  1. Part 1 - Hardware and Schematic Part 2 - Robots Filippo, Bipe and Spider Let us see now the analysis of the firmware describing those functions that are common to all the robots such as the procedure that reads the distance from obstacles by means ...
  2. Filippo robot Filippo is a biped robot whose movements are assigned to only two servos, but with this robot you can experiment with robotics without spending large sums. It is able to walk and turn around, then you can direct it in any direction, ...
  3. Part 1 - Theory In the first part of this discussion, the features of ACS712 device were briefly discussed. Now we will use that theory to implement the ACS712 sensor to make a simple DC current meter. The analog output voltage from the sensor is ...
  4. Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including, over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, ...
  5. The idea behind this post is to bring together some robot designs and trasform them in a new device with new hardware and standard software (arduino of course) and so easier to use. These robots have three things in common: a mechanical structure, ...
  6. Temperature-indicator and temperature-based products have generated wide interest. There are numerous applications for such devices with many possible solutions, each with its own advantages and disadvantages. This idea discusses a sensor interface ...
  7. One tool that I've been missing at my lab at home is function generator. They tend to be a bit expensive, so I haven't bought one. I thought this might be a good opportunity to try and make one myself. I found a pretty common DDS (direct digital ...
  8. Part 1 Zoltan Gingl Two configurable analog ports allow you to connect many sensor types using two three-input connectors, each of which has a ground pin (Figure 4). One ground pin provides 3.3V power, and the other outputs the buffered reference ...
  9. A precision analog acquisition system fits in your pocket. Zoltan Gingl, University of Szeged, Szeged The circuit in this Design Idea combines a mixed-signal microcontroller, a USB UART (universal asynchronous receiver/transmitter), and a novel ...
  10. Jeff Wilson, STMicroelectronics Use two diodes and two capacitors to generate a negative voltage. This Design Idea describes a circuit employing a small microcontroller-based sensor module with only three connections: 5V dc, an RS-232 transmit-data ...
