs from the magnetic line following sensors. (Hopefully) all three variables will steer the vehicle as it follows the buried signal line.🤔

Bill, thanks for posting. I'm away from the hardware right now and don't even have access to the Editor. Hopefully I can get back to this later Gramps

Thank you so much for everybody's help! Gramps
