Five Things To Remember (Pun!) About Arduino EEPROM
EEPROM stands for Electronic Erasable Programmable Read Only Memory and is the place in chip memory where data can be stored in the Arduino/ATMega328 even after power down. This can be useful! The Arduino site has specifics on the EEPROM … Continue reading
Left and Right Blink Proximity Demo
Moore’s Law has been trumped, in that I have doubled the resolution of blink proximity in a single week. So what, you ask? Well, it means that the robot can now turn toward or away from obstacles. Or, even more … Continue reading
RGB display for timer
Today I spent some time thinking about possible simple products that I could market while I continue to work on my robot. One thought that came to mind was a color-coded illuminated egg timer. It would have an RGB LED … Continue reading
Flicker Object Detection
Can a small robot detect objects by flicking a light on and off? If so, then all I need to do in order to add object detection capability is add a small lamp to my robot at a cost of … Continue reading
Object detection by photocell
A photocell is a poor substitute for a camera, but it’s a lot cheaper too. So the question for grisbot is whether a photocell is sufficient to detect an object nearby. Here’s one possible solution. Suppose an object — say, … Continue reading

Rewiring to streamline reprogramming
Each time I re-program Grisbot, I have to move the ATMega328 microcontroller chip from the robot to the Arduino platform and then back again. It was difficult to pry the chip on and off the breadboard each time because several … Continue reading
ATTiny44 / Arduino programming pin connections
The MIT High-Low Tech tutorial on using an Arduino board as an ATTiny programmer has a diagram for connecting an Arduino to program an ATTiny45, but not for programming an ATTiny44. So I cross-referenced the corresponding SCK, MISO, and MOSI … Continue reading
Grisbot Light Follow Test 2
In the following test, I have incorporated the light follow sketch into the general grisbot sketch. In other words, by using the graphical user interface written in Scratch, the user can either program the robot for following paths or for … Continue reading
Mic Check, some progress
On the left is a swatch of code that I wrote to read the analog input from the microphone circuit and print it to the serial monitor. On the right is the serial monitor. Under normal circumstances, the value read … Continue reading
Noise Meter Challenge
The Big Brained Superheroes Club has issued a challenge to build a noise meter, and so I thought I would give it a try. Hence I looked up a web page at the arduino site for building a noise meter. … Continue reading
