Post Project 19: Bury the Hatchet, Unbury the Axe (3)
In the course of this article series [1] we first showed how to program a PICAXE chip and how to build basic input and output circuits (Elektor.POST Project No. 8). In the second installment (Elektor.POST Project No. 16) we covered the control of various types of switches, and how to calculate the appropriate component values for your designs. This time we will be looking at how to read and process values from analog inputs, describing multiple output types using circuits connected to a pulsewidth modulation (PWM) output, in combination with the already available PICAXE commands. We will also be able to position mechanical parts accurately using servos controlled by a PICAXE chip, as well as creating and playing monophonic ringtones!
