The robot arm uses an Arduino board so there are at least 6 analog inputs. The original board was a Robot Geek Geekduino, their version of the Arduino Duemilanove, with 8 analog inputs.

This Arduino project involves measuring both AC and DC voltages using the ZMPT101B voltage sensor and an analog pin, respectively. The AC voltage is read from the ZMPT101B sensor connected to pin A0, ...

This means a single analog input of the microcontroller is shared among all the input channels (except the 3-axis accelerometer). Four additional microcontroller pins choose which channel to read.

[Rodot] has programmed several games for the hardware, which uses an Arduino, 160×168 TFT screen, a 3 axis accelerometer, and two input buttons.

An innovative application of negative group delay (NGD) circuit embedded in a mobile platform for the real-time prediction of arbitrarily moving object position is developed in this article. The study ...
