This project was done in order to experiment with the Automotakit breadboard board which is based on the ATMEGA256A3U chip. The use of a DAC, ADC , low pass filter, PWM, basic I/O, current control, clock setup, and interrupts on an Atmega chip are some of the topics explored here. In order to experiment around, the datasheet […]

This article describes a simple continuity tester, based on an ATtiny85 and a piezo buzzer, designed for checking circuit wiring, or tracing out the tracks on a PCB: It has a low threshold resistance of 50Ω to avoid false positives, and passes less than 0.1mA through the circuit under test, to avoid affecting sensitive components.

In this article I’ll try to show how to use an MSP430 with a DAC7564. This is probably the first from a series of articles showing different devices I plan to use in a project. The DAC7564 The DAC7564 is a low-power, voltage-output, four-channel, 12-bit digital-to-analog converter (DAC). The device includes a 2.5V, 2ppm/°C internal
