The Arduino UNO™ is equipped with 6 analog inputs. Some projects call for more analog inputs, e.g. sensor- or robot projects. This shield only uses 4 I/O lines (3 digital, 1 analog) but adds a whopping 24 inputs, so in total you have 29 analog inputs at your disposal.

Let’s add a graphic touch display to our Arduino-like boards, with dedicated hardware and three libraries. After showing you four prototyping boards from the Fishino series (UNO, Fishino 32, MEGA, Guppy… and the fifth is on its way!), we started to feel the need to propose some electronics on the side. In particular,…
We built a small musical instrument that will delight children and will allow them to play 8 notes and shift their frequency as desired using a potentiometer. Projects like the laser harp published in the previous post have accustomed us to seeing challenging circuits based on synthesizers and microcontrollers to produce musical notes, yet…
This DRV8833 dual H-bridge motor driver is the substitution of TB6612FNG Dual Channel Motor Driver. It can be used for bidirectional control of two brushed DC motors at 2.7 V to 10.8 V. It can supply up to about 1.2 A per channel continuously and can tolerate peak currents up to 2 A per channel…
Now available in our store the new TFT shield for our Fishino boards but also for Arduino. This is a shield mounting a display with good performances, that we are going to describe in this article. These are the main features: fairly small dimensions (2.4″ o 2.8″ display); resolution of 320 x 240 pixels, with high…
